ORGANIZATION
1. The 34th Session of the Executive Committee of the International Poplar Commission was held in Beijing, People's Republic of China, on 5 September 1988, at the kind invita- tion of the Government of China. Mr. M. Viart, Chairman of the Executive Committee (and Chairman of the Sub-Committee on Nomenclature and Registration) chaired the meeting. It consisted of a closed session of 8 members and 5 heads of Working Parties and Ad Hoc Committees as well as the Secretary of the Commission,
THE SESSION
2, The Session was opened by the Chairman of the Committee and the Provisional Agenda and Timetable for the 18th Session of the Commission were discussed. The Agenda and Timetable sent to participants with the invitation to the session were amended to include the adoption of recommendations (point 14). Furthermore, it was decided to hold the Joint Meeting of the Subsidiary Bodies in the afternoon of 6 September instead of the 7th as originally planned. The Committee agreed that the election of the members of the Executive Committee for the period 1989-1992 should be held in a closed session with one delegate per member country, on 8 September.
The Chairman lamented that the Vice-Chairman of the IPC, Mr. C. Vallée, and Mr. B. Tans, Chairman of the Working Party on Diseases, had been prevented for reasons of health to participate in the Session, and that Mr. J.P. Lanly, Director of the Forest Resources Division of FAO and Miss C. Palmberg, Branch Chief in the same Division, had been unable to participate in spite of their expressed wishes to do so.The Committee was informed that Mr. C.P, Cellerino would be the new Chairman of the Working Party on Diseases,
The procedures for election of the members of the Executive Committee of the IPC for the period 1989-1992 were discussed, Mr. M. Viart. informed the Coiimittee that he would retire as Chairman of the IPC. On behalf of the Committee, Mr. B, Giordano thanked Mr. Viart for his dedication to the work of the Commission and guidance during the many years of Chairmanship.
The Secretariat informed the Committee of the candidates proposed by member countries for membership of the Executive Committee. The need for an appropriate geo- graphic distribution of members for the dissemination of recent developments in poplar and willow technology was stressed. The Secretariat also informed the Committee of the offers received from member countries to host the 35th Session of the Executive Committee (Argentina, Canada) and the 19th Session of the International Poplar Commission (Spain).
111. POST SESSION INFORMAL MEETING OF THE EXECUTIVE COMMITTEE
6, The newly elected members of the Executive Committee for 1989-1992 met to elect the Chairman and Vice-Chairman of the Committee and discuss general business,By unanimity, Mr. Steenackers (Belgium) was elected as the Chairman and Mr. Wang Shiji (People's Rep. of China) as the Vice-Chairman of the Executive Committee,
7. Several proposals were made for additional members in order to ensure the coopera- tion of the necessary specialists, as provided for in the convention of the IPC.The following persons were coopted, subject to the approval of their governments:
Mr. D.S. DeBell (USA)
Mr. I. GUmUsdere (Turkey)
Mr. 0. Terrasson (Prance)
Mr. B. Tans (France)
Mr. C, Vallée (Canada) 2
PART II. REPORT OF THE 18TH SESSION OF THE INTERNATIONAL POPLAR COMMISSION
I, ORGANIZATION
1. The 18th Session of the International Poplar Commission was held at Beijing at the kind invitation of the Government of the People's Republic of China under theChairman- ship of Mr. Wang Shiji (China), with the assistance of two Vice-Chairmen, Mr0 3, Spaas (Belgium) and Mr. D. Cadahia (Spain) and two Rapporteurs, Mr. C. van Kraayenoord (New Zealand) and Mr. D. Terrasson (France).
2,, The Session was attended by 82 delegates, alternates and advisors from 19 member countries of the Commission: Argentina, Belgium, Bulgaria (People's Republic of), Canada, China (People's Republic of), France, Germany (Federal Republic of), India, Iran (Islamic Republic of), Italy, Korea (Republic of), Netherlands, New Zealand, Portugal, Spain, Tunis, Turkey, USA and Yugoslavia, Participants and observers totalled 133 from 27 countries, including Chile, Ethiopia, Kenya, Lesotho, Mexico, Sweden, Tanzania (United Republic of) and Zambia (Republic of).
II. OPENING OF THE SESSION
3. The Session was opened by the Chairman of the retiring Executive Committee, Mr., H. Viart, who called on Mr. Xu Youfang, Vice-Minister of Forestry, to address the session,
Mr. Xu welcomed the participants on behalf of the Ministry of Forestry. He emphasized the important role of forests and trees in counteracting the degradation of the environment caused by deforestation and other human activities. Drawing attention to the magnitude of the problem in China, Mr. Xu highlighted past achievements in tree planting and the active part played by 200 million Chinese citizens in attaining these achievements. In particular, attention was drawn to poplars as one of the most important - 'tree species for planting of shelterbelts to restore the equilibrium of the ecosystems and for establishing fast-growing plantations to satisfy various human demands, He pointed out that the meeting of Chinese and foreign poplar specialists was warmly wlcomed as a natural part of China's policy of opening up to the outside world and he offered best wishes for fruitful results of the deliberations,
Mr. L.I.J. Silva, FAO Representative in the People's Republic of China, thanked the Chinese Government and the organizers of the Session and welcomed the participants on behalf of the Director-General of FAO, Mr. H. Saouma. He also brought greetings from the Assistant Director-General, Mr. M.A. Flores Rodas, and the Director of the Forest Resources Division of FAD, Mr. J.P. Lanly. With reference to the Theme of the Session, "Poplar Cultivation: Towards 2000", he pointed to the role of forestry in meeting the threats of dwindling resources and a degraded environment. Tie urged foreign participants to take advantage of their stay in China to savour her culture and interchange views with national colleagues. He wished the participants every success in their work.
6. Mr. Wang Shiji was nominated Chairman of the 18th Session and Mr. D. Cadahia (Spain) and Mr. 3, Spaas (Belgium) Vice-Chairmen,
II. THE SESSION'S ADMISSION OF NEW MEMBER NATIONS
7 There was no submission of any new country to become a member of the Commission. However, the delegate from Mexico expressed his interest in being briefed on the conditions for membership and the delegate from Sweden expressed a similar interest. Both delegates were provided with the Convention of the International Poplar Commission,
IV, POPLAR CULTIVATION: TOWARDS 2000
8., The Chairman of the Commission, Mr. H. Viart, presented the paper on the theme of the 18th Session, 'Poplar Cultivation: Towards 2000". Its preparation had been based on replies to questionnaires sent to member countries and from reports received from the National Poplar Commissions, 3
It was lamented that only 10 countries had answered the questionnaire and urged the National Poplar Commissions in the future to send in their replies in due time in order that the paper on the theme could be as broadly based as possible and reflect the - situation in all the member countries.
The trends in consumption of and demand for poplar wood in the industrialized countries is influenced by changes in industrial processes and imports resulting in poplar wood being used more in higher priced products thanbefore. While the demand for poplar wood for pulp, chipboard and packeting has been falling, it has been increasing for plywood furniture and quality particle boards such as waferboards. The market for sawnwood appears stable.
11, In the developing countries there has been an increasing use of poplar wood for fuel and in particular for poles and small logs for rural construction and the consumption of poplar wood for these traditional uses has increased more than that for industrial wood. Although little is reported on the use of poplar and willow biomass, it would seem that more technical and economic evidence is needed before this production system is fully endorsed by National Poplar Commissions.
12. On the silvicultural side, P. deltoides and P. x euroamericana continue to be the most commonly planted species for high yield industrial plantations on good soils under irrigation while P. tricocarpa, and P. x inceramericana are first of all used for afforesr.ation on poor soils. More and more research is done on P. maximowiczii, and other Asian species like P. simonii will increasingly be planted for amelioration of the environment on poor sites. In this respect, Chinese geneticists, in collaboration with colleagues within the International Poplar Commission, will likely play a leading role. The interest for P. euphratica for planting on arid sites has increased. The Commission has taken the initiative to collect information on this species from relevant countries and a report on the results was presented under Agenda Point VII of the Session. More work is being done on producing hjgh-yielding clones of balsam poplars of the Tacamahaca section in order to be able to establish industrial plantations on poor soils. However, work still remains to be done on solvinghe problems of vegetative propagation of the poplars of the Trepidae subsection.
International interchange of cultivars has been growing and will probably continue to do so. It therefore becomes imperative that two basic conditions be adopted by exporters as well as importers: the vegetative material should be properly identified and measures taken to prevent the dissemination of pathogen agents.
Trialscontinueon reducing the cost of producing planting material and of planta'- tion establishment, The trend to reduce the length of the rotation will most likely continue and at the same time, the spacing will be subject to change. It should be stressed, however, that there is a growing gap between the research institutes, the poplar growers, and the industries, concerning the dissemination of results from research on these and other important issues of poplar cultivation.
In the discussions that followed the presentation of the paper on the theme, it was stressed that biomass was to be regarded as a concept of utilization and not as a product. The utilization of the tree is complete and covers a variety of products. This entails that economic evaluation of biomass has little meaning. -
Italy explained the decrease in demand for poplar for pulp and paper, as stated in the national report, as a result of technological developments in the industry . The processing speed in the mills has been increased drastically and it was discovered that poplar wood was not suitable for this process.
V. MAJOR DEVELOPMENTS IN THE FIELDS OF POPLAR AND WILLOW POLICY AND LEGISLATION
Under the Chairmanship of Mr. J. Spaas (Belgium), the report was presented by Mr. L. Zsuffa (Canada) in the absence of Nr.G. Vallee (Canada), The report was based on 14 national reports and may not necessarily reflect the general trend on this issue for all member countries. -4
18, Most of the countries have not introduced significant changes. However, three states, Argentina, the Republic of Korea, and Turkey, have initiated a dynamic plantation extension policy implicating financial participation by the Government, Restriètive measures have, on the other hand, been put in force in two countries. In New Zealand, financial support of plantation establishment has been withdrawn and restrictive regulations have been introduced in Italy, motivated by ecological considerations, A renewed interest was noted for aspeus, either for the management of natural stands (Canada) or for the establishment of plantations (Republic of Korea).
19. During the discussions, Mr. M. Dorflinger of the Federal Republic of Germany regretted that the report from the German National Poplar Commission had arrived too late to be taken into consideration and highlighted the 3 principal elements that influenced the forest policy of his country: the uncertainty of future forestry development in view of the forest decline attributed to air pollution; the conversion of surplus agricultural land to short rotation industrial plantations; and the limitations imposed on the use of clonal material in commercial plantations.
VI. RECENT TRENDS IN POPLAR AND WILLOW STATISTICS AND ECONOMICS
20. The report was introduced by J. Balatinecz (Canada) and Mr. J. Spaas (Belgium). The annual harvest in the USA and Canada has been estimated at 25 million m3 with Canada accounting for approximately 68%. Other countries with major poplar harvests were Italy (4.1 million mi); Turkey (2.4 million m3); France (2.3 million m3); Hungary (1.3 million m3); Argentina (1.0 million m3 of which 30% is willow wood) and Spain (0.6 million m3). China is, of course, a rñajor producer of poplar wood, but no data are available on global harvests from this country.
21. Because of the trend within the EEC to convert some agricultural lands to forestry, an effort has been made in Belgium to collate statistical information on yields and financial returns of pop'ar cultivation and to calculate net present values and internal rate of return of high yielding clones under different growth conditions in respect to yield class or site index, spacings and rotations. The results for two cultivars, P. x euroamericana cv. Ghay and P. x interamericana cv, Baupr, were presented. The formulas and software developed would permit the investor to estimate the financial feasibility of plantations under different ecological and market conditions. The calculations were based on healthy plantations.
VII. POPLAR AND WILLOW IDENTIFICATION AND VARIETAL CONTROL
22. The Chairman of the Sub-Committee on Nomenclature and Registration first r-eported on the work done on P. euphratica. In view of the increasing interest for this species and the relative scarcity of information available, a mini-monograph had beenproduced based on a questionnaire circulated by FAO. The species is distributed over 3 continents and is particularly adapted to arid and semi-arid, salty and sometimes cold regions.In China, natural stands cover some 570,000 ha. Mr. Viart suggested that one of the IPC member states concerned with the conservation of this species should establish a collection of provenances that could form the basis for a serious breeding programme.
23, Mr. Viart then presented the paper dealing with the necessity for stricter control of nomenclature and proposals fora simplified registration procedure. He underlined the many irregularities in nomenclature found in national reports and reminded participants that the IPC is the international organization authorized for registration of poplar cultivars. He suggested that an updated version of the 1971 Registration Catalogue be presented at the next meeting of the Executive Committee. In order to be able to achieve this goal, Mr. Viart suggested that the National Poplar Commissions establish a registra- tion unit that would draw up a national list of cultivars, according to the guidelines contained in his paper, and send these to the Secretariat who would then collate a new and more complete International Catalogue of Registered Poplar Clones.
24. After the presentation, Mr. A. Alonzo declared that Argentina had selected 3 new clones of P. deltoides and would prepare them for registration. 5
VIII,POPLAR CULTIVATION Ai'D SILVICULTURE
The Chairman of the National Poplar Commission of China, Mrs. Xu Wei Ying, presented the Chinese report on activities related to Poplar and Willow Cultivation, Exploitation and Utilization and gave an overview of the development of poplar cultivation in China. It was pointed out that the Government had supported tree plantingwith poplars since 195O line plantings for improving ecological conditions and agricultural production and block plantations, mainly for the production of rural construction timber but increasingly also for industrial timber. More than 5 million haof farmland had been protected with shelterbelts in the north, and fast-growing timber forests now cover 267,000 ha. However, the goal is to increase timber plantations to 16.7 million ha by 2010, and poplar plantations would account for two-thirds of this area,
Extensive research, import and trials of exotic species and cultivars will assist this effort, In the past, the Italian poplar cultivars Lux, Howard and San Martino have been extensively employed and have been crucial in achieving improved growth rates in comparison to cultivars of indigenous species.
Large areas of natural poplar stands remain to be managed. In the Heilongjiang Province, there are 890,000 ha of P. davidiana in pure and mixed stands. In the basin of the Tarium River, Xirijiang Autonomous Region, there are 280,000 ha of Populus nigra, Populus alba, P. canescens and P. laurifolia. Therere also large areas of natural poplar stands in Gansu, Ningxia and Qinghai Provinces. Many problems still exist in the management of these natural stands.
To assist in the developing work, the Poplar Commission of China, founded in 1980, has established six working groups corresponding to the subsidiary bodies of the IPC. Improvements wete made through provenance trials and plus tree selection of P. tomentosa and P. hopeiensis; better control of diseases in planting stock; introduction of deep planting in dry to arid zones and registration of new poplar clones. The International Poplar Commission had been instrumental in promoting this work through the establishment of the necessary contacts with foreign research institutes.
In the following discussions it became apparent that although large areas were known to be covered with P. euphratica, no information was available on exact areas.
At the request of Mr. Alouzo (Argentina) the Commission was informed tat willows were considered so important in Argentina chat a special working group had been organized to deal with these species.
IX. POPLAR AND WILLOW PROTECTION
a) Report of the Working Party on Poplar Diseases
Mr. J,T. Spaas (Belgium), Vice-Chairman of the 18th Session, conducted the Session on its third day. The report of the Working Party on Diseases was delivered by the new Chairman, Mr. G,P. Cellerino.
Reports on the sanitary situation of poplars in the different countries have made it possible to compare the distribution of pathogen agents and, in particular, to inter- change information on areas affected by Coryneum purpureum, which seem to be limited to China, and Hendersonula toruloidea which apparently only affects Iraq.
Particular attention was given to the bark parasite, Dothichiza populea which causes increasing concern to affected countries. Reports on modifications of virulence indicate that D, populea is highly variable, Attention was focused on the extension of the pathogen as a result of physiological stress and oct the severe economic losses caused by secondary fungii like Trametes trogii.
34, The leaf diseases, Marssonina brunnea and, in particular, the rust diseases (Melanpsora sp.) continue to be a major cause for losses in the plantation. Because of high variability of the diseases, work had been concentrated on their taxonomy. 35. Gravity of risk and symptomatology were highlighted as important factors for all countrie affected by virus diseases. This is particularly important for China because of the large extensions of plantations of Populus delto{des clones.
36, In the discussion, it was brought to the Commissions attention that the presence of Septoria muciva, an important pathogen in North America, had now also been reported from Argentina. It would therefore be necessary to examine the possible synonomy with
Mycosphoraella. -
37. Thd representative from Germany requested that the Working Party become involved with forest damage attributed to air pollution. Mr. heng (China)reported that only very localized damage of this kind had been observed in China close to factories.This was supported by Mr. Cellerino, who was of the opinion that the forest damage in Europe referred to by Mr. Doerflinger was caused primarily by physiological stress.
b) Report of the Working Party on Popir Insect Pests
The report of the Working Party was presented by its Chairman, Mr.Cavalcaselle, It was pointed out that a substantial report on the meeting of the Working Party in Belgium, September 1986, had been published by the National Poplar Commission of Belgium. This report had been distributed and contained recommendations that remain valid today, but still needed to be put into practice.
It was reported that methods on biological control of insect pests were receiving increased interest and attention as well as the breeding of pest resistant clones. The Commission was advised that the trend for phytosanitary protection of poplars towards the year 2000 would be noticeable for the increased use of these methods and a reduction of the use of chemical control methods.
The main object of discussionswasthe planting of clone mixtures. Participants from Germany insisted that this form of cultivation would reduce the biological risk and reported that good results had been obtained with aspens and balsam poplars in forest stands, Mr. Bisoffi (Italy) pointed to the economic, practical and pathological difficulties and suggested that the enlargement of the genetic base of the planting material and the reduction of the risk factor could be better achieved through a mosaic of monoclonal plantations.
X. LOGGING AND UTILIZATION
The Chairman, Mr. Balatinecz (Canada), highlighted -the activities since the last meeting in Brussels. He indicated that the trend in harvesting was to use all-tree harvesters in plantations and specially-constructed machinery for short rotation biomass plantations. This should be seen as the result of a general trend that the outputs of research were now filtering down to the operator.
The trends in wood products were influenced by the need to reduce waste. Traditional uses would still be important but high value products would be more actively marketed in the future. Among the new developments noticed were laminated veneer lumber; waferboards and Oriented Strand Boards; laminated timber Parallel-Strand-Lumber (Parallam); 1-beams and combination panels. The need for now opportunities was stressed and research would therefore be an important sector in the coming decade,
The discussion following the report centred on the interchange of development criteria between breeding researchers and the industry, It was stressed that the breeding should aim at producing trees with high density and straight form, apart from resistance to pest and discaes, tivergeu opinions were however voiced on this issue and it became apparent that the breeders would have to aim at producing trees that would satisfy a variety of industrial requirements. -7-
XI. BREEDING AND SELECTION OF POPLARS AND WILLOWS
The report of thed hoc Committee was presented by its Chairman, Mr. V. Steenackers (Belgium). More than twenty papers had been received and discussed in the past days and the majority of them focused on the need for genetic material for rational breeding programmes. It was stressed that the gene pool should first of all be represented by the national populations of poplar and willow species, and secondly by exotic poplars made available through international exchange.
It was brought to the Commission's attention that the populations of some native species were rapidly disappearing, either because they were displaced by agriculture or constructions, or because they spontaneously hybridize with cultivated clones. Natural stands of Populus nigra have almost disappeared in Europe and the situation for Populus deltoides in North America is very serious.
It was pointed out that the exchange of genetic material also carried a risk. Pathogens and insects have been transferred together with the germplasm as happened with the introduction of leaf rust (Melampsora sp.) to Australia, New Zealand, Argentina and South Africa; of Poplar Mosaic Virus to China, and Septoria musiva to Argentina.
The Commission's attention is therefore called to these two issues: conservation of natural gene pools and safe exchange of genetic material as being of utmost importance during the years towards 2000.
XII, BIOMASS PRODUCTION SYSTEMS FOR THE SALICACEAE
48, The report of the Ad Hoc Committee on Biomass Production for the Salicaceaes was presented by L. Zsuffa (Canada). He highlighted the key Issues that had appeared in the 16 country reports reviewed. The use of poplars. in agroforestry systems and a more complete utilization of the poplar tree is reported by all countries. Agroforestry with complete utilization of the -combined biomass is considered a biomass production system by the Ad Hoc Committee. Agroforestry is intensively practised in many parts of China mainly wit-h poplars as the forestry component. Agricultural cropping is practised during the first 2-3 years after plantation establishment, and utilization of the trees starts with the first pruning, when leaves are used for fodder and branches for fuel.
Biomass production in dense, short rotation plantations of poplars and willows, regenerated by coppicing, has been introduced on an experimental scale in Canada, France, Belgium and USA. Trials on a small scale are being conducted in China, Hungary, New Zealand, Pakistan and Turkey.
The speaker then summarized the progress made on the 1984-88 work programe. It included a project proposal for a Poplar Biomass project in China; development of a manual for biomass production to be printed in early 1989; development of a data base; standards for biomass qualities and the publishing of a woody biomass terminology.
XIII. ADMINISTRATION AND OPERATION OF NATIONAL POPLAR COMMISSION
A synthesis of the 14 national reports received by the Secretariat was prepared by Mr. C. Vailde (Canada) and, in his absence, presented by Mr. M. Viart.
Argentina. The National Poplar Commission now depends on the National Forestry Institute (IFONA) whose President is also Chairman of the Commission. Three regional Commissions have been created (Delta, Mendoza-San Juan and Rio Negro Colorado). The 5 Working Parties and the Executive Committee meet every month. A symposium on silvi- culture and breeding was held in April 1987 and the proceedings printed and made available to the FAO Secretariat,
Bulgaria, No activity recorded. 54, Canada. The Poplar Council of Canada, representing the National Poplar Commission, has held 4 meetings during the period, 2 of them together with the Poplar Council of the United States. The report from these meetings and 2 newsletters have been distributed. A registry on poplar clones and populations has been kept up to date.The Council has 200 members including 40 corporations.
Korea, (Republic of),After the regrettable death of Mr. Hyun, Dr. Chong Sup Shim was elected as the new President of the National Poplar Commission.Meetings have been held every 2 weeks in consultation with government agencies and representatives from the private sector and a symposium and study tour organized.
Spain. In spite of being well organized, the National Poplar Commission's activities have been limited due to financial constraints. Frequent excharigesof genetic material have been made with Italy and Bulgaria.
57, United States of America. Four meetings of the Poplar Council have taken place between 1984 and 1987, two of them together with the Poplar Council of Canada.A paper on recommended poplar clones has been published,
58. France. The National Poplar Commission met in 1985 and 1987 while the Working Groups have met annually. Since the restructuring of the NPC in 1984, representatives of the industrial sector have been associated with its work.
Hungary.. Many institutional changes have taken place in the country recently and the National Poplar Commission is presently not functioning.
Italy. The National Poplar Commission introduced new statutes in 1986 and the role of its Executive Committee has been changed. The Executive Committee now has 14 members: I President; 3 Vice-Presidents; 2 representatives of the poplar growers; 2 tepresenta- tivea from industry;.1 representative from the marketing sector and 5 regional representatives.The Zxpeimental Station at Casale Nonfarrato has exported 17 clones and imported 3,
6]., New Zealand, The National Water and Soil Conservation Authority continued to act as the National Poplar Commission of New Zealand. However, this Authority has beendis- banded since 1April 1988 and the functions of the New Zealand Poplar Commission are being carrtd out by staff of the Plant Materials Group of the Soil Conservation Centre, Aokautere. This Centre has been transferred from the Ministry of Works and Development to the Department of Scientific and Industrial Research from 1 April 1988.
62. Pakistan. No institutional changes or activities reported.
Portugal. No comments are given in the national report on administration of the National Poplar Commission,
Turkey. Annual meetings were organized by the National Poplar Commission together with study tours to various parts of the. country.Genetic material was interchanged with four countries (Afghanistan, China, New Zealand, Yugoslavia),
Yugoslavia. The National Poplar Commission has been very active. After reotganiza- tion in 1987, the Commission became an independent board of the Executive Committee,of the Yugoslav Chamber of Economy. The Commission includes representatives from socio- political communities., forestry, wood industry, agriculture, water management and research. The President is Mr. Pavle Vrataric. During the last 4 years, the Commission has had 16 meetings and organized 5 symposiums. The proceedings were published in the TOPOIA Scientific Bulletin of the Yugoslav Poplar Commission and in the publications of the Poplar Research Institute. The Commission has continued to stimulate the exchange of genetic material and information with other countries, XIV, RECOMMENDATIONS OF THE COMMISSION
66. Under the Chairmanship of J.T. Spaas (Eelgium) the Commission reviewed the recom- mondations formulated by the subsidiary bodies arid, after discussions, adopted the following recommendations:
Nomenclature and Registration
In view of the necessity for a strict nomenclature of the poplar and willow cultivars to facilitate the international exchange of living material and information, it is recommended that:
- fancy names should be given to cultivars released for cultivation in accordance with the rules of the International Code of Nomeaclature of Cultivated Plants and registered at national level by a Registration Authority duly mandated by the Government;
- subsequently the names of the registered cultivars should be listed by every national Registration Authority and sent with brief comments to the Secretariat of the International Poplar Commission acting as an International Registration Authority;
- the Commission should issue an international list of names of poplar cultivars. A provisional edition should be made available for the next session of the Executive Committee if possible.
Poplar and Willow Protection
a) Diseases
careful attention should be paid to the correct identification of the pthogens and to the elaboration of normalized detection systems in the different member countries;
- spcies identification should be completed with a study of the pathogen variability (spreading area, strain aggressiveness, etc.);
- selection of tolerant or resistant cultivars should be intensified, as a control method, with perfect knowledge of the pathogetis arid of consequent. damage.
69. Insect Pests
- intensify research on pheromones, repelients and integrated control methods, improving the transfer of information gained in all the member countries;
intensify cooperation with poplar breeders and physiologists for a better evaluation of the existing correlations between the presence of some chemicals (polypheriols, sugars, cerpenes, etc.) and the resistance to different pests;
- pay attention not only to primary pests, but also to the ,roae that secondary pests could have as vectors of viruses and other diseases.
Logging and Utilization
7O. The following recommendations were made on this issue:
- Member countries of the IPC (both developing and developed) should encouragethe development of small-scale flexible conversion technologies for poplar and willow wood, - 10 -
Member countries of the IPC should endeavour to maintain and exchange economic information about the production and utilization of poplar/willow wood. Th aggregate economic data should include:
- Total forested land Area occupied by poplars/willows Area of new plantations - Quantity of wood harvested -. Quantity and types of poplar/willow products - If available, costs and prices of wood and wood products.
Breeding and Selection
71, The following recommendations were adopted on breeding and selection:
- Preservation of natural populations should be sought through legislation in order to safeguard valuable genetic material for the future. Wherever possible, and in particular for endangered species, populeta should be established either
in situ oreXsitu. -
The exchange of genetic material should be strictly cont.rolled, to avoid the transfer of pathological and entomological agents, and seed preferred for cuttings or plants wherever possible. 1xchange of clonal material shouldbe in the form of in vitro cultures. Exchange should follow the practical guidelines suggested by the Ad Hoc Committee in their report.
- Each country should produce, circulate end periodically update, a complete list of pathogens and insects affecting poplars and willows in their national territories. International cooperation is also invoked for the identification of.che different species and races of Melampsorae sp.
- Cooperation on the exchange of genetic material should be strengthened. Member countries are urged to prepare a list of species or provenances they would like to obtain and the material they would make available for other countries.
- Initiate a dialogue and an ongoing cooperative programme between breeders and users of poplar and willow wood concerning wood quality requirements for different products.
Biomass Production
72. Thmultipurpose tree production systems are not well defined. This creates problems in proper application and delays the creation of necessary data bases It is therefore recommended to:
- establish a framework of multi-purpose tree production systems;
- develop biological and engineering criteria for model systems which meet the requirements of productivity, environmental improvements and socio-economics;
- identify locations for model-system development and demonstration;
- identify gaps in knowledge pertaining to model systems and design research to establish a data base.
73, It is generally agreed that multipurpose production systems lack properly designed planting stock. It is therefore recommended to:
- identify ideotype planting stock parameters for system components; and
- initiate cooperative proeets in breeding of ideotype planting stoak - 11
Concern was expressed for the rapid deteriorationofour global environment. Efficient multipurpose tree production systems can play a major role in reversing this trend. It is recommended therefore:
- that TPC addresses FAO with the need to support programmes in intensive reforeta- tion, to alert public awareness to this problem and its solution, and to emphasize the role which fast growing trees, such as Salicaceae, can play in this urgent major effort.
Populus euphratica
In view of the interest for Populus euphratica for the benefit of people living in semi-arid and arid areas of the world, it is recommended to:
- invite all the Member States to cooperate with IPC in investigating the variability of this species in the various parts of the area of natural distribution
- invite the Member States concerned to take appropriate measures to manage and preserve the natural stands of this species;
- promote exchangeofseeds of various provenances and of good phenotypes in order to establish at least one "populetum euphraticum" in the near future.
