The varieties have and will continue to be selected to satisfy the requirements of current gardens, with more gardeners looking for trees suitable for small to medium gardens. Look out for the recommendations for trees to plant in small, medium and large gardens at the end of this section. Primarily produced from budding and grafting, the three-year trees are produced in a 12 litre rigid container. With advanced husbandry techniques, our trees are produced to a full but compact specification with an overall height of 1.8 - 2.1 metres with side branches retained where appropriate.

Dietary profile of Rhinopithecus bieti and its socioecological implications Abstract To enhance our understanding of dietary adaptations and socioecological correlates in colobines, we conducted a 20-mo study of a wild group of Rhinopithecus bieti (Yunnan snub-nosed monkeys) in the montane Samage Forest. This forest supports a patchwork of evergreen broadleaved, evergreen coniferous, and mixed deciduous broadleaved/ coniferous forest assemblages with a total of 80 tree species in 23 families. The most common plant families by basal area are the predominantly evergreen Pinaceae and Fagaceae, comprising 69% of the total tree biomass.

Non-specific Lipid Transfer Proteins (nsLTPs) are widely distributed in the plant kingdom and constitute a superfamily of related proteins. More than 800 different sequences have been characterized so far, but their biological functions remain unclear. It has been clear for years that they present a certain interest for agronomic and nutritional issues. Deciphering their functions means collecting and analyzing a variety of data from gene sequence to protein structure, from cellular localization to the physiological role. As a huge and growing number of new protein sequences are available nowadays, extracting meaningful knowledge from sequence-structure-function relationships calls for the development of new tools and approaches. As nsLTPs show high evolutionary divergence, but a conserved common right-handed superhelix structural fold, and as they are involved in a large number of key roles in plant development and defense, they are a stimulating case study for validating such an approach. Methods. In this study, we comprehensively investigated 797 nsLTP protein sequences, including a phylogenetic analysis on canonical protein sequences, three-dimensional (3D) structure modeling and functional annotation using several well-established bioinformatics programs.

    Plant Introduction, Distribution, and Survival: a Case Study of the 1980 Sino-American Botanical Expedition

    03 June Forum Dossman 5/13/03 2:58 PM Page 2 Forum Plant Introduction, Distribution, and Survival: A Case Study of the 1980 Sino-American Botanical Expedition MICHAEL DOSMANN AND PETER DEL TREDICI The 1980 Sino-American Botanical Expedition (SABE) to the Shennongjia Forest District, Hubei Province, China, was the first botanical collect- ing trip by American scientists to that country since 1949. It was significant because the area visited had high species diversity and because the col- lected germplasm was widely distributed to a variety of botanical institutions throughout North America and Europe. This report documents the survival of this germplasm after 22 years of cultivation. Of the original 621 SABE collections, 258 are represented by plants growing in at least 18 different botanical institutions. The fact that 115 of these collections (45 percent) are represented by a single accession growing in a single location suggests that the plant introduction process is much more tenuous than has been generally assumed. This study also highlights the importance of data sharing among botanical institutions as the most effective way of determining the uniqueness of a given collection and assessing its environ- mental adaptability or invasiveness, or both, over a broad range.

    Traditional Knowledge and Its Transmission of Wild Edibles Used

    Geng et al. Journal of Ethnobiology and Ethnomedicine (2016) 12:10 DOI 10.1186/s13002-016-0082-2 RESEARCH Open Access Traditional knowledge and its transmission of wild edibles used by the Naxi in Baidi Village, northwest Yunnan province Yanfei Geng1,2, Yu Zhang1, Sailesh Ranjitkar1,3, Huyin Huai4 and Yuhua Wang1* Abstract Background: The collection and consumption of wild edibles is an important part in livelihood strategies throughout the world. There is an urgent need to document and safeguard the wild food knowledge, especially in remote areas. The aims of this study are to accomplish detailed investigation of wild edibles used by the Naxi in Baidi village and evaluate them to identify innovative organic food products. Also, we aim to explore the characteristics of distribution and transmission of the traditional knowledge (TK) on wild edibles among the Naxi. Methods: Data was collected through a semi-structured interview of key informants above the age of 20 years, chosen carefully by a snowball sampling. The interviews were supplemented by free lists and participatory observation methods. Informants below 20 years were interviewed to test their knowledge of traditional practices. A quantitative index like Cultural Importance Index (CI) was used to evaluate the relative importance of the different wild edibles. Linear regression and t-test were performed to test variation in the TK among the informants of different age groups and genders. Results: Altogether 173 wild edible plant species belonging to 76 families and 139 genera were recorded in the study. Cardamine macrophylla, C. tangutorum and Eutrema yunnanense, have traditionally been consumed as an important supplement to the diet, particularly during food shortages as wild vegetables.

  • Tree Planting and Management

    Tree Planting and Management

    COMMONWEALTH WAR GRAVES COMMISSION Tree Planting and Management Breadth of Opportunity The spread of the Commission's responsibilities over some 148 countries in temperate, mediterranean, tropical and desert climates provides wonderful opportunities to experiment with nature's wealth of tree species. We are particularly fortunate in being able to grow many interesting and beautiful trees and we will explain how we manage them and what splendid specimens they can make. Why Plant Trees? Trees are planted for a variety of reasons: their amenity value, leaf shape and size, flowers, fruit, habit, form, bark, landscape value, shelter or screening, backcloth planting, shade, noise and pollution reduction, soil stabilisation and to encourage wild life. Often we plant trees solely for their amenity value. That is, the beauty of the tree itself. This can be from the leaves such as those in Robinia pseudoacacia 'Frisia', the flowers in the tropical tree Tabebuia or Albizia, the crimson stems of the sealing wax palm (Cyrtostachys renda), or the fruit as in Magnolia grandiflora. above: Sealing wax palms at Taiping War Cemetery, Malaysia with insert of the fruit of Magnolia grandiflora Selection Generally speaking the form of the left: The tropical tree Tabebuia tree is very often a major contributing factor and this, together with a sound knowledge of below: Flowers of the tropical the situation in which the tree is to tree Albizia julibrissin be grown, guides the decision to the best choice of species. Exposure is a major limitation to the free choice of species in northern Europe especially and trees such as Sorbus, Betula, Tilia, Fraxinus, Crataegus and fastigiate yews play an important role in any landscape design where the elements are seriously against a wider selection.

    (Prunus Subgenus Cerasus) Cultivars Using Nuclear SSR Markers

Therefore, we evaluated the clonal status of 215 des- ignated cultivars using 17 SSR markers. More than half the cultivars were morphologically distinct and had unique genotypes. However, 22 cultivars were found to consist of multiple clones, which probably originate from the chance seedlings, suggesting that their unique characteristics have not been maintained through propagation by grafting alone. We also identified 23 groups consisting of two or more cultivars with identical genotypes. Most members of these groups were putatively synonymously related and morphologically iden- tical. However, some of them were probably derived from bud sport mutants and had distinct morphologies.
