Abstract Results pertaining to the germination percentage of pre-soaked seeds in a series of temperature regimes viz., 100C, 150C, 200C and 250C have revealed significant increase among seed sources in each of the three conifer species of Garhwal Himalaya. Soaking of the seeds for 24 hours in GA3 solution had shown maximum germination in A. pindrow (45.0±4.19%), C. torulosa (57.0±3.40%) and P. smithiana (56±6.01%) as compared to untreated (control) seeds. It has also been observed that GA3 treatment caused an appreciable shortening of the germination period by 10 days. Therefore, seeds of these commercially important tree species should be pre-treated particularly with GA3 for 24 hours for getting enhanced germination. It is important to point out here that the seeds of each of the three species reflect poor germination in nature due to snow cover, seed decay, prevalence of excess water and lack of maintenance, however, because of increasing demand for large quantities of tree seeds for reforestation programmes, pre-sowing treatments are useful to improve the rate and percentage of germination. -

Variation in Soil CO2 Efflux in Pinus Wallichiana and Abies Pindrow

Soil CO2 efflux was found maximum in July and minimum in December in both the forest types. Significantly (P<0.001) greater soil CO2 efflux was measured inPinus wallichiana forest compared to Abies pindrow forest throughout the study period. The -2 -1 range of soil CO2 efflux (mg CO2 m hr ) from the soil was 126-427 in Abies pindrow forest and 182-646 in Pinus wallichiana forest. Soil CO2 efflux showed greater values in Pinus wallichiana forest than Abies pindrow forest, which could be attributed to greater tree density, tree biomass, shrub density, shrub biomass, forest floor litter and moisture. Soil CO2 efflux also showed significant positive relationship with air temperature. In addition to that the altitudinal difference may be one of the reasons for variation in soil CO2 efflux between the two forest types. This result also indicates that at higher altitude even a small difference in elevation (100 m) alter the functional attributes of the ecosystem. -

IUCN Red List of Threatened Species™ to Identify the Level of Threat to Plants
Ex-Situ Conservation at Scott Arboretum Public gardens and arboreta are more than just pretty places. They serve as an insurance policy for the future through their well managed ex situ collections. Ex situ conservation focuses on safeguarding species by keeping them in places such as seed banks or living collections. In situ means "on site", so in situ conservation is the conservation of species diversity within normal and natural habitats and ecosystems. The Scott Arboretum is a member of Botanical Gardens Conservation International (BGCI), which works with botanic gardens around the world and other conservation partners to secure plant diversity for the benefit of people and the planet. The aim of BGCI is to ensure that threatened species are secure in botanic garden collections as an insurance policy against loss in the wild. Their work encompasses supporting botanic garden development where this is needed and addressing capacity building needs. They support ex situ conservation for priority species, with a focus on linking ex situ conservation with species conservation in natural habitats and they work with botanic gardens on the development and implementation of habitat restoration and education projects. BGCI uses the IUCN Red List of Threatened Species™ to identify the level of threat to plants. In-depth analyses of the data contained in the IUCN, the International Union for Conservation of Nature, Red List are published periodically (usually at least once every four years). The results from the analysis of the data contained in the 2008 update of the IUCN Red List are published in The 2008 Review of the IUCN Red List of Threatened Species; see www.iucn.org/redlist for further details. -

Sarwar*, A.N. Khalid, M. Hanif & A.R. Niazi Department of Botany, University of the Punjab, Quaid-e-Azam Campus, Lahore, 54590, Pakistan * Correspondence to: [email protected] Abstract — Suillus flavidus (Boletales, Suillaceae) was found associated with Pinus wallichiana during a survey of macrofungi from moist coniferous forests of Pakistan. Both the fruiting body and ectomycorrhizae were characterized morpho-anatomically as well as by molecular analysis. This fungus is a new record for Pakistan and its ectomycorrhizae with Pinus wallichiana are described for the first time by molecular analysis. Key words —boletes, ITS, mantle, PCR, rDNA Introduction Coniferous forests of Pakistan are located at an elevation of 1373 to 3050 m a.s.l. and are characterized by luxuriant growth of trees such as Abies pindrow, Cedrus deodara, Picea smithiana, Pinus roxburghii, P. wallichiana, and Taxus wallichiana. Among these conifers, some deciduous trees and shrubs of different species also occur (Hussain 1995). Another important feature of these forests is the high level of rainfall during summer (July–August). High rainfall and temperature make an environment suitable for the growth of mushrooms. Most of these fungi form mutualistic symbiotic associations with forest trees in the form of ectomycorrhizae that facilitate tree growth through enhanced nutrient absorption and protection of roots from root pathogens (Marx 1991).

The elevation ranges from 1500m to 3000m with a rainfall from 400mm to 800mm. The forest consist of mixture of evergreen Pinus wallichiana, Cedrus deodara, Abies pindrow and Picea smithiana with little admixture of broadleaved trees. All these species are capable of attaining good height (27-35m), very considerable girth (44-48cm). Stem and crown parameters were measured for 2880 trees between 2000- 2700m altitude. DBH and BA increased with increase in elevation while tree height, crown length, crown surface area, crown volume and tree density decreased as elevation increased. Species specific behavior and changing pattern of canopy attributes in relation to altitude in these forests are discussed. * Corresponding Author: Muhammad Hashim [email protected] 317 Hashim and Dasti Int.

Tree-Ring Chronologies of Picea Smithiana (Wall.) Boiss., and Its Quantitative Vegetational Description from Himalayan Range of Pakistan
Pak. J. Bot., 37(3): 697-707, 2005. TREE-RING CHRONOLOGIES OF PICEA SMITHIANA (WALL.) BOISS., AND ITS QUANTITATIVE VEGETATIONAL DESCRIPTION FROM HIMALAYAN RANGE OF PAKISTAN MOINUDDIN AHMED AND SYED HUMAIR NAQVI Department of Botany, Federal Urdu University of Arts, Science and Technology, Gulshan-e-Iqbal Campus, University Road, Karachi. 75270, Pakistan. Abstract Modern Dendrochronological techniques were used in 5 stands of moist temperate and dry temperate areas in Pakistan. Out of 91 cores from 60 trees of Picea smithiana (Wall.) Boiss., sampled where cross dating was possible among 48 cores. Dated chronologies from 1422 to 1987 AD were obtained. However, common period of all chronologies 1770 to 1850 A.D. is presented. Chronologies and sample statistics are described. These chronologies show from 17% to 33% variance (“Y” in ANOVA) due to climate. Dry temperate sites show low autocorrelation as compared to moist temperate sites. Due to small sample size, no statistical correlation was observed between community and dendrochronological attributes. However, community attributes gave some idea to select better sites for dendrochronological investigations. It is suggested that despite difference in climatic zones and chronologies, trees show some similar pattern of ring-width. Hence, Picea smithiana (Wall.) Boiss., could be used for dendroclimatological investigations. It is also suggested that detailed sampling is required to present strong database. Introduction Ahmed (1987, 1989) explained the scope of dendrochronology in Pakistan, and mentioned suitable sites and tree species, which could be used in tree-ring analysis. He also presented modern tree-ring chronologies of Abies pindrow Royle from Himalayan region of Pakistan. A dendrochronological approach to estimate age and growth pattern of various species and dendrochronological potential of a few tree species from the Himalayan region of Pakistan was described by Ahmed & Sarangezai (1991, 1992). -
