Abstract: Sal (Shorea robusta Gaertn. f.) is a dominant tree species, whose natural range lies between 20-320N lat. and 75-950E long., is spread across 10 million ha in India. Species distribution models predict the species geographic ranges from occurrence records and site-specific environmental daa. Here, we have (i) generated the 1960s scenario for sal species on the basis of the existing published literature; (ii) confirmed the species occurrence data using satellite imagery for the period of 1972- 75; (iii) run the Maxent species distribution model to predict the distribution for the year 2020 under climate change scenario SRES A1-B and (iv) validated the prediction using more than double the amount of species occurrence data gathered during the last decade (1998-2008). The model identified moisture as the key player that would influence the distribution to shift towards northern and eastern India, with greater than 90% certainty. The study highlights utility of the archived remote sensing data in providing locational information in climate change studies.

Abstract: Subabool [Leucaena leucocephala (lam) Dewit] play an important role in agroforestry system, which provides a way to sustan agricultural production under rising land pressure and worsening soil degradation conditions. It has unique properties and suitable for growing as hedgerows with other crops. It also carriers important functions of a traditional bush fallow for nutrient recycling, sources of green manure, firewood and staking material. Addition of Leuceanae pruned material increases total soil nitrogen and organic carbon . But consistent and considerable reduciton in yield of associated field crops upto a level of 30-90% was observed when sown as sole and mixed in alley cropping system but these losses of yield can be compensated by an additional yield obtained from Leucaena biomass. This reduction in yield of crops is due to hedgerow species in alley cropping competition with companion crops for available light, water and nutrients. Besides, Subabool supplies a good quality of feed to all kinds of animals because it contains high amount of protein, has good palatability and ability to withstand repeated defoliation. Moreover, its fodder is particularly useful for goats in the tropics as they can degrade to a great extent, even toxic amino acid (mimosine) present in Leucaena plant can be utilized by goats with out any adverse effect. The fodder available from this tree can also be fed to cow, camel. buffalo and sheep to limited extent because continuous feeding to animals may cause metabolic disorder

Abstract: A study was conducted to estimate the biomass production and nutrient removal by eight years old poplar plantation raised at different spacign in a rreplicated randomized block design having three spacing of 5 x 4 m, 10 x 2.5 m and 15 x 2.5 m. Biomass of all the plant parts decreased with increasing tree spacing except that the differences between 10 x 2.5 m and 15 x 2.5 m spacing in respect of leaves and branches biomass were not significant. The total tree biomass including litter fall was higher in 5 x 4 m (415 t/ha) followed by 10 x 2.5 m (330 t/ha) and 15 x 2.5 m (192 t/ha) spacing. Concentration of both primary and secondary nutrients in different plant parts differd signifiantly at different spacing. Maximum nutrient concentration was recorded in leaves at 15 x 2.5 m spacing. However, poplar stem accounted for maximum uptake of all the nutrients. Among poplar spacing, closer tree spacing of 5 x 4 m recorded maximum uptake of both primary and secondary nutrients except that K and Mg uptake was maximum at 10 x 2.5 m spacing.

Keywords: Populus L, India, distribution, identification , leaf characters
Abstract: The genus Populus L, belongs to the family Salicaceae Mirb. having 35 species of worldwide distribution . In India, total 8 taxa are known mainly distributed throughout the Himalayas. Species like. P.alba L, P. balsamifera L, P. deltoides Bartram ex Marshall, P. euphratica Oliv. and P. nigra L. var. italica Du Roi are confined to the north-western parts of India while P. gamblei Dode and P. glauca Haines are found in the north-eastern parts. P. ciliata Wall. ex Royle is the most common species found both in the eastern as well s western Himalayas. Nature of the axillary buds and the terminal buds, number of valves in the capsules are the useful characters for identification of these species but one of the most important features is the leaf character through which one can easily identify the species in the field as well as while the species are in non-floriferous condition. The distribuiton pattern with two maps of these 8 species is discussed. An artificial key is provided along with illustrations of leaf characters for easy identity.

Abstract: Variability studies of twenty-three candidate plus trees of M. latifolia Macb. revealed significant difference among candidate plus trees for seed traits and germination capacity. CPT-5, CPT-16 and CPT-2 recorded highest for 100-seed weight (286.27 g), oil content (51.15%) and germination capacity (84.77%) respectively. The phenotypic and genotypic coefficients of variations were close to each other for all traits except germination capacity. Germination capacity exhibited positive significant correlation with 100-seed weight both at genotypic (r = 0.762) and phenotypic (r=0.548) level and seed weight expressed positive significant correlation with oil content both at genotypic (r=0.604) and phenotypic (r=0.573) level. In conclusion, oil content and 100- seed weight are under strong genetic contro hence improvement in these characters can bring improvement in germination capacity.

Abstract: Commerically important bamboo, Bambusa bambos (L.) Voss is the abundantly occurring in the forests of Kerala State in India. The average growing stock of B. bambos per ha in different stand density classes in the forests of Kerala was estimated through a statistically designed field survey in natural forests. The average number of culms per hectare ranges from 2741 in pure bamboo patches to 742 in poorly stocked bamboo areas. The estimated average green weight per ha is 147.8 metric tonnes in pure bamboo patches, 83.8 metric tonnes in medium density bamboo stands and 29.4 metric tonnes in areas with poor stocking. In terms of moisture free dry-matter content, the average oven-dry weight per hectare is 80.9 metric tonnes in pure bamboo patches, 45.9 metric tonnes in medium density bamboo stands and 16.1 metric tonnes in areas with poor stocking. the above estimates are useful for assessing the growing stock of bamboo in terms of either green weight or dry weight, when the area under bamboo in the forests in a region is known from field or aerial surveys.

Abstract: The study was conducted to determine the effect of IBA-chemical formulations and cutting types on rooting behaviour of Erythrina suberosa during monsoon and spring seasons. Cuttings set in spring exhibited overall better performance in all the rooting characteristics. Application of 0.6% IBA + 1% captan + 2% sucrose- talc significantly maximized sprouting, callusing, rooting and root characteristics (root number, root length and root dry weight). Cuttings of lateral type showed significantly better performance as compared to the terminal and sub- terminal ones. Maximum rooting (43.33%) and mean root dry weight (15.27 mg) were achieved wehn lateral cuttings were treated with 0.6% IBA + 1% captan + 2% sucrose- talc and planted in spring. The study also revealed that cuttings with higher levels of total phenol, total carbohydrate and C/N ratio and low level of nitrogen performed better.

Abstract: Approach to conserve biodiversity for sustainable development should be targetted at different levels, from improving living standards to changing the attitude of people. If Himalayan medicinal plants are to continue to serve the needs of the people without being reduced to a dangerously unstable resource base, they have to be considered in the perspective of sound ecological management that also has economic benefits to the local people. From the concept of in-situ conservation we need to move to In-situ cultivation.
