Abstract: A trial for development of suitable agronomic practices was laid down in split plot design (SPD) under irrigation and rainfed conditions of Jodhpur, Rajasthan. It was conducted in optimum spacing with four levels of irrigation (0, 10, 20 and 30 days) and four levels of Farm Yard Manure (FYM) with five important medicinal plants viz. Aloe vera (L.) Burm.f.(Guarpatha), Asparagus racemosus Willd. (Satavari), Catharanthus roseus (L.) G.Don. (Sadabahar), Ocimum sanctum (L.) (Tulsi) and Withania somnifera (L.) Dunal (Ashwagandha). Aloe vera (L.) Burm.f. (Guarpatha) showed best growth at 40 x 40 cm spacing under irrigated condition (20 days interval) with application of 2 kg of FYM/m2. A.racemosus showed best growth at 50 cm x 50 cm spacing with the application of 10 days intervals irrigation schedule but FYM showed non significant effect over the biomass production. C.roseus, O.sanctum and W.somnifera has shown significantly higher gorwth at 50 cm x 50 cm spacing under irrigation at 10-days interval and application of FYM @ 2 kg of FYM/m2.

Abstract: Lantana camara Linn. is a noxious weed posing a serious threat to the ecology. It demands concrete efforts for its management. L.camara was evaluated for its pulp and paper making properties. Data on chemical constituents, fibre dimensions, unbleached, bleached yield and physical strength properties of pulp sheets were obtained. Parameters of proximate chemicals and fibre morphology were non-significantly different for samples and replications (? = 0.05). The unbleached pulp yields under different pulping process were 50.5-44.6%. Laboratory hand made pulp sheets with adequate strength properties were obtained from soda, soda-sulphite and kraft pulps prepared from L.camara plant material.

Keywords: Pongamia pinnata (Karanj), Genetic divergence studies, Plus trees
Abstract: Thirty plus trees of Pongamia pinnata (Karanj) were selected and their progeny was tested in the nursery. Substantial variability was recorded in seed morphological and biochemical traits of selected plus trees. Significant variation was observed in progenies for germination percentage, shoot and root length, collar diameter and seedling biomass. Heritability and genetic advance as percent of mean were also moderate to high for 100 seed weight, oil and protein contents, collar diameter, root and shoot length indicating the effectiveness in selection for these characters for developing productive trees. Genetic diversity among these plus trees for important seed and seedling traits using Mahalanobis ' D2 analysis showed grouping of these trees into eight clusters. The clustering pattern indicated that geographical diversity did not have one to one relationship with genetic diversity. Cluster VI was the largest and consisted of seven trees followed by Clusters I and IV with six trees each.Cluster III had only one tree. Intra cluster D2 values revealed that cluster VIII was most diverse (5.423) followed by cluster IV (4.131), V (4.081), I (3.915) and cluster II (3.831). Maximum inter-cluster distance was observed between clusters III and VIII (9.922) followed by between cluster V and VIII (7.085), cluster IV and VIII (6.738) and cluster III and V (6.722). On the basis of high cluster mean and wide genetic distance, the superior plus trees of cluster III (PT-19) and cluster V (PT-8, Pt-18, PT -24) may be used as potential parents for P.pinnata tree improvement programme.

Abstract: Studies made with Jatropha curcas on seed priming with different growth regulators, temperatures and durations with the constant seed to solution ratio of 3:2 revealed that priming with IBA 200 ppm at ambient temperature for a duration of 12 to 24 h enhanced the quality characters of jatropha seedling raised at nursery to evaluate its performance in production of quality seedlings.

Keywords: Dalbergia sissoo Roxb., Age-age correlation models, Semi-arid region, Central India
Abstract: Nine years growth data of Dalbergia sissoo progeny trial established in semi-arid region of Central India was analysed. Significantly high age-age correlations were found for tree traits viz. height, dbh and D2H. Among three traits, empirical model developed for trait index D2H was found to be best fit (adj. R2 = 0.931). Using this model, the age-age correlations were predicted and efficiency of early selection in terms of gain per year for different plantation and rotation ages was estimates. For the selection age 12 years and rotation age 40 years, the genetic gain was almost twice. But this model is time dependent and does not take into account the growth rates. Another type of model based on variance ratio and a factor of relative size dependent growth was also applied. Predictions of age-age correlations were found to be better in case of D2H than height and dbh. According to this model, selection of progenies at 9 years age seems reasonably good for the improvement of height of Dalbergia sissoo.

Keywords: Epiphytes, Orchids, Bioindicators, Climate change, Conservation
Abstract: Of the diverse flora and fauna in an ecosystem, epiphytes in general and orchids in particular have a vital role to play in Mutualism. By virtue of their sensitivity to the changes in the climate they provide a forewarning about the impending damage due to these changes and act as bioindicators. Epiphytes constitute ten percent of the higher plants in tropical forest ecosystem. They provide a niche to many flora and fauna by complimenting the life supporting systems and play a vital role in rainforest hydrology and mineral cycle. Orchids as a group of epiphytes with 900 genera and 30,000 species are sensitive to variations in microclimate and are known as keystone species in the forest ecosystem. Interrelationship of orchids with various biotas in the ecosystem is well documented. Orchid ' s dependence on other biota and their co existence for several important processes such as pollination, dispersal and sustenance is well known. Natural and man made changes have influenced the climate and in turn the ecosystem through several of its parameters such as rainfall and temperature. One of the direct effects of this is, change in the plant structure and composition. The changes in the climate have also affected sensitive events such as flowering and pollination. This has forced the plant species to shift to more congenial climate for its survival and eventually affecting the coexisting biota. Therefore, before planning any conservation strategies the reasons for threat (especially manmade) to these indicator species must be understood. We believe that, ideal long term orchid conservation approaches must lay emphasis not only on the species but also on its fragile habitat.

Abstract: Physical and Mechanical properties of plantation grown Leucaena leucocephala obtained from Andhra Pradesh and F.R.I. Dehra Dun have been evaluated on the basis of tests done on small clear specimens in green and dry conditions. Suitability indices and Safe working stresses have also been calculated. It ' s grouping according to strength and classification for different end uses from strength point of view have also been done as per existing criteria. On the basis of strength, the timber is found suitable for structural use, door and window shutters/frames, furniture and cabinet making, flooring, tool handles, packing cases, dunnage pallets and expendable pallets etc.

Abstract: Forests provide a number of goods and services to the people. The dependence is very high especially amongst the tribals who live close to nature and collect food, fuelwood, timber, bamboos, medicinal plants and other non-wood products from the forests. However, with the increasing socio-economic standard of the people, their dependende on forests is gradually decreasing for certain goods and services. The present paper discusses the impact of development process and socio-economic scenario of ' Thadou-kukis ' on forests.
