Abstract: Khair mortality was recorded in two central Indian states, Madhya Pradesh and Maharashtra. Mortality was observed in 9-20 years old plantations upto 93 per cent in both states due to root rot disease caused by a fungus, Ganoderma lucidum. In Madhya Pradesh, the worst affected areas are Palpur (Sheopur) and Ghuniya beet (Indore) having maximum 93% and 40% mortality respectively. In Maharashtra, Hiwari range of Yavatmal was found as the most affected site having upto 60% mortality respectively. In Maharastra, Hiwari range of Yavatmal was found as the most affected site having up to 60% mortality due to this disease. Fusarium sp. also causes 3% mortality in one year old plantation at Akoli beet, Pandherkawda (MS). Total 17 fungal species were found associated with different stages of khair mortality which include 6 fungi, namely Hapalopilus nidulans, Lenzites pisolotii, Monodictys castoneae, Resinicium bicolor, Rigidoporus vinctus and Trametes hirusita recorded for the first time from central India.

Keywords: J. curcas, Growth, Linear and non-linear regression, Seed yield equation.
Abstract: Jatropha curcas Linn. is considered as a promising source of bio-diesels since the plant grows well in semi-arid marginal soils and is fairly resistant to pests and diseases. The seed parameters are highly variable and the growth and yield are inter-related to each other. The yeild potential of seed is affected by many factors. The parameters like height, diameter, crown, age and density are good tools to predict the seed yield in J.curcas. Attempts have been made to develop models to predict the seed yield in Jatropha curcas. Both, the linear and non-linear equations were used to develop the model. However, linear models suffered with the problems of abnormal distribution and residual autocorrelation and hence non-linear model was found suitable to estimate the seed yield based on the age and growth parameters. The model developed is based on the dataset collected from two plantations at a particular location having density of 2500 plants/ha. For wider applicability of the model, larger dataset is required which should have data from different locations and from different planting densities and age groups.

Keywords: Jatropha curcas, Germination, Variation, Seed source, Heritability.
Abstract: Seed germination triats i.e. germination percent, germination value and germination energy in laboratory and nursery conditions were evaluated for 97 accessions of Jatropha curcas belonging to 10 stands in Uttarakhand. On the basis of all seed germination traits tree T1 of stand S8 were best. Stand S3, which was not the best stand of germination percentage on the basis of stand level analysis, had trees showing 86 percent laboratory germination on par with the trees having the highest germination percent (87.5%) in the study at tree level. High heritability (77%) and moderate genetic gain (21%) were recorded at stand level for germination percent at 5% selection intensity. The expression of germination traits was usually higher under laboratory than under nursery conditions. It was suggested that the collection of seeds for germination purpose should be done by taking individual tree as a unit rather than taking stand as unit of collection.

Abstract: Alpine timberline, considered to be important ecotone supports rich and highly vulnerable biodiversity and represent one of the most distinct boundaries between forest to tree less alpine areas. It has attracted geographers and ecologist to do research for a long time on th ohenomena it encompases. In recent time, alpine treeline ecotones across most of the world ' s mountains are being studied because of their potential for monitoring the effects of cimate warming on forest ecosystem. Besides, alpine pasture areas in and around timberline zone and commercially important medicinal plants along timberline have also been playing important role as a source of livelihood of mountain communities settled in nearby area. In recent time, with the change in socio-economic aspiration of local mountain communities there has been a rapid increase in pressure on natural resources in and around timberline area. However, compared to studies of timberline area of European Alps, Andes of South America and mountains of North America, which has reached a very advanced stage, very limited studies on timberline of Himalayan mountain range have been carried out. In the present paper, review of timberline research work carried out in the mountain ranges of Europe, North America and Himalaya have been carried out to highlight the gap in alpine timberline research work in Himalaya.

Abstract: The present study was carried out in broad leaved evergreen oak forests of Garhwal Himalaya, Uttarakhand, India (1500-2100 m amsl.) along disturbance gradient. In this study, some disturbance indicators i.e. canopy cover, stand density, grazing intensity, lopping intensity, number of cut stumps and climber invasion have been evaluated and with the help of these indicators the forest area has been categorized into three categories viz. undisturbed, moderately disturbed and highly disturbed. The study revealed that tree diversity decreased with increasing intensity of disturbance in case of tree and herb species but it was found maximum in moderately disturbed stands for both layers (tree, herb) whereas, in case of shrub species, Shannon diversity increased with increasing disturbance level. Simpson dominance index was found as reverse of the Shannon index in all three layers of vegetation for all disturbance categories. Almost same trend was found in species richness. It was found more vulnerable to disturbance in case of tree and herb layers as it decreased with increasing level of disturbance but its highest values were recorded in the moderately disturbed stands in both vegetation layers. On the other hand shrub species richness favored the disturbance has increased with increasing intensity of disturbance. As far as the regeneration is concerned, sapling and seedling density was decreased with increasing disturbance level but both the classes were found maximum in the intermediate level of disturbance. Diameter-density curves depicted a successive reduction in the number of trees from lower girth classes to upper. All the above variations in relation to species richness, distribution pattern and regeneration potential are related to anthropogenic interference.
