Abstract

Leaf Relative Water Content (LRWC) and biomass production were estimated at monthly intervals in seven deciduous forest tree species for a period of one year starting from June, 1990 to May, 1991. The leaves of all the seven tree species showed significantly higher leaf relative water content during winter than in summer. Leaf relative water content showed marked seasonal variations and these differed from one plant species to the other. A significant positive correlation (r² = 0.79) was found between leaf relative water content and biomass production in all the seven deciduous forest tree species studied. The results of the present study indicate that measurement of leaf relative water content could be used as simple screening method for selecting the right type of tree species for energy plantations.

Abstract

Seasonal changes in the growth rates of seven tree saplings were studied for a period of one year. Maximum leaf area, number of branches, stem girth, shoot and ischolar_main length were observed in the winter season in all the seven tree species. The growth rates showed month to month and species to species variations.

Abstract

Deoiled seed cakes of B. latifoila, P. glabra, A. indica and R. communis were applied as fertiliser to the saplings of Terminalia bellerica. The treatment of all the four deoiled seed cakes caused better growth response compared to that of control. Among the four deoiled seed cakes the best growth and biomass production was observed with B. latifolia seed oil cake.
