Abstract

This paper presents the results of an investigation carried out for the effect of temperature and seed dessication on seed germination and seedling growth of Pinus patula. The result revealed that the maximum seed germination occurred under 3O°C. The low shade level and high moisture levels provided best growth to Pinus patula seedlings. The ischolar_main:shoot ratio was high at intermediate shade level.

Abstract

A quantitative analysis of woody vegetation in 12 stands of four aspects within an elevational range of 2100-2700 m in Central Himalaya was made. Q. floribunda exhibited absolute dominance in all the aspects. R. arboreum; I. dipyrena and Q. semecarpifolia were major associates. The total tree basal area ranged from 3898 to 5733 cm²/100 m² and diversity and concentration of dominance of total vegetation from 2.180 to 2.649 and 0.014 to 0.155, respectively.

Abstract

Litter biomass interception by different forest ecosystems in Central Himalaya was assessed during the 1982 monsoon season. Average litter biomass varied from 6.2 to 7.1 t ha^-1 and the litter interception renged in between 7.9 to 11.8% of gross rainfall among the sites. The broadleaf species intercepted greater amount of rain water compared to the conifers.
