dc.description.abstractThe present study deals with parameter that could influence early recruitment including germination and seedling growth with emphasis on the establishment of Quercus leucotrichophora in Garhwal Himalaya, because plant secondary compounds (terpenoides and or phenolic compounds) may direct competition. Other parameters like burying depth, light availability and root pruning could also influence seed germination and seedling growth. The present study was carried out during year 2014-15 in the research block of Department of Forestry, V.C.S.G. Uttrakhand University of Horticulture and Forestry, Ranichauri, Tehri Garhwal, Uttarakhand. Autotoxicity study in different plant part extracts concentration in laboratory and nursery, different depth in nursery, root pruning at different length from collar region in nursery were conducted to present study. Germination of seed under beneath of different canopy covers was also studied. In this experiment, germination %, mean germination time, germination index radical length were taken in laboratory while in nursery, germination %, mean germination time, germination index, different growth attributes and biomass estimation was done by giving different plant part extract treatments. In natural forest seed was sowed under different canopy cover. The result revealed that seed germination was not varied by different plant part extract treatments. But growth and biomass allocation were higher in plant part extract concentration as compared to control. Result on seed burying at different depth seed germination, growth attributes and biomass allocation were maximum in seed buried at shallower depth and minimum at deeper depth. In root pruning treatment, root pruned at 7 cm length from collar region shows maximum biomass allocations and more growth performance than severe root pruning and control. Light intensity having profound effect on seed germination. Hence present study showed that different parameter viz, autotoxicity, burying depth, root pruning and light availability could influence seed germination and growth of Q. leucotrichophora.en_US
