Effect of Seed Origin on Coppice Regeneration in Diploknema Butyracea

Diploknema butyracea is a fast growlng species belonging to family Sapotaceae. It is multipurpose tree species with several uses including source of oil, fodder, fuel wood, timber and medicine. Source variation study of this species was undertaken to evaluate the sprouting ability. Fifteen sources sampled from different locations in Uttarakhand State were studied. Variation for most of the studied characters indicated non-clinical pattern. On the basis of this investigation, the population of Thali, Sail, Khitoli and Matela were found better in growth performance and in coppicing ability. The Thall population has shown the best growth (gain) performance for the purpose of vegetative multiplication garden to enhance the productivity.
