PANKAJ KAMTHAN

Abstract

Seed characteristics of tree spices common to dry deciduous mixed forest of Rajasthan have been studied. The bigger seed size and more weight in Pongamia pinnata, Terminalia tomentosa, Albizzia lebbek, Cassia fistula, Lagerstroemia parviflora, Dendrocalamus strictus, Dalbergia sissoo, Acacia catechu resulted in large amount of reserve food material foster to the growing embryo at the time of germination. Comparison to smaller seed size and lesser weight viz. Lagerstroemia parviflora and Terminalia tomentosa which show better help in dispersal with disadvantage of quantity of reserve food material and thickness of their wing in some categories of seeds.
