Abstract
Neem seeds of seven provenances from different agroclimatic zones of Orissa were collected from plus trees and their physical parameters like seed length, width, thickness, weight and moisture content were determined. Germination per cent of seeds in sand, germination paper (in laboratory), mother beds and polybags (in nursery) were also recorded. All these traits were correlated with each other and also with latitude and longitude of agroclimatic zones. Seed thickness and seed weight of neem showed a large variation among different provenances and significant relationship with germination behaviour of seeds under nursery conditions. Bhubneshwar and Sambalpur provenances showed their superiority over other provenances of Orissa.
