EFFECT OF SEED SIZE ON SEED GERMINATION AND VIGOUR IN <em>PONGAMIA</em> <em>PINNATA</em>

Abstract

Studies carried out to investigate the influence of three different seed sizes on germination and vigour in Pongamia pinnata revealed large seeds to be characterised by better germination and vigour index. A linear relationship between seed size and quality attributes was also discernible. Seed size, however, had no bearing on either germinability or vigour under storage. In general, seed deterioration set in at the end of three months and therefore the seeds can be stored well for only two months.
