Abstract

Significant differences due to geographic variation were discernible in respect of germination, root growth, shoot elongation and vigour. Seeds collected from Coimbatore proved superior by possessing higher germinability and vigour index. Age of mother tree also had a bearing on seed vigour. Seeds collected from young trees of 2 to 3 years were characterised by poor germinability and low vigour. Those from old trees of 7 years also proved undesirable. Only those from trees aged 5 years possessed high germinability and vigour and collection of seeds from 5 year trees is therefore advocate.
