Abstract

A total of eight provenances of Azadirachta indica A. Juss. collected from the different agro-climatic regions of peninsular India comprising of the states of Kerala, Tamil Nadu and Karnataka were evaluated for their seed and seedling characters.

Significant variations were observed for their seed characters, namely, hundred seed weight, seed length, seed length breadth ratio, thickness of pericarp and germination percentage. For the seedling characters studied, the maximum height and leaf number were observed for Coimbatore (Tamil Nadu) at both the growth phases of 180 and 360 DAS. The shoot root ratio was maximum for Palakkad (Kerala) and root length for Dindigul (Tamil Nadu). The study indicates that Coimbatore provenance can be considered as the most suitable seed source for planting neem in the agro-climatic conditions prevailing in the present experimental area.
