Seed Maturity Indices in Spruce

Abstract

This study deals with seed maturity of spruce in relation to specific gravity of cones and seed moisture content. The specific gravity of mature cones varied from 0.97 to 0.99 and germination percentage of the seed collected from such cones varied from 47.2% to 50.4%. The moisture content of the seed decreased as the seed matured and the same of the mature seed varied from 20.97 to 22,12 per cent. The specific gravity of cones and the moisture content or the seed did not vary significantly with the elevation for the same dates of collection.
