Abstract:
Fruits of Aisandra butyracea (Roxb.) Lamb. were collected from two sites located at different altitudes in Kumaun Himalaya for analyzing the seed maturity in relation to various fruit and seed characters. The mean seed size (length x width) across the collection dates varied between 186.44 +/- 0.05 and 238.17 +/- 0.5 mm2 across both the elevations. The fruit colour changed from dark green in the beginning to pale yellow on the maturity. The range of seed moisture content (62.83 +/- 1.33 to 63.46 +/- 0.89%) coincided with maximum germination. The colour change and seed moisture content appear to be the major indicators of seed maturation in A. butyracea.
