Effects of accelerated ageing on viability, leachate exudation, and fatty acid content of Dalbergia sissoo Roxb

Abstract

Accelerated ageing of seeds of Dalbergia sissoo Roxb., a multi-purpose tropical legume tree, was effective as a vigour test only at temperatures in excess of 43 deg C for 72 h. Increased leakage of solutes accompanied the decrease in viability, but there was no relationship between seed size and conductivity. Analyses of D. sissoo lipids indicated that palmitic acid was the most common saturated fatty acid and linoleic acid the most common unsaturated fatty acid. While total percentages of saturated and unsaturated fatty acids varied little throughout the course of the experiment, quantities of all individual fatty acids decreased during the ageing process
