Biochemical changes in seeds of five cotton genotypes stored in different packaging materials at ambient condition

Abstract

Variation in the biochemical attributes of the seeds from five genotypes (CB-8, SR-08, BC-0125, BC-0236 and BC-0252) of cotton (Gossypium hirsutum L.) was appraised. Seeds were packed in polythene and cloth bag and stored over 14 months to determine the changes in biochemical composition under ambient condition. Results revealed that total soluble sugar, total soluble protein and oil content of cotton seeds decreased and total free amino acid increased with the increase of storage period. However, decreasing rate of total soluble sugar, total soluble protein and oil content and increasing rate of total free amino acid was slower in polythene bag and faster in cloth bag throughout the storing period. Among the genotypes, BC-0252 showed slower degradation of biochemical composition of stored seeds than that of seeds of other genotypes.
