Abstract

Studies on protein fractionation in seed coat, embryo, cotyledons and whole seed were made to observe th e differences, if any, between chickpea and pigeonpea. Results indicated th a t globulin was the major fraction o f embryo and cotyledons o f these legumes. Seed-coat nitrogen was observed to be mostly comprised o f nonprotein nitrogen and glutelin fractions and thus differed from other components in both chickpea and pigeonpea. The albumin fraction o f cotyledons o f both crops had the highest concentration o f sulphur amino acids, methionine and cystine. Glutelin contained a considerably higher concentration o f methionine and cystine than did globulin in chickpea and pigeonpea. This suggests th a t lines with higher glutelin should be identified to improve their protein quality. The amino acid compositions o f different seed components did not show large differences between these two pulse crops.
