Biochemical changes in developing seeds of pigeonpea (Cajanus cajan)

Contents of soluble sugars, starch, soluble N and protein N were studied in developing seeds of 3 cv. of pigeon pea. When expressed on a /seed basis, soluble sugars increased up to 35 days after flowering and then declined slightly. Rapid starch accumulation was observed between 14 and 28 days after flowering. The levels of soluble N and protein N underwent rapid changes during the same period. Amino acid composition of seed protein was studied at different stages of maturation. Sodium dodecyl sulphate polyacrylamide gel electrophoresis of salt-soluble proteins revealed that seed storage globulins were formed after 14 days of flowering and did not change much during later stages of maturatio
