Biochemical changes in developing seeds of pigeonpea ( Cajanus cajan)

Soluble sugars, starch, soluble nitrogen and protein nitrogen were studied in developing seeds of 3 cultivars of pigeonpea. When expressed on a per seed basis soluble sugars increased up to 35 days after flowering and then declined slightly. Rapid starch accumulation was observed between 14 and 28 d...

Summary:Soluble sugars, starch, soluble nitrogen and protein nitrogen were studied in developing seeds of 3 cultivars of pigeonpea. When expressed on a per 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 nitrogen and protein nitrogen underwent rapid changes during the same period. Amino-acid composition of seed protein was also studied at different stages of maturation. Sodium dodecyl sulphate polyacrylamide gel electrophoresis of salt-soluble proteins revealed that seed storage globulins are formed after 14 days of flowering and do not change much during later stages of maturation.
