Degradation of storage proteins and formation of endopeptidases in precociously germinating peanut embryos


, : Degradation of storage proteins and formation of endopeptidases in precociously germinating peanut embryos. Proceedings of the Fourth International Workshop on Seeds: basic and applied aspects of seed biology, Angers, France, 20-24 July, 1992 Volume 2: 345-350

After removal of the seed coat, the immature embryos of groundnut Shanyu 71 germinated and reached 98% germination at 40 days after planting (DAP). Benzoylarginine-p-nitroanilide hydrolysing enzyme activity in the cotyledons of 60 DAP embryos increased and had 2 activity peaks after precocious germination. Endopeptidase (gelatin hydrolytic enzyme) activity in the embryos appeared at 1 d after precocious germination. The embryos began to degrade storage protein rapidly at 2 d after germination.

Endopeptidase activity in high vigour groundnut seeds increased rapidly from the 2nd to the 4th day after imbibition, while activity in medium vigour seeds increased more slowly.
