Biochemical changes in the seed during germination


, : Biochemical changes in the seed during germination. International Rice Research Institute Annual Report 1970: 18-20

During the 1st week of germination, changes in the levels of substrates and enzymes of the endosperm of IR8 were generally more rapid in the dark than in the light in seeds germinated at 30 deg C. In diffuse light, starch content decreased, especially at 6 days after germination, and was accompanied by an increase in free sugars content. The activities of R-enzyme, alpha -amylase and beta -amylase were initially low but increased within 3-4 days.
