摘要：

A polymorphism in rice amylases at an early stage of seed germination is analyzed by zymogram, In nonglutinous cultivars of rite, alpha -amylase isozymes are mainly confirmed in germinating seeds. However, in glutinous cultivars, beta -amylase isozymes, which are not confirmed in nonglutinous cultivars, make up the major part of the total amylase activity and the expression of alpha -amylases are repressed.
