Changes in a-amylase activity, during germination of the rice
grain, are presented in Fig. 4. The activity of a-amylase, of both
GBR and GRR, showed a steady increase, with advancement of
the germination time, for up to 72 h germination time and subsequently
it reached the maximum value of 21.0 and 42.5 U/g DM, in
GBR and GRR, respectively, after 96 h germination time.
