Abstract: The fluctuation of grain filling has tight correlation with enzyme status. The speed of grain filling usually is the maximum when the activity of most enzymes arrived its peak, which is about in 10 days after flowering. The smooth fluctuation of grain filling and long prophase and middle period lead to better rice quality, the better is about 14 days. The activity of ADP-glucose pyrophosphorylase was normally stabilizes in different varieties, which will arrive its peak about in 12 days after flowering. The fluctuation of Q-enzyme presents differently from others, which has no notable correlation with other enzymes.
