| The changes of starch content, accumulation rate and related enzyme activity of rice variety Feiyou188 with high amylose content were investigated. The results showed that highly significant differences were existed among the contents of amylase, amylopectin, total starch and the enzyme activity in Feiyou188 after flowering in each period.Accumulation pattern of amylose and amylopectin was similar, accorded with the Logistic curve equation amylose and amylopectin accumulation speed changing with the time was similar too, and both had very significantly positive correlation with the starch synthase activity. |
