摘  要:
The key metabolism factors for bloom of Phyllostachys heteroclada olive and Neosinocalamus affinis Keng were analyzed by using the principal component analysis method.The results showed that GA_3,GA_3/ABA and starch were the most important factors related to bloom of the two bamboo species,followed by soluble sugar,activities of starch enzyme and glutaminase.GA_3,starch and soluble sugar with a certain content,and GA/ABA were positively correlated to the bamboo blossom.However,ZT,ZT/ABA and starch enzyme activity had a clear link to bamboo flowering reversion of Phyllostachys heteroclada.In order to know bamboo flowering more clearly,a preliminary simulating model of bamboo flowering was constructed.The model shows that the bamboo flowering procedure is lengthy and complicated.Any influence and break in the procedure would probably accelerate or terminate growth and florescence course,which could be the reason why bamboo florescence is so variable.
