'ROC16' and 'ROC22' which are shy-flowering under nature conditions were used as experimental materials. Changes of carbohydrate and soluble protein of the leaf induced by photoperiod in the process of sugarcane flower bud differentiation and flowering reversion were studied. The results showed that the contents of soluble total sugar, starch and protein were without apparent changes after induced by photoperiod compared with control before differentiation. But from flowering induced period, the contents of soluble total sugar, starch and protein were increased rapidly, significantly higher than the control. As the further development of flower bud differentiation, the contents of total soluble sugar and starch reduced gradually, even lower than the control, still at a low level, while the contents of soluble protein were always higher than the control. The contents of soluble total sugar, starch and protein of the leaf flowering reversion in the early period of flower bud differentiation were all higher than the control, but lower than the normal flowering plants. As the flower bud differentiation stop, the contents of soluble total sugar and starch still retained stable level, only protein slightly reduced. The experiment showed that the process of gene expression and protein synthesis in the sugarcane flower bud differentiation period needed to consume a lot of carbohydrates.
