Bamboo is one of the fastest growing plants in world, but their shoot buds develop very slowly. Information about sugar storage and metabolism during growth lacking. In present study, we determined activity sucrose starch metabolizing enzymes developmental period Fargesia yunnanensis from to young culms that have achieved full height. The soluble sugars contents were also analyzed shoots at different stages. results showed there higher than shoots, which coincides with sweeter taste buds. As sprouted out ground, depleted sharply. Coupled this, acid invertase (SAI), cell wall‐bound (CWI), synthase cleavage direction (SUSYC) phosphorylase (STP) increased significantly rapidly elongating internodes. These dominated rapid elongation activities SAI, CWI, SUSYC STP adenosine diphosphate‐glucose pyrophosphorylase as compared other buds, far lower those developing shoots. slow was correlated low these enzymes. complement our understanding physiological differences between ascertain mechanism for bamboo
