毛竹成竹过程中内源激素动态变化
Dynamic Changes of Endogenesis Hormone in Bambooformation Course (Phyllostachys edulis)
摘要
Abstract
The changes in the content of endogenous phytohormones of Phyllostachys edulis during the bamboo shoot and bamboo formation stages were determined by HPLC. The results showed that the contents of both ZT and GA3 increased with the growth of bamboo shoot. The parts ordered by the content ((μg/g, measured by fresh weight) of ZT in bamboo shoot were;stump root (5.66 μg/g) > middle part, basal part, and stump (1. 83-2. 20 μg/g) > shoot vagina, distal part (0. 77 , 0. 96 μg/g respectively). The GA3 contents of shoot vagina, middle part, basal part, stump, stump root were between 22. 40-28. 09 μg/g, but that of distal part was 14.67 μg/g. ZT, 6-BA, 2-ip, GA3, ABA and IBA were detected in the bambooformation course, but there was no IBA in leaf and culm. On the whole, the max content of endogenous phytohormones was founded in leaf, and then branch, root and culm, the content of hormones in stump was the lowest. In culm during the bambooformation course in, the content of GA3 decreased towards the lower positions. ZT,2-ip and 6-BA decreased rapidly in culm distal part, and lightly in both middle and basal parts. But the contents of ABA were the lowest comparatively at all positions of culm.关键词
