摘要
分析了‘丰水’梨去叶后二次开花过程中3种内源多胺的动态变化,结果表明,无论是在枝皮还是花芽,3种内源多胺在去叶后第6天迅猛上升,而后呈下降趋势;但枝皮中内源多胺直线下降,而花芽中内源多胺含量平缓降低,说明去叶对枝皮内源多胺的含量影响较大。‘丰水’梨花芽萌芽率与亚精胺含量呈极显著的正相关关系,与腐胺和精胺含量呈显著的正相关关系。
The Put,Spd and Spm contents in branches and buds of ‘Hosui＇were identified by HPLC analysis during reflorescence. The Put,Spd and Spm contents rose sharply and the content of Spm was the highest at 6 d and then decreased constantly. Three hormones were greatly infected by the defoliation in branches and floral bud. The result of correlation analysis was as follows： the reflorescence and polyamines appeared almost at the same time. The analysis of coefficients showed that the related coefficients for budding rate and three polyamines were 0. 834- 0. 902,reached at the 1 % significant level,and polyamines play a central role in dormancy controlling.
