摘要
综述多效唑对果树生长的形态学效应、多效唑与赤霉素的关系、多效唑对其他内源激素的影响以及多效唑对果树生理的影响。多效唑在果树上的主要应用是控制枝梢生长,促进花芽分化,保(疏)花保(疏)果,改变采收期,提高果品质量,减少夏季修剪量,提高果树的抗旱及抗寒性。影响多效唑作用效果的主要因子有使用时期和方法,果树种类、品种、砧木和树龄,多效唑的浓度、剂量和使用次数,本文还说明了在使用多效唑时应注意的事项。
This paper reviews the growth of paclobutrazol on fruit morphology effect,the relationship between paclobutrazol and gibberellin,paclobutrazol on other endogenous hormones,as well as the effects of paclobutrazol on the physiological effects of fruit trees;paclobutrazol in the fruit-tree on the main applications are to keep shoot growth under control,to promote flower bud differentiation,flower and fruit thinning,and change the harvesting period,improve fruit quality and reduce the amount of summer pruning,fruit-tree improve drought and cold resistance;Impact paclobutrazol effect of the main factor has paclobutrazol use of time and ways,fruit type,variety,stock and age,paclobutrazol concentration,dose and frequency of use;and describe the use of paclobutrazol tips.My thesis comprensively recounts the work mechanism of MET and it uses in the fruit tree,On the other hand,I'll analyse and discuss the main factors which affect its effects and explain something we should pay attention to when using it.
