摘要/Abstract

摘要： 利用灰色关联分析方法,通过试验研究了妃子笑和鹅蛋荔两个荔枝品种花芽分化期间气象因素对荔枝树体生理因素的影响、荔枝树体生理因素对花芽分化的影响以及气象因素对荔枝花芽分化的影响。结果表明:(1)对树体生理因素影响较大的气象因素主要是最小相对湿度、最低气温和平均相对湿度,对树体生理因素影响较小的是降水量、日照时数;(2)对荔枝花芽分化的影响较大的树体生理因素是结果母枝中ABA含量和IAA含量;(3)气象因素影响荔枝花芽分化的各因素中,最低气温对荔枝花芽分化影响最大,降水量对荔枝花芽分化影响最小。研究结果对荔枝花芽分化因素调控采取相关措施具有指导意义。

Abstract: By using the method of grey correlative analysis,the impacts of meteorological factors on trees' physiological factors,of trees' physiological factors to flower bud differentiation(FBD) and of meteorological factors to FBD of two litchi cultivars was analyzed.The results showed that(1)least relative humidity,minimum temperature and average relative humidity were more effective meteorological factors to litchi trees' physiology;(2)precipitation and sunshine duration were the less effective factors.ABA and IAA concentration in the litchi tresses were the larger effects trees' physiological factors to FBD;(3) minimum temperature was the largest factor to litchi FBD,and precipitation was the least of all the meteorological factors.The results provided an important theoretic basis for some scientific measures in improving litchi FBD.
