本文进行了不同栽培地区几个不同品种油橄榄花芽形态分化及其与气候条件和新梢生长关系的探讨。研究认为,油橄榄花芽分化具有高度的时间集中性;温度是影响花芽分化的主导气候因素,花芽分化起始的界限温度为旬平均7—9℃,最适温度为10—15℃,并推断油橄榄花芽生理分化依赖于冬季一定程度的低温积累;不同年度及地区花芽分化在时间上的变化集中反映了温度变化这一本质;油橄榄花芽分化与新梢生长在时间上的顺序关系是树体内部营养物质调节分配的主要形式之一。
In this paper, the morphological differentiation of flower buds of several different cultivars in different cultivated areas and their relationship with climatic conditions and shoot growth were discussed. The results show that the flower bud differentiation of Olive is highly time-concentration. Temperature is the dominant climatic factor that affects flower bud differentiation. The starting temperature of flower bud differentiation is about 7-9 ℃ in ten days and the optimum temperature is 10-15 ℃, Physiological differentiation of flower buds depended on a certain degree of low temperature accumulation in winter. The temporal change of flower bud differentiation in different years and regions reflected the essence of temperature change. The temporal order of flower bud differentiation and shoot growth was the internal nutrition of tree Material regulation and distribution of one of the main forms.
