柑桔的产量是由果实数与单果重构成,而果实是由花芽发育而来,这就表明花芽分化的多少和质量的高低直接关联着当年的产量,同时又与次年的产量紧密相关。对果树花芽分化的认识,目前也有较多的报道认为,从控制花的发生机理来看,在树体内有一定营养物质基础的前提下,花原基的发生与果树体内的激素有重要关系。关于赤霉素与柑桔花芽形成关系的研究,近年 The yield of citrus is composed of the number of fruit and single fruit, and the fruit is formed from the flower buds, indicating that the number and quality of flower bud differentiation is directly related to the current year’s output, but also with the next year’s production are closely related. Nowadays, there are more reports on the flower bud differentiation of fruit trees. From the view of controlling the mechanism of flower formation, the occurrence of flower primordium has an important relationship with the hormones in fruit trees under the premise that there is a certain nutrient in the tree. On the relationship between gibberellin and citrus flower bud formation in recent years
