雌花芽形态分化起源芽内雏梢,于6月中旬至7月上旬(中短枝停长后4一10周)开始至次年开花,整个发育过程约需十个月,从芽的外部形态变化可直观地判断雌花芽分化时期;通过栽培措施调节使分化提前和增加芽内雏梢节数,可提高雌花芽质量。雄花芽形态分化源于先年母芽雏梢分化期之后在叶腋出现的侧芽原基,4月上旬至翌年4月中旬性细胞形成历时约一年左右;雄花芽分化和开花散粉对树体养分消耗过大,影响雌花芽分化和果实发育,可采用疏雄、秋季施采果肥、春施速效肥等栽培措施减少影响。雌先型品种的雌花芽分化较雄先型品种开始分化早,在各个时期的分化上雌先型品种始终领先于雄先型品种,而雄先型品种在雄花芽分化的各个时期上领先于雌先型品种。 Female flower buds form the differentiation of shoot buds in the shoots, from mid-June to early July (4 to 10 weeks after the short shoots to stop long) began to flowering the following year, the entire development process takes about 10 months, from the external shape of the bud Changes can be intuitively determine the female flower bud differentiation period; through the cultivation measures to advance the differentiation and increase the number of shoots in the shoots can improve the quality of female flower buds. The morphological differentiation of male flower buds originated from the primordia of lateral buds appearing in the leaf axils after the differentiation of the first bud of the female parent. The formation of the sex cells in early April to mid-April of the next year lasted for about one year. Male flower buds and flowering powder Consumption is too large, affecting the female flower bud differentiation and fruit development, can be used sparse male, fruiting manure applied in the fall, spring Shi fertilizer and other cultivation measures to reduce the impact of speed. The female flower bud differentiation of the female first type varieties began to differentiate earlier than that of the male first type varieties, and the female first type varieties always lead the male first type varieties at all stages of differentiation. However, the male first type varieties lead ahead of the male flower bud differentiation in each period Female first type.
