影响果树产量最重要的原因之一是花芽的形成。每种果树花芽的分化和形成各有其特点。苹果、梨和杏树等这些果树的花芽分化均在夏季。通常,花芽的组织原基在冬季形成,经过冬季休眠之后,随着气温增高,生长环境的改善,花芽组织逐渐发育、开花。如果花芽组织未得到足够的冬季低温过程,其花芽就会败育。油橄榄花芽,通常在2～3月分化,随着短日照向长日照过渡,油橄榄树于5月或6月开花。许多研究者已注意到油橄榄花芽形成的
One of the most important causes of fruit tree yield is the formation of flower buds. Each fruit flower bud differentiation and formation have their own characteristics. The flower buds of apple, pear and almond trees are all in summer. Normally, flower bud tissue primordium is formed in winter. After winter dormancy, flower bud tissue gradually develops and blooms as the temperature increases and the growth environment improves. If the flower bud tissue is not enough winter low temperature process, its flower buds will be aborted. Olive buds, usually in February to March differentiation, with the short-day transition to the long sun, olive tree in May or June flowering. Many researchers have noticed the formation of flower buds of olive
