在深圳市，‘石硖’龙眼（Dimocarpus longanaLour.）“梢状芽”的生理分化期在12月中旬至翌年1月，花芽形态分化在1月下旬开始，2月上旬整个“梢状芽”进入花序发育期，2月底进入小花分化期.“梢状芽”的发育具可塑性，顶端与腋生分生组织的形态分化具独立性是发生“冲梢”的解剖学基础，“冲梢”时摘小叶能促进侧花序的抽生.芽内较高水平的iPA、ABA含量和b(iPA)／b(GA1/3)比值，以及叶片较高水平的总糖含量和b(C)／b(N)比值与花诱导有关，同时较高水平的b(iPA)/b(GA1/3)、ABA和b(C)/b(N)与花序原基形成有关.

In Shenzhen， flower bud physiological differentiationof‘SHIXIA’longan occurs between mid December and January of the next year，its morphogenesis differentiation beginning in late January. The whole‘shoot-like bud’come into inflorescence development period in early February，and its flowerets differentiates in late February， the developmental plasticity of the‘shoot-like bud’and the independence of flower bud morphogenesis between apical meristem and the axillary meristems are supposed to be the anatomical reasons for inflorescence‘flushing’. High levels of iPA and ABA， high b(iPA)/b(GA1/3) ratio of buds，high levels of total sugar content and high b(C)/b(N) in leaves were related to flower induction. High ABA level，high b(iPA)/b(GA1/3) and b(C)/b(N) were related to the formation of inflorescence.
