The investigation and analysis of the flowering characteristics of male and female flowers of Leshan old age litchi were conducted from single ear, single plant and plant population.
结果表明:乐山古荔枝雌雄花交替开放的顺序是雄-雌-雄;植株群体雌雄花开放时间比单穗和单株长;雌花在开花后7~10d为落花高峰期。

用石蜡切片法对水曲柳雌花发育、大孢子发生及胚胎发育的过程进行了解剖学观察。
Anther abortion during litchi female flower development were studied by applying scanning electric microscope,transmission electron microscope and DAPI fluorochrome methods.
应用扫描电镜、透射电镜和DAPI荧光染色方法对荔枝雌花发育过程中花药败育进行了研究,结果发现:败育的花药在减数分裂之前其药壁细胞即开始解体,减数分裂后,药壁组织发生细胞程序性死亡,导致对营养物质竞争力的减弱;发生凋亡的细胞,细胞核染色质固缩,其电子密度高于正常,核仁消失,染色质趋边化的双层核膜降解,有的核变形而凹陷,核膜破裂,在核膜破裂处可见到由核物质组成的凋亡小体。
