摘要
从单穗、单株和植株群体3个方面调查分析乐山古荔枝雌雄花开花特性。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。雄花在开花后10～18d，21～25d分别出现两个落花高峰。
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. The results showed that the flowering order was from male flower to female flower to male flower. The flowering period of male flower synchronous with female flower in the population were longer than that in a single ear or a single plant. The peak time of female flower dropping was 7- 10 d after flowering. And two peaks of male flower dropping were 10-18 d and 21-25 d after flowering, respectively.
