摘　　要：首次报道永顺落叶木莲开花与结实物候学特征。其花期在3月中旬至5月上旬,果期在4月中旬至10月上旬。其间有3次花周期和3次果实发育期,每次花周期和果实发育期天数不同。低海拔比高海拔开花早,落花期亦早,开花周期较短;低海拔较高海拔的果发育期长,种子散落期晚,果实最佳采集期在9月20日至9月30日。The phenology characteristics of blooming and fruiting of Manglietia deciduas Q. Y. Zheng was first reported in the paper. The florescence of Manglieia deciduas Q. Y. Zheng was in the middle of March to early of May, the fruiting period was in the middle of April to early of October. There were three times floreseenees and three times fruiting period. And the days of blooming and fruiting in every period was different. The blooming and shatter in low altitude was earlier than in high altitude, and the blooming period also shorter than it. The fruit development phase in low altitude was longer than in higher altitude, and the seed falloff period was latter. The best seed collection was 20th to 30th of September.
