| 摘 要： | 开花植物具有多样性的生殖系统，其中单性花的形成是促进异交、避免自交衰退、保持遗传多样性的重要途径。单性花物种分布于被子植物不同进化分支上的事实表明，物种的雌雄异花性可能是通过不同的机制进化形成的。本文从花发育、性染色体、植物激素和环境因素四个方面，阐述了被子植物性别分化调控机制的研究进展。

| Abstract: | Flowering plants exhibit spectacular sexual diversity. The formation of unisexual flowers is thought to promote outcrossing, prevent inbreeding depression, and enhance genetic variability. These unisexual species are distributed throughout the angiosperm phylogeny, indicating that dicliny has evolved independently numerous times, likely through diverse mechanisms. The current progresses of the sex differentiation in angiosperm, including floral development sex chromosomes, plant hormones, and environmental factors, were reviewed in this paper. |
