摘　　要：从番荔枝的开花进程与花期、雌雄异熟性特点、雌雄配子发育与授粉特性、雌雄异熟性的激素调控和雌雄异熟性的遗传分析5个方面综述了番荔枝开花进程和雌雄异熟性领域取得的研究进展,并对其今后的研究方向进行了展望。Annona squamosa Linn.is a typical dichogamy plant and also a protogynous plant.The pistils mature first in a tree.When the stamens are matured,the pistils cannot be pollinated.Unmatched female and male flowering periods result in a low pollination rate and fruit setting rate of Annona squamosa.Thereby it reduces the yield and quality and restricts the development of Annona squamosa industry.Based on the results of previous studies,this article has summarized the research progress about dichogamy and flowering process of Annona squamosa from the fields of floral bud differentiation and flowering period,dichogamy,development of male and female gametes and pollination features,and hormone regulation and genetic analysis of dichogamy of Annona squamosa.The future research direction is discussed as well.
