摘　　要：核桃(Juglans regia L.)为雌雄异花同株植物,其雌雄异熟性直接影响着开花、授粉等有性繁殖过程,从而影响核桃坚果的产量和品质。概述了国内外核桃雌雄异熟性的研究现状,对核桃雌雄异熟性在自然界中的表现、物候期特点、花芽分化进程、遗传特性和生产利用价值等进行了综述,以期反映核桃雌雄异熟性的规律及对高产栽培的指导意义。Walnut（Juglans regia L.） is monoecious plant.Dichogamy,affects sexual reproduction such as flowering and pollination,and ultimately influences the yield and quality of nut.The research situation of dichogamy in walnut was briefly introduced;and the manifestation of dichogamy in walnut,phenology characteristics,floral differentiation,genetic characteristics and utilization in cultivation was summarized so as to reflect the rule of dichogamy in walnut and provide guidance for walnut cultivation.
