摘　　要：在春、夏、秋不同生长季节分别采用桂花新梢进行扦插试验,并对当年采集的桂子种子实施层积处理,探讨了桂花的繁殖特性。结果表明,桂花扦插后35 d可形成愈伤组织,但愈伤组织并不生根,而是皮部生根,新根位于插穗下一节皮部附近。插穗保留半木质化顶梢的顶芽,可使50%以上的顶芽发芽、抽枝,能提高扦插苗的商品价值。桂花种子在常温层积中需165～180 d完成后熟,可以通过控制层积用沙的湿度来影响桂花种子的发芽时间。The cutting woods of Osmanthus fragrans could engender callus at 35 d after cuttage.However,the root occurred from the cortex instead of callus.The rootage was in the cortex near the undermost joint.When the cutting slips were with semi-lignified apical bud,more than half of the apical buds could germinate and burgeon,which could improve the commercial value of the cottage seedling.Postripeness of O.fragrans seeds need 165～180 d under room temperature to achieve after ripening;and the germination of O.fragrans seeds would be affected by controlling the sand moisture of stratification.
