摘　　要：以1a生桔梗为试材,对桔梗雌蕊柱头与雄蕊花药成熟时间以及桔梗开花散粉时间进行研究,以期为桔梗有性杂交提供科学依据。结果表明:桔梗有性杂交时母本去雄的最适宜时期为花蕾长2.0cm,花冠初裂、紫色。父本授粉时选择花长3～5cm,宽2.0～3.5cm,花冠蓝紫色且花冠露出花萼,但未完全露出时最佳。Annual Platycodon grandiflorum was used as test materials,the stage of maturity of pistil stigma,stamen anther and the time pollen shedding from anther locules of Platycodon grandiflorum were studied,in order to provide scientific basis for sexual hybridization platycodon.The results showed that it turned out that when platycodons were making sexual hybridization,the most suitable period for female parent castration with bud long was 2.0 cm,corolla initial crack and violet,while male parent pollinating,with bud 3 to 5 cm long,2 to 3.5 cm wide,bluish violet corolla,corolla exposing calyx,but not fully exposing.
