Abstract: [Objective] To study the cross pollination compatibility of different varieties in plum(Prunus domestica L.)and lay the foundation for the configuration and cross breeding of the European cross pollination varieties.[Method]Determination of Victoria of pollen number,pollen viability,fruit-setting rate and growth status of pollen tube of three Prunus domestica L.cv.Stanley,Prunus domestica L.cv.French and Prunus domestica L.cv.[Result]The pollen amount of single flower was Prunus domestica L.cv.Stanley 5.00 ten thousand grain/flower,Prunus domestica L.cv.French 3.12 ten thousand grain/flower and Prunus domestica L.cv.Victoria 1.45 ten thousand Grain/flower.Pollen viability was more than 20;,belonged to the medium-higher pollen viability;3 various of plum cultivars self-fertilization of fruit-setting rate,Prunus domestica L.cv.Victoria 0.47;,Prunus domestica L.cv.French 5.71;,Prunus domestica L.cv.Stanley 8.14;;3 plum cultivars pollination: the Prunus domestica L.cv.Victoria as the female parent,respectively in the Prunus domestica L.cv.French and Prunus domestica L.cv.Stanley as male parent,the fruit setting rate was respectively 5.88;,7.17;.Prunus domestica L.cv.Stanley,Prunus domestica L.cv.Victoria as female parent and male parent as the fruit setting rate was 12.15;,with Prunus domestica L.cv.French was a combination of male fruit rate was 6.34;.Prunus domestica L.cv.French as the female parent,Prunus domestica L.cv.Stanley and Prunus domestica L.cv.Victoria as male parent pollination,fruit setting rate were 11.49;,14.41;.When the plum and Prunus salicina L.cv.with Meilili as male parent after pollination,the fruit-setting rate was ≤ 0.05;,showing incompatibility of hybridization;the fluorescent display plum varieties mutual pollination showed affinity,self-fertilization was slow or abnormal pollen tube emerged,only a small amount of pollen tube went into the base of the style;the phenomenon of pollen tube bending or apex expansion after the hybridization of Prunus salicina L.cv.with Meilili hybrid appeared.[Conclusion]Prunus domestica L.cv.Stanley,Prunus domestica L.cv.French,Prunus domestica L.cv.Victoria and Prunus salicina L.cv.Meilili belonged to the middle-higher pollen vitality of varieties;plum cultivars self-fertilization of fruit-setting rate was relatively lower,so they need pollination tree;the pollen viability and stigma fluorescence microscopy,Prunus domestica L.cv.French and Prunus domestica L.cv.Stanley as pollination varieties to Prunus domestica L.cv Victoria,Prunus domestica L.cv Victoria as for Prunus domestica L.cv.French pollination varieties,Prunus domestica L.cv.Stanley appropriate pollination varieties Prunus domestica L.cv.Victoria and Prunus domestica L.cv.French;Prunus domestica L.cv.French×Prunus domestica L.cv.Victoria was better pollinators;Prunus salicina L.cv.Meilili was not fitted with the plum pollination.

摘要： [目的]研究欧洲李不同品种间授粉亲和性,为欧洲李授粉品种的配置和杂交育种奠定基础.[方法]测定3个欧洲李品种斯坦勒、法兰西、女神的花粉量、花粉活力、品种间授粉坐果率,结合荧光显微观察授粉亲和性.[结果]3个欧洲李品种的单花花粉量分别为斯坦勒5.00×104粒/花,法兰西3.12×104粒/花,女神1.45×104粒/花,花粉萌发率≥20;,自交坐果率分别为女神0.47;、法兰西5.71;、斯坦勒8.14;.3个欧洲李品种间授粉的坐果率为:以女神为母本,分别以法兰西、斯坦勒为父本,坐果率分别是5.88;、7.17;.以 斯坦勒为母本,女神作为父本的坐果率为12.15;,以法兰西为父本的组合坐果率为6.34;.以 法兰西为母本,斯坦勒和女神为父本的授粉组合中,坐果率分别为11.49;、14.41;.美丽李为父本为欧洲李授粉后坐果率都≤0.05;,为杂交不亲和.柱头荧光观察显示欧洲李不同品种间相互授粉杂交表现亲和,自交则出现受精缓慢或花粉管畸形等现象,只有少量的花粉管进入花柱基部;欧洲李和美丽李杂交后出现花粉管弯曲或先端膨大现象.[结论]3个欧洲李品种花粉量大,活力强,自交坐果率都比较低,表现为自交不亲和.异花授粉杂交亲和.法兰西和斯坦勒适合作女神的授粉品种,女神适合作法兰西的授粉品种,女神和法兰西适合作斯坦勒的授粉品种;美丽李不适合作欧洲李的授粉品种.
