摘　　要：为准确掌握文冠果开花生物学规律,对宁夏银川植物园引种的文冠果(Xanthoceras sorbifolia Bunge)优良株系传粉生物学特性进行了研究。结果表明:文冠果为杂性花,即可孕花(两性花)与不孕花(雄花)同株,盛花期短,花粉活力较低,其繁育系统属于兼性异交、部分自交亲和、需要传粉者。In order to accurately grasp the flowering biology regularity of Xanthoceras sorbifolia Bunge, the pollination biology of introduced superior individual of Xanthoceras sorbifolia Bunge in Ningxia Yinchuan Botanical Garden were studied. The results showed that the superior individual had bisexual flower and infertility flower（male flower）, short full-blossom period,low pollen vitality,its breeding system belonging to simultane： ous xenogamy, partial selling affinity, need pollinators.
