摘要： 以16个桃花品种试材,研究了桃花的育性和结果习性。试验表明:桃花大部分品种花粉生活力正常,能满足自花授粉的需要。白花山碧桃雌蕊完全退化;人面桃、洒红桃、绯桃为多柱头现象;红叶桃雌蕊呈正常、短缩败育和多柱头等多种类型;其余品种雌蕊发育基本正常。垂枝桃、鲜食观赏桃和寿星桃类均有较高自然坐果率,菊花桃人工授粉坐果率普遍偏低。并据以上试验结果,初步分析了桃花品种坐果率偏低的原因。

Abstract: Sixteen cultivars of peach-blossom were used to study on the fertility and fruit habit.The result showed that the pollen in the most of cultivars of peach-blossom had normal vitality and can meet the need of self-pollination.The pistil of ″Bai Hua Shan Bi Tao″ was completely degenerative,and there were polystigmas in the ″Ren Mian Tao″,″Sa Hong Tao″and ″Fei Tao″.In ″Hong Ye Tao″ peach the pistil were normal,or short and infertile,or polystigma and so on.The pistil of cultivars of peach-blossom were mainly normal.Pendulous-stem peach group,fresh and ornamental peach cultivars and dense-compact peach group had very high natural fruit set percentage.The fruit set percentage of ″Ju Hua Tao″ was universally low under the controlled pollination.And according to these results,there was a litter initial tentative conclusion on the reasons of the low fruit set percentage.
