摘　　要：作者以引进的8个桃品种为试材,对物候期、花器官和结果习性进行调查研究。结果表明,在阿拉尔垦区引进的桃品种3月中下旬萌芽、露瓣,4月初进入开花期,花期8~10 d。花冠直径存在极显著差异,‘春美’‘春蜜’花冠直径最大。蟠桃品种间花瓣大小差异不显著,普通桃品种间差异显著。‘中农金辉’花瓣横径、纵径和雄蕊数极显著小于其他品种;多数品种雌蕊数为2枚,‘锦绣’雌蕊数为3枚。花粉生活力、萌发率差异明显,‘中农金辉’花粉生活力最高,‘中蟠10号’花粉萌发率最高。引进的桃品种定植第2年结果,长中短结果枝均能结果,‘中农金辉’自然坐果率较高。In order to introduce 8 peach varieties as test materials,Investigation on the phenology,floral organs and the results of peach. The results showed that the in Alar area introduction of peach cuhivars mid late March bud ,petal baring, early April in flowering period ,flowering last 8-10 days, Corolla diameter was found highly significant differences, ＇Chunmei＇ ＇Chunmi＇ corolla diameter. Peach varieties petal size difference was not significant,ordinary peach cultivars exist significant differences,the transverse diameter,longitudinal diameter and stamens of ＇Zhongnongjinhui＇ were significantly smaller than those of other species. Most varieties of pistil number was 2,the number of the main 3 of ＇Zhongnongjinhui＇ ;Pollen viability and germination rate were significantly different,Highest pollen viability of ＇Zhongnongjinhui＇, ＇Zhongpan10＇ pollen germination rate was the highest. Introduction of peach cuhivar colonization can be a result of second years,long medium and short can results,the fruit setting rate is high of ＇Zhongnongjinhui＇.
