摘　　要：为探讨杏树花期性状特点,进而为育种、生产及设施栽培等提供花期生物学依据,对多个杏树品种的花期性状进行了详细的观察、调查研究。研究表明,39个杏树品种花冠直径平均为2.66cm,单花平均花瓣数为5.18个,花瓣数为典型5数的品种占35.9%,多于五枚的占64.1%,未有少于5数者。杏花雌蕊败育现象严重,不同品种雌蕊败育率高低差别极大。不同原产地品种在同一杏园花期较一致。自然条件下杏开花有昼开夜停的昼夜节律,是由气温昼夜变化引起的。10℃是大多数杏品种开花的"生物学最低温度"。To discuss the characters of apricot florescence phase, offer further biology basis for apricot breeding, production, and protected cultivation, particular observation and researches have been performed. Results indicated that the average corolla diameter of the 39 cultivars is 2.66cm, the average quantity of petals in single blossom is 5.18, the proportion of cuhivars with 5 petals in one blossom was 35.9%, the proportion of cultivars with more than 5 petals in one blossom was 64.1%,no cultivars with less than 5 petals in one blossom. The rate of female sterility of apricot blossom was very high, but it was distinct between different cultivars. The cultivars from different origins when planted in the same place have almost the same florescence. Under the natural conditions, the apricot had the rhythm that bloomed in the daytime and didn＇t bloom at night, this was arose by the change of air temperature from day to night. The lowest biological inflorescent temperature of most apricot-cuhivars was 10℃.
