摘要
从北京市农林科学院农业综合发展研究所顺义科技示范园桃育种基地选取20个两用桃品种或品系作为研究对象,观察记录其花芽从萌动到落瓣期间的变化,确定了观赏期的划分标准。根据观赏期起始时间的早晚,拟定4月8日前开始有观赏价值的为早花品种或品系,4月9-10日的为中花品种或品系,4月11日以后的为晚花品种。结果表明：在所调查的品种或品系中,中花品种为多数,早、晚花品种较少。
Eighteen peach （Prunus persica L. ） varieties cultivated at the peach breeding base of science and technology demonstration in Shtunyi County, Dual-purpose peach varieties were selected to study and observe the blossom change from budding to withering in order to decide the criteria of blossom ornamental period. On the basis of blossom ornamental time, a variety that blossoms before April 8, between April 9-10 and after April 11, was named early, medium and late blossoming variety, respectively. The results indicated that among the varieties observed in the experiment, the medium blossoming varieties accounted for the most, but the early and the late blossoming varieties were fewer.
