摘要
作者在北京市桃花品种调查的基础上,以枝姿(包括枝条节间长短)作为第一级分类标准;以花型作为第二级分类标准;以花色、花瓣数、花萼数等作为第三级分类标准。并将花瓣5枚的定为单瓣;花瓣10—40枚的定为复瓣;40枚以上的定为重瓣。在此基础上,以种性为前提,将桃花分为真桃花系和山桃花系两大系,4大类,10个型,26个品种。
By means of three years investigation of peach-blossom cultivars found in Beijing, and based on the classification system of flower culti-vars presented by professor Chen Junyu, the author uses the branching habit as the first classification criterion, flower-form as the second criterion, and flower-color, number of petals and calyces as the third criterion. According to the specific characteristics,two series are divi-ded as prerequisites before cultivar classification, i.e., the Eupersica series and the Davidiana-hybrid series. Then, four groups and nine forms are subdivided for the 26 cultivars investigated. Such a new cla ssification system depicts both the evolutionary relationship among the peach-blossom cultivars,and is convenient for practical use at the same time. Therefore it can be considered as scientific and practical for classifying peach-blossom cultivars.
