摘要
本文为枣开花生物学特性多年观察研究总结。枣单花开放过程可分为12期,有日开型和夜开型两类;花序开放,先零级花、再一级花、二级花、多级花顺序开放,不同级次开花曲线各有特点;枣吊上花序的花量与相应节位的叶面积有关;花器各部分生长不平衡是枣花开放的直接动力:天气影响枣花开放。
This artical is the conclusion of observation of flowering characteristics of jujube cultivars for many years. Flowering process of single flower was divided into 12 periods, and flowering time of the cultivars tested has two types, day-flowering type and uight-flowering type. Zeroclass-flower opens first in an infloescence, then first-class-flower and so on, successively, and flowering curve of each class flower has its own characteristics. Flower number in fruit shoot are related to leaf area. Weather influences the flower opening. For flowering mechanism of jujube, it was considered that one of the main causes of flowering was the different growth rates of jujubef lower portions.
