| 摘 要： | 蜡梅花部形态和开花习性的观察结果：１花的构造上，雌雄蕊之间有支撑花柱群而特化的花托附属物；花被片基部有蜜腺；含挥发油的油细胞主要存在于花被片基本组织中。２．花芽分化过程分为形态分化前期、花被片分化期、雄蕊和花托附属物分化期、雌蕊分化期、药室分化期和胚珠分化期及其相应的解剖特征；花芽一般由新梢叶腋中的主芽分化形成；花芽主要开始分化的时间是顶梢自枯的五月中旬（扬州）；最早分化的是新梢存留叶位第一节。３．开花过程中，雄蕊存在着明显的离心外卧和向心聚合的运动；单花开放的过程为萌动期、蕾期、露瓣期、初开期、盛开期和落花期及其相应的物候标志。

| Abstract: | in this paper we have put such new points of view forward about the flower form and blooming characteristics of the wintersweet: 1. On the nower structure there is a special appendage supporting styles between stamen and gynoecium. There is a honey cup on the base of the envelope. Oil cell scontaining volatile oil is mainly in the basic tissue of the envelope. 2. In the flower-buds development, there are following Periods, form developing previous period, envelope developing period, stamen and appendage developing period, gynoecium developing period, pollen-chamber developing Period, ovule developing period and corresponding anatomic characteristics, flower-buds form from main-buds in the leaf-base of new branches. The time of flower buds developing is mainly in the mid-period of May (Yangzhou) while the top-branches wither, the first section of the remain leaf of the new branch develops must previously. 3. On the bloom process.there are cetrifugal outside movement and centripedal got-together movement, the bloom process contains sprout period, flower-bud Period, display-petal period, initiating bloom period, bloom period, wither period and corresponding biological marks. |
