摘  要:对枣花芽形态分化和花器构造进行了观察。结果表明:枣花芽是随枣吊的生长而分化的,分化速度快,单花芽分化期仅需6天,花序分化需20天。单花分化过程分为分化初期、花序分化期、萼片分化期、花瓣分化期、雄蕊分化期和雌蕊分化期。枣花小,具萼片、花瓣、雄蕊各5枚,雌蕊柱头两半裂,蜜盘肥大,是典型的虫媒花。Flower--bud morph differentiation and flower structure of jujube have been observed. The results show that the flower--bud were differentiated with growth that shedding shoot of jujube, the differentiation speed is quick, the single bud differentiates phase only need 6 days, inflorescence differentiation takes 20 days. Single flower differentiation course divide into the initial differentiation stage, inflorescence differentiation stage, sepal differentiation stage, petal differentiation stage, stamen differentiation stage and pistil differentiation one. The jujube flower is small, have sepal, petal, 5 respectively stamens, column cap two halves of the pistil split, the honey set is loose, is a typical entomophilies flower.
