十三、雌蕊、雄蕊掌类植物的花是两性花,即一朵花中同时存在着充分发育的雌蕊和雄蕊。雌蕊和雄蕊是生殖器官——花的重要组成部分,但掌类植物花中的雌蕊和雄蕊也有一定的欣赏价值。雌蕊生于花的中央,雄蕊群生在雌蕊的周围。雌蕊一般较雄蕊长,雌蕊由柱头、花柱、子房三部分组成。柱头多数分裂,有些种类柱头的裂片很大而色美。有的花柱也很美。如南国玉属部分种类的柱头呈紫色,鹿角柱属种类的柱头为绿色,白花蟹爪的柱头和花柱呈鲜艳的浅玫红色,都与花瓣色彩构成强烈对比,非常悦目。龙爪球属的黑冠球花柱又长又粗,色彩鲜红,非常别致。雄蕊由花药和花丝组成。一朵花的全部雄蕊总称“雄蕊群”。花丝顶端具有两室的花药,内贮黄色花粉。花丝、花药和花粉的颜色也是花的色彩的一部分。雌蕊和雄蕊有同时成熟的,也有先后成熟的。
Thirteen, pistil, stamen Palm plant flower is a bisexual flower, that is, a flower at the same time there are fully developed pistil and stamen. Pistils and stamens are important parts of reproductive organs - flowers, but pistils and stamens in the palms of flowers also have some appreciable value. Pistils are born in the center of the flower, the stamen group in the periphery of the pistil. Pistils generally longer than the stamens, pistils from stigma, style, ovary three parts. Stigma mostly divided, some species stigma lobes large and color the United States. Some styles are also beautiful. For example, some species of southern China are stigma purple, the stigma of the genus Antler is green, and the stigma and style of the white-crab claw are brightly rosy red, all in striking contrast with the petal color. Dragon claw genus is a long, thick black crown, bright red, very unique. Stamens consist of anthers and filaments. The total stamen of a flower “” stamen group ". The top of the filaments has two-compartment anthers, storing yellow pollen inside. The color of filaments, anthers and pollen is also part of the color of the flower. Pistils and stamens have both mature, but also has matured.
