摘要
就异型雄蕊的概念、在被子植物中的分布、在传粉过程中的作用及其发育进行了概述,并对未来的研究方向作一展望。异型雄蕊指一朵花内的雄蕊在形态、大小、颜色等方面有显著的区别,并存在不同程度分工的现象。异型雄蕊在野牡丹科、茄科、千屈菜科、豆科、雨久花科等多个科中都有分布,但其分化与程度常随类群而异。虽然人们对于这一现象的认识由来已久,但研究尚不深入。对于异型雄蕊的研究可以加深人们对植物与其传粉者之间关系的理解,并为传粉生物学与植物繁育系统研究提供新的视角和启示。
The information in the literature concerning the concept ofheteranthery, the distribution ofheteranthery in angiosperm, the function of heteranthery in pollinating processes, as well as stamen development are reviewed, and the prospects in heteranthery studies are also discussed. Heteranthery, the phenomenon of stamens in a flower differing notably in shape, size, color and with labor discrimination, was first described more than one hundred years ago. Heteranthery exists in several angiosperm families, such as Melastomataceae, Solanaceae, Lythraceae, Leguminosae and Pontederiaceae, but the aspects and extent of differentiation often vary in taxa. Although people had realized this phenomenon for a long time, the studies are much less in-depth. Studies on heteranthery could strengthen people' s understanding about the relationship between plants and their pollinators, and provide new purviews and inspiration for pollination biology and plant breeding system research.
