虫媒植物与传粉昆虫的协同进化(二)——虫媒花的性状对昆虫传粉的适应

Co-evolution of Entomophilous Plants and Pollination Insects(Ⅱ)——the Adaptation of Features of Entomophilous Flowers to Insect Pollination

植物依赖昆虫传授花粉,昆虫从植物获得花粉和花蜜作为食物,两者在漫长的进化过程中形成了密切的互惠共生关系。植物与传粉昆虫的相互作用被认为是被子植物花进化的重要推动力,植物发展了适应于异花传粉的花部结构,传粉者则框定了花的进化。植物的花部特征与传粉者行为、传粉机制和植物适合度间有丰内在的联系。

Entomophilous flowers depend on the pollination of insects, and at the same time, insects use pollen and honey as food. As a result, a co-evolution has been formed during their long evolutionary history. The plant-insect relationship is considered as an important impetus for the evolution of angiospermous flower. Angiosperm has developed the floral characters that are adaptable for cross pollination. Pollination insects limit the evolutionary mode of the entomophilous flower. An internal connection exists among floral characters, the behavioral responses and structual modifications of the pollinator insects, pollination mechanism, and the fitness of entomophilous plants.
