东北地区植物花色类别与传粉者之间的相关性

Correlation between Floral Color and Pollinators in Northeast China

花色一直被认为是吸引传粉者的诱物之一,是开花植物与传粉者长期相互选择的结果。作者统计了东北地区虫媒植物共计1 142种,同时利用出版物和网络资料提供的照片并比对标准色谱,确定这些虫媒植物花的颜色和色谱范围。发现在东北地区,单色系花中白色花所占比例最大,超过35%,黄色系和红色系次之,各占20%多一点,橙色花最少,仅占2%,其余为混合色系花,即一朵花或一个花序上的花有两种以上颜色。针对色谱分类结果以及东北地区常见的传粉昆虫的相关资料,讨论了花的颜色与传粉者之间的相关性。

Floral color has always been considered as an attraetant for pollinators, which is the outcome of co - evolution between flowering plants and pollinators. In this study, the floral colors chromatogram and of 1142 species of entomophilies plants in northeast China are summarized. It is found that white flowers count for over 35% in the monochromatic floral group, while yellow and red flowers count for slightly more than 20% for each. The orange flower is the least, only counting for about 2%. Others are secondary color flowers. Furthermore, the correlation between floral color and pollinators in northeast China is discussed.
