摘要: 连续2年对蒙古扁桃自然居群的传粉昆虫进行了观察,用重力玻片法检测。结果表明:风媒导致的异株传粉作用可以忽略;蒙古扁桃花散布的气味、花蜜在诱导昆虫传粉中起主要作用;共发现访花昆虫17种,主要包括蜂类、蝇类、蝶类,以蜂类为主;昆虫访花频率与开花习性有关,访问者偏爱访问处于盛花期的花;蒙古扁桃趋向于虫媒的异花授粉,但缺乏忠实的传粉者。

Abstract: A two-year investigation on the blossom character and insect pollination of endangered plant Prunus mongolica Maxim showed that the role of wind-pollination could be neglected because the wind-diffused pollen of P. mongolica decreased rapidly with increasing distance. The nectar and the smell of P. mongolica blossom played a main role in inducing insect pollination. A total of seventeen kinds of insects including bees, flies and butterflies were observed as the pollinators, whose visiting frequency had a close relation to the characters of blooming. These insect pollinators preferred to visit the blossom in its flourishing anthesis. P. mongolica tended to be cross-pollinated by insects, but lacked of faithful pollinators.
