摘要: 在内蒙古乌海市郊外定位观测了沙冬青的开花动态、花粉胚珠比(P/O)、花粉活力与寿命、柱头可授期、访花者的物种多样性、访花频率及自然条件下的结实率,结果表明:沙冬青单朵花的花期为5 d,P/O为(1 190±125),花粉寿命约4~5 d,柱头可授期3 d,访花者有30余种,以膜翅目、双翅目和鞘翅目昆虫为主,自然条件下的结实率因植株不同而差异较大,一般在30%~35%左右。

Abstract: The flowering dynamics, pollen-ovule ratio, pollen viability, pistil receptivity, species of floral visitors on Ammopiptanthus mongolicus, as well as visitors’ behavior and frequency were studied in the field of Wuhai city, Inner Mongolia. The main results were as follows: The flowers of A. mongolicus were 5 d in duration, their P/O was (1 190±125), pollen viability was 4~5 d, and pistil receptivity was 3 d. Their natural fruit set was 30%~35%. Insects among Hymenoptera, Diptera, Coleoptera and Lepidoptera, especially Anthophora spp., Hoplitis sp. and Chalicodoma sp. were the most common visitors.

Key words: Ammopiptanthus mongolicus, flowering characteristics, floral visitors, pollination
