黄果西番莲花形大 ,其结构和显花过程对昆虫 (特别是小型昆虫 )传粉有一定限制 ,自然授粉坐果率不高。人工授粉试验表明授粉受孕率与花粉贮藏时间、花粉潮湿、授粉量和花粉种、株间来源有关 :当天采集的花粉授粉受孕率为 97.5% ;室温下保藏 1d ,受孕率为 12 .8% ,保藏 2d受孕率为 0 ;柱头粘着花粉量大 ,受孕率为 92 .5% ,败育率 13.5% ,花粉量少 ,受孕率为 2 2 .5% ,败育率为 4 0 .7% ;种、株间授粉受孕率 10 0 % ,自花授粉、同株异花授粉、同株繁殖的无性苗 ,株间授粉均不孕 The yellow flower passionflower flower-shaped, its structure and process of blooming on insects (especially small insects) pollination has some restrictions, the natural pollination fruit setting rate is not high. Artificial pollination experiments showed that pollination conception rate was related to pollen storage time, pollen wetness, pollination amount and the sources of pollen species and strains. The pollen pollination conception rate of the same day was 97.5%, the pollination rate was 12.8% The rate of conception was 2 2.5%, the rate of abortion was 40.7%, the rate of conception was 92.5%, and the rate of abortion was 13.5%. Species, the rate of pollination between strains of 10%, self-pollination, the same cross-pollination, the same strain of asexual reproduction, inter-strain pollination are not pregnant
