影响黄果西番莲授粉受孕率的一些因子

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

Factor of Effecting Pollination of Yellow Passion Fruit

The size of flower is large ,but the structure and flower ing course lim its pollination by insect ,special the smaller, set fruits percent of natural po llination is lower. The trail of manual pollination shows that the pregnant perc ent is related to store time of pollen , moistened pollen, pollination capacity and origin of pollen.The pregnant percent of pollen is 97.5% then picking , the percent is 12.8% under temperature for one day, the percent is 0.0% after stored two day. The more amount of pollen,the higher percent is .
