中亚鸢尾的花粉生活力及其授粉

以野生中亚鸢尾(Iris bloudowii)为试材，在一天不同时间采集花粉测定其生活力；同一时间采集花粉，测定花粉的贮藏能力；在一天的不同时间对去雄套袋的花朵进行人工异花授粉，测定最佳授粉时间；用套袈的方法测定该物种自花授粉是否结实。初步得出结论：当花朵开放后，随着时间的延长，花粉生活力逐渐下降；花粉贮藏时间在24h之内，能保持较强的生活力；最佳授粉时间在上午12时左右；初步测定：中亚鸢尾是自花授粉不亲和性植物。

The Pollen Living Ability and Pollination of Iris bloudowii

Using the wild flower Iris bloudowii as testing material, the living abiliti es of pollens collected on different time of a day and the reserve abilities for pollens collected on the same time of a day were determined. The emasculate flo wers were covered by paper bag and were taken artificial pollination in differen t plants. With the method of cover bag, it was learned that whether the plant se lf-pollination got seeds. Initial conclusion was that when the pollen was reserv ed within 24 hours, its good living ability was still maintained; the pollen liv ing ability declined with time prolonging; the best time for pollination was 12: 00 in the morning. Iris bloudowii is the plant of self-incompatibility.
