阿蒂莫耶番荔枝人工授粉

HAND POLLINATION IN ATEMOYA(Annona atemoya Hort. )

  • 摘要: 阿蒂莫耶番荔枝(Axnona atemaya Hort)的花有雌蕊先熟现象。花药在傍晚6至8时裂开,人工授粉能提高座果率。其方法是用毛笔直接从花药自然裂开的花上取花粉并立即授在花药没裂开的花上,如果花药在授粉当日保持不裂开,3周后座果率为94.0%。如果花药在授粉后的短期内裂开,座果率为23.8%,与对照座果率(18.9%)没有差别,说明柱头容受性在花药裂开前的短期内完全消失。
    Abstract: The flowers of atemoya are protogynous.Studies revealed that the anthers dehisced at 6-8pm.Hand-Pollination was very effective in increasing fruit act The way was to take the pollen direcyly from the flowers in anther dehiscence with a brush and then transfer it to other flowers without anther dehiscence.If the anther of the recipient remained in undehiscenceness on hand-pollination day the rate of fruit set world be 94.0% in threeweeks.However,if the anther dehisced a short time after hand pollination the rate of fruut set would be 23.9%,on the same level as the control,18.9%.This showed that stigma lost its receptivity completely shirtly before anther dehiscence.
