番荔枝人工授粉效果的影响因素初探结果表明，第一朵花开放，给了一个贫穷的结果与手授粉比后来的。最早开放的花的花粉粒大部分处于四分体阶段，花粉壁厚，充满淀粉，不萌发。晚开放的花有更大比例的单个花粉粒，没有淀粉粒，和更大的细胞质流。许多谷物在几个小时后发芽了。
Preliminary research to investigate additional factors to increase results obtained by hand pollination in cherimoya (Annona cherimola Mill.) revealed that the first flowers to open gave a poorer fruit set with hand pollination than later ones. Flowers that opened earliest had the majority of the pollen grains in the tetrad stage with thick walls, full of starch and did not germinate. Flowers that opened later had a greater proportion of individual pollen grains, no starch grains, and greater cytoplasmic streaming. Many grains germinated after a few hours.
