摘　　要：怀远石榴一般于４月中旬现蕾，５月上旬始花，花期持续到７月上旬，并有三个开花高峰期。石榴有两性花和雌蕊退化花，所占比例因品种、树龄和管理条件等因素而异，但雌蕊退化花所占比例较高。坐果率在品种间也有差异，并与两性花的比例有关。石榴的坐果习性是：短枝果在各类结果母枝中占有较高比例；侧花果和二花果在两年以上结果母枝中比例较高；一年生结果母枝的坐果具有特殊性，顶花果和三花果均具较高的比例。The research was complished at Huaiyuang,Anhui province.Bud emergence of POmegranate took place in the middle April and bud emergence to bloom required 18 to 20 days.
