【摘要】 欧李果枝花芽数量随节位上升而增加,但雌蕊发育程度越来越低。上午8:00-10:00为开花高峰,中午12:00-14:00为撒粉高峰,无闭花撒粉现象。开花顺序由下至上;单花寿命为3-4 天;群体花期为7-9天;平均花药数为40,并呈正态分布。花芽萌动的生物学零度为0℃。
【Abstract】 The flower buds increase and quality of pistil decreases as branch nodes rise from its bottom to top. The peak of flowering time is in 8:00-10:00 before noon, and the peak of pollination time in 12:00-14:00 in a day. There is no cleistogamy. The flowering order is from bottom to top in the branch. Single flower exists for 3-4 days, and the flowering stage is in 7-9 days. The average sum of stamens is 40, and it looks like a nomal distribution. The temperature of flower bud sprouting is 0℃.
