枇杷花穗不同部位着果的观察研究

选择大五星枇杷的最后一批花作为观察材料,把花穗分为上、中、下3个不同部位,调查其花朵数和着果数,统计着果率;另外,在开花前用沙网对一些花穗进行套袋处理,防止昆虫授粉,但不防止风媒授粉,观察其着果情况。结果发现,花穗不同部位的着果率无显著差异;套袋花穗均没有着果。试验在一定程度上探索了枇杷开花结果的习性与规律,为枇杷的标准化生产提供依据。

Study on Fruit-setting Rate of Different Positions within Loquat Panicle

Flower number and fruit-setting rate within different positions of Dawuxing loquat(Eriobotrya japonica Lindl.) panicle both bagged with netting bags, for preventing flowers from insect pollination before blooming and unbagged were investigated, which was divided into three sections:basal,mesial and apical parts. The result showed that there was no significant difference in fruit-setting rate of different positions of the panicle but there were not any fruit could be seen on the panicle bagged with netting bags. The study revealed the flowering and fruiting habits of loquat,which would be reference to the normative production of loquat.
