1951—1953年用108夫品种进行了授粉方法数量及脱落子房的胚珠的胚胎学等研究,所得结论如下:1、采用不同植株的混合花粉多量授粉时,在花柱内的花粉管发芽数较限量授粉和对照(自然授粉)的为多。2、采用限量授粉方法时,花粉管在胚珠的百分数较之混合花粉多量授粉和对照为少。3、混合花粉多量授粉照例对受精有良好的影响。而限量授粉则引起子房的大量脱落。4、花粉的数量和质量影响受精作用。在试验
From 1951 to 1953, the number of pollination methods and the embryo of the ovule ovary ovary were investigated by using 108 husbandry varieties. The conclusions are as follows: 1. When the mixed pollen of different plants pollinated in large quantity, the pollen tube germination number Limited pollination and control (natural pollination) for the more. 2, the limited pollination method, the percentage of pollen tube in the ovule pollen than the amount of pollination and the control is less. 3, a large number of mixed pollination pollination cases have a good effect on fertilization. The limited pollination caused a large number of ovaries off. 4, the quantity and quality of pollen affect fertilization. In test
