摘要
通过对开花前后大量子房的切片观察发现,造成果荚脱落的原因是子房未受粉和正常受粉子房中多数种子的败育。其中造成种子败育的原因有:1.胚囊发育不正常;2.正常胶囊未受精;3.单受精;4.胚和胚乳的败育。
The fruit abscission of dwarf franch bean ( Phaseolus vulgaris var. humilis) may result from the unpollination or the high rate of seed abortion in the ovary.The causes of seed abortion are. 1) abnormal development of the ovule, 2) the normal ovule was not fertilized after anthersis, 3) single fertilization, 4) abortion of the embryo and endosperm in early stage of development.
