通过对无核柑“赣 1号”品种的花粉发芽率、花粉畸形率、花粉量、花粉粒的大小、花粉生活力的测定及花粉形态观察等试验 ,与普通有核柑品种为对照 ,研究其花粉育性。研究表明 ,“赣 1号”花粉育性属中育型 ,其无核性状的成因并非由于花器发育不正常与雌雄配子不育所引起 ,可能因其胚早期败育或自交不亲和所致。 Through the experiments on the germination rate, pollen deformity rate, pollen amount, pollen grain size, pollen grain size, pollen viability and pollen morphology observed in the “Gan Wei 1” seedless seedless citrus, Control, to study its pollen fertility. Studies have shown that “Gan Wei 1” pollen fertility is a type of breeding, and its non-nucleus of the genesis is not due to abnormal development of flowers and male and female gamete infertility caused by its embryonic abortion or self-incompatibility Due.
