“丽椪2号”无核椪柑花粉育性及超微结构观察

Observation on Pollen Fertility and Ultrastructure of Seedless Poonen Citrus Pollen

通过对“丽2号”无核柑品种的花粉发芽率、花粉生活力、花粉量测定和花粉粒扫描电镜超微结构观察等试验,以普通有核柑为对照,研究了其花粉育性。结果表明,“丽2号”花粉育性属于低育型,但花粉的低育性并不是导致其无核的关键因素,可能还因其胚囊败育所致。

Observation and experiment on germination ,percentage, viability, amount and ultrastructure of seedless Poonen Citrus pollen showed low fertility pattern compared with common Poonen Citrus and this was not proved to be the key factor leading to seedless.
