| 摘 要： | 对42个秋子梨品种及野生类型的花粉特性和育性进行研究。结果表明,花粉粒形态多为椭圆形或长圆形;雄性不育现象明显,有23个品种表现出雄性不育,为花药败育类型,占调查群体的54.8%I;-KI染色法和培养基培养法测定花粉活力差异较大,培养基培养法测定更为准确;温室催花可以得到可育性花粉,育性偏低。

| Abstract: | Pollen characters and fertility of 42 kinds of cultivars and wild types of Pyrus ussuriensis was studied.The results showed that pollen grain was oval or oblong,and the male sterility phenomenon was obviously.23 cultivars showed male sterility,i.e.,anther was abortive,which accounting for 54.8%.There was a large difference between two pollen viability determination methods,I-KI and culture medium.Culture medium determination method was more accurate.Viable pollen could be got by putting flower cluster in the greenhouse,but the pollen fertility was low. |
