| 摘 要： | 以雄性不育两用系DT2-3为试材,对其雄蕊发育过程进行了电镜扫描观察。结果表明:不育株和可育株的雄蕊从蕾期开始就表现不同,不育株雄蕊萎缩变小,进一步畸形,横切剖面无花粉粒;可育株雄蕊发育正常,剖面有发育成熟的花粉粒。该研究进一步揭示了雄性不育两用系DT2-3不育株败育的机制。

| Abstract: | The stamens development process of male sterile DT2-3 in watermelon was studied using scanning electron microscopic technique.The results showed that there were differences in the stamens between male sterile plants and male fertile ones from bud stage.The male sterile plants become atrophy and smaller and there was no pollen in transverse section of the stamens that become deformity.The male fertile plants developed normally,and there were mature pollen grains in transverse section of the stamens.It furthe... |
