摘要
施用化学杀雄剂后，对小麦花粉生活力、花药脯氨酸含量进行了测定，并用扫描电镜观察了花粉表面结构变化。结果表明，“津奥啉”使小麦花粉淀粉聚集能力极度降低，花粉染色率仅２．７８％，花药重量降低６５．５％；花药脯氨酸含量只相当于对照的６１．２％；花粉表面及萌发孔等均发生畸形。
Wheat pollen vitality,proline acid content in anther have been determined and observed pollen surface construction variance through scanning electron microscope after application of CHA“JINAOLIN”in wheat.The results showed that amyl(starch)polymeric ability in wheat anther was significantly reduced;pollen dyeing rate was only 2.78%;anther weight was reduced 65.5%;anther proline acid content was 61.2% compared with ck;pollen surface and germinate aperture were aberration.CHA“JINAOLIN”induced pollen abortion in wheat.
