普通小麦K型和T型雄性不育系花药同功酶研究

Study on Isozymes in Anther of Male Sterile Wheat Lines With Ae.kotschyi and T.timopheevi Cytoplasm

对不同发育时期花药过氧化物酶（ＰＯＤ）和酯酶（ＥＳＴ）同功酶的电泳分析表明，Ｋ型不育系ＰＯＤ同功酶与保持系基本一致，ＥＳＴ同功酶与保持系差异显著；而Ｔ型不育系ＰＯＤ和ＥＳＴ同功酶带数和活性单核期之后少于或低于保持系同功酶。

Peroxidase (POD) and Esterase (EST) isoenzymic PAGE analysis of different stages of anther development in common wheat( Triticum aestivum ) shows that POD isozymes in anther are approximately the same between K type male sterile line and its maintainer but EST isozymes have distinctive difference between them.The bands and activity of POD and EST isozymes of anther from T type male sterile line are fewer or lower than those from its maintainer after uninucleate stage.
