摘要
利用聚丙烯酰胺凝胶电泳方法 ,研究 VA 菌根真菌接种后 ,紫茉莉苗端在不同发育阶段过氧化物酶及其同工酶的变化 .同工酶谱变化与发育阶段密切相关 :幼苗期有 2条带 P 、P ,成熟期 P 、P 带消失 ,相继出现新带 P 、P .接种 VA 菌根真菌后 ,各时期 POD酶活性都有所升高 ,并且 P
This paper studied the effect of VA mycorrhizal fungus( Selerocystis sinuosa ) to relationship between shoot apex development and peroxidase changes in Mirabilis jalapa with polyacrylamide gel electrophoresis. There are four bands of POD isozymes (PⅠ、PⅡ、PⅢ、PⅣ) in vegetative apices. PⅠ and PⅡ band disappeared in maturation period, new bands PⅢ 、PⅣ arising. The results showed, after plant was infected by VA mycorrhizal fungus POD activity increased in all vegetative period and the time in which PⅢ band appeared was post off.
