汞离子胁迫对茭白及其体内黑粉菌的影响
Effect of Intimidation of Mercury Ion on Zizania latifolia Turcz. and Ustilago esculenta P. Henn. in its Body
【摘要】 研究了Hg2+对茭白(ZizanialatifoliaTurcz.)体内共生的茭白黑粉菌(UstilagoesculentaP.Henn.)的影响.对不同浓度Hg2+胁迫下茭白黑粉菌在幼茎中的分布状态进行了解剖观察,分析了在此过程中的MDA含量、可溶性蛋白含量、SOD活性和POD活性等一系列指标.试验结果表明,2mg/L以上的Hg2+胁迫能导致茭白黑粉菌的消亡,导致茭白茎尖不能膨大.
【Abstract】 The paper deals with the effect of Hg~ 2+ on Zizania latifolia Turcz. and Ustilago esculenta P. Henn. in its body. Under intimidation of different concentrations of Hg~ 2+ , the distribution state of Ustilago esculenta P.Henn in the tender stem of Zizania latifolia Turcz. is observed anatomically. During the process, a series of indexes as accumulation of MDA and soluble protein, SOD activities and POD activities are studied. The results indicated that Hg~ 2+ intimidation above 2mg/L can lead to disappearance of Ustilago esculenta P.Henn. and unexpandibility of stem tip of Zizania latifolia Turcz.
