氯化钠对小麦幼苗乙醇酸氧化酶活性和叶绿素含量的影响

EFFECTS OF SODIUM CHLORIDE ON THE ACTIVITY OF GLYCOLATE OXIDASE AND THE CONTENT OF CHLOROPHYLL IN WHEAT SEEDLINGS

摘要: 本文报告氯化钠对小麦幼苗乙醇酸氧化酶的促进作用。试验结果表明,用氯化钠喷施小麦幼苗20小时后,乙醇酸氧化酶活性升高21％,体内蛋白质含量升高24.2％。用0.1、0.2、0.5mol/L的氯化钠培养幼苗,乙醇酸氧化酶活性分别比对照增加23％、61.1％和28.6％;蛋白质含量分别比对照增加12.8％、29.4％和18.1％;叶绿素含量分别下降2.8％、2.8％和22.2％。本文讨论了氯化钠影响乙醇酸氧化酶活性的机理。

Abstract: In this paper we report the effects of sodium chloride on the activity of glycolate oxidase in wheat seedlings. At 20 hrs after spraying sodium chloride on wheat seedlings, the activity of glycolate oxidase increased by 21% and the content of Protein increased by 24.2%.After the seedlings had been cultivated with 0.1, 0.2, 0.5 mol/L of sodium chloride, the glycolate oxidase activity increased by 23.0, 61.1, and 28.6 percent respectively over the control| the contents of proteinincreased by 12.8, 29.4, and 18.1 percent respectively over the control, but the chlorophyll content decreased by 2.8, 2.8, and 22.2 percent respectively. The mechanism of increase of glycolate oxidase was discussed.
