【摘要】 以玉米嫩单10为材料,分别用0,25,50,75 mmol/L的NaCl对其幼苗进行胁迫处理,并在胁迫处理后的2,4,6d测定幼苗叶及根中的脯氨酸含量,幼苗叶中还原糖含量、蛋白质含量,结果显示:在同一胁迫时间里,幼苗叶及根中脯氨酸含量随NaCl浓度的增加而上升;幼苗叶中还原糖含量随NaCl浓度的增加出现上升趋势,蛋白质含量随NaCl浓度的升高出现下降趋势。表明玉米嫩单10幼苗对NaCl胁迫具有一定的顺应反应。更多还原

【Abstract】 Ten-day old Maize seedlings were treated with 0mmol/LNaCl、25mmol/LNaCl、50mmol/LNaCl、 75mmol/LNaCl.The contents of praline in leaves and roots,the contents of reducing sugar and contents of protein in leaves were investigated in 2d、4d and 6d after treatment.Results showed: In the same day of stress,with the increased of NaCl concentration,the contents of praline will rise both in the leaves and roots,the contents of reducing sugar increased,while the contents of protein decreased in the leaves.These results were an acclimation of Mazie seedling under NaCl stress.更多还原
