- W260240837 abstract "[目的]研究绿豆幼苗在生长过程中受Cr3＋胁迫后的生长生理等情况。[方法]采用沙培法进行探究试验,分析Cr3＋胁迫环境下绿豆幼苗的响应。[结果]浓度〈90 mg/L的Cr3＋能增加绿豆幼苗根的活力,而随着Cr3＋浓度的增加,根的活力则下降,根老化加快,如当Cr3＋浓度为150 mg/L时,其活力为对照的56%。幼苗体内超氧化物歧化酶（SOD）、过氧化氢酶（CAT）等抗氧化酶对Cr3＋浓度反应也不同,当Cr3＋浓度在10~90 mg/L时,其活性呈现上升趋势并高于对照,之后则呈下降趋势并低于对照;当Cr3＋浓度为150 mg/L时,SOD、CAT活性分别为对照的51%和53%;脯氨酸和丙二醛（MDA）的含量随Cr3＋浓度增加而增加。[结论]低浓度（≤50 mg/L）的Cr3＋对绿豆幼苗生长影响不大,并能提高植株的抗逆性,而高浓度Cr3＋则抑制其生长。" @default.
