绿豆幼苗对Cr3+胁迫响应的研究OA
Research on the Response of Green Bean Seedlings to the Stress of Cr3+
[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…查看全部>>
[Objective] The growth and physiological character of green bean seedling, which growth process was under the Cr3 + stress, was re searched. [Method] The response of bean seedling that was cultured in sands to the environmental stress of Cr3* was analyzed. [Result] The treatment of Cr with the content of <90 mg/L could increase the root vitality of bean seedling,and with the concentration-increasing of Cr3+, its root vigor decreased and its root aging spe…查看全部>>
