梯度碱胁迫对蚕豆幼苗生理生化指标影响的研究
A Study on Physiological and Biochemical Characteristics of Vicia faba L.Seedlings under Alkali Stress
摘要
Abstract
An analysis of free proline and malondialdehyde ( MDA) contents, resist oxidases activity in Viciafaba L. Leaves after4, 8, 12, 16 days treatment with NaHCO3(0, 50, 100, 150, 200, 250 mmol/L NaHCO3) was conducted. It was indicated that with extension of NaHCO3 stress time and increment of NaH-CO3 concentration, free proline and malondialdehyde (MDA) contents increased significantly. With extension of stress time,the activity of superoxide dismutase ( SOD) treated with 50 mmol/L NaHCO3 first increased and then declined significantly, and the activity treated with 100 -250 mmol/L NaHCO3 declined. The activity of catalase (CAT) treated by 50 mmol/L NaHCO3 increased, and the activity treated with 100 -250 mmol/L NaHCO3 first increased and then declined significantly. The activity of peroxidase ( POD) treated with 50 - 150 mmol/L NaHCO3 first increased and then declined significantly, and the activity treated with 200 -250 mmol/L NaHCO3 declined. In a word, Vicia faba L. Resists alkali stress in a certain degree.关键词
