摘要
为探究干旱胁迫对冬黑麦生长及生理指标的影响,使用 15%聚乙二醇-6000(PEG-6000)对水培俄罗斯冬黑麦 BK01 模拟干旱胁迫,分别在处理 0(CK)、3、6、9、12、24 h测定不同胁迫时叶片各项生理指标.结果表明,随胁迫时间的延长,冬黑麦叶片脯氨酸和丙二醛含量呈上升趋势;过氧化氢酶、过氧化物酶、超氧化物歧化酶活性、可溶性蛋白和可溶性糖含量呈先上升后下降趋势;相对含水率呈下降趋势;研究结果将为冬黑麦抗旱研究进展提供新的理论依据.
Abstract
In order to investigate the effects of drought stress on the growth and physiological indexes of winter rye(Secale cereale L.),the hydroponic Russian winter rye BK01 was simulated by using 15%PEG 6000(PEG-6000).The physiological indexes of leaves under different stress conditions were determined at 0(CK),3,6,9,12 and 24 h,respectively.The results showed that the contents of proline and malondialdehyde in winter rye leaves increased with the prolonging of stress time.The activities of catalase,peroxidase,superoxide dismutase,soluble protein and soluble sugar increased first and then decreased.The relative water content showed a decreasing trend.This study will provide a new theoretical basis for the research progress of drought resistance of winter rye.
