不同浓度盐胁迫对红砂渗透调节物质及抗氧化酶活性的影响
Effects of different concentrations of salt stress on osmoregulatory substances and antioxidant enzyme activities in red sand
[目的]为探究不同浓度盐胁迫下对荒漠灌木红砂(Reaumuria soongorica)渗透调节物质以及抗氧化酶活性的影响,丰富红砂耐盐机理研究,为干旱半干旱荒漠区生态修复工作提供参考依据。[方法]以当年生红砂幼苗作为试验材料,对其进行盆栽试验,该试验设置采用不同浓度梯度的NaCl溶液(0、0.1、0.2、0.3、0.4、0.5mol/L)浇灌红砂幼苗。分别于处理的 0、3、6、9d对幼苗进行采样,测定其脯氨酸、可溶性蛋白、Na+、K+含量以及 …查看全部>>
[Objective]To investigate the effects of different concentrations of salt stress on osmoregulatory substances and antioxidant enzyme activities of the desert shrub Reaumuria soongorica,and to enrich the study of salt tolerance mechanism of Reaumuria soongorica,in order to provide a reference basis for ecological restoration of arid and semi-arid desert areas.[Method]Red sand seedlings of the current year were used as test materials for potting experiment,whi…查看全部>>
