外源水杨酸对阿特拉津胁迫下甜菜幼苗生理特性的影响
Effects of Exogenous Salicylic Acid on Physiological Characteristics of Beet Seedlings under Atrazine Stress
摘要
Abstract
[Objective]In order to investigate the mitigating effect of exogenous salicylic acid on the toxicity of sugar beet seedlings under atrazine stress,[Methods]a pot experiment was conducted where beet seedlings were transplanted into the soil with an atrazine concentration of 0.06 mg/kg.After 3 days,different concentrations of salicylic acid were sprayed,and samples were taken to determine the growth and physiological and biochemical indexes of beet seedlings after 15 days.[Results]The results showed that compared with the control group,spraying 0.5 mmol/L salicylic acid had the most significant effect on alleviating the toxicity of beet seedlings.The plant height and root length increased by 90.0%and 70.4%,respectively;chlorophyll content increased by 36.2%;malondialdehyde and electrolyte permeability decreased by 18.7%and 49.0%,respectively;SOD,POD and CAT activities decreased by 59.1%,39.6%and 69.3%,respectively.[Conclusion]Salicylic acid can effectively alleviate the stress effect of atrazine on beet seedlings.关键词
