摘要: 为探究外源水杨酸对盐碱胁迫下燕麦抗氧化酶活性的影响,施加中性盐溶液和碱性盐溶液产生胁迫,并施加2种浓度外源水杨酸。结果表明:碱胁迫较盐胁迫显著抑制抗氧化酶活性;盐碱胁迫下抗性品种蒙燕一号抗氧化酶活性显著提高,丙二醛含量较品种太阳神少;施加外源水杨酸能显著提高抗氧化酶活性,对碱胁迫改善效果较好,0.05mmol/L浓度较0.10mmol/L浓度效果良好。

Abstract: To explore the effect of exogenous salicylic acid on the antioxidant enzyme activities of Avena sativa L.under saline-alkali stress,a neutral salt solution and an alkaline salt solution were applied to generate stress followed by the application two concentrations of exogenous salicylic acid.The results showed that alkali stress significantly inhibits antioxidant enzyme activity compared with salt stress,and the antioxidant enzyme activity of the resistant variety“Monyan No.1”was significantly improved under salt-alkali stress.The content of malondialdehyde was less than that of the taiyangshen,application of exogenous salicylic acid significantly increased antioxidant enzyme activity,which had a better effect on improving alkali stress,and the 0.05 mmol/L concentration was more effective than the 0.1 mmol/L concentration.

Key words: Avena sativa L.;Saline-alkali stress;Salicylic acid;Antioxidant enzyme activities
