外源水杨酸对酸碱胁迫下杏鲍菇生理生化指标的影响OA

To explore the effect of exogenous salicylic acid on the acid-alkali tolerance of Pleurotus eryngii.In this experiment,Pleurotus er-yngii were used as materials,treated with different concentrations of salicylic acid under acid-alkali stress.The growth index,soluble protein and soluble sugars were measured to investigate the effects of exogenous salicylic acid on the physiological and biochemical indicators of Pleu-rotus eryngii.The results showed that Pleurotus eryngii grew best under acid stress,with higher soluble sugar content and soluble protein con-tent when the concentration of exogenous salicylic acid was 50 mg/L.And the Pleurotus eryngii grew best under alkali stress,with higher solu-ble sugar content and soluble protein content when the concentration of exogenous salicylic acid was 20 mg/L.Exogenous salicylic acid at an appropriate concentration can enhance the stress resistance of Pleurotus eryngii under acid and alkali stress to a certain extent.
