Abstract:
Taking the strain ‘Zhongnong No.1’ of Pleurotus tuoliensis as the test material,the physiological indexes such as the protective enzymes activities,MDA content and soluble sugar content in four treatments (CK,T1,T2,T3) were determined.The physiological changes were studied,in order to provide reference basis and technical support for the cultivation and production of Pleurotus tuoliensis.The results showed that MDA content decreased at first and then increased.The activities of SOD,POD and CAT increased firstly and then decreased.The activities of SOD and POD were the highest in T1 treatment.There was no significant difference in CAT activity between T1 and T2 treatments,but both of them were significantly higher than that in CK (P<0.05).The content of soluble sugar increased at first and then decreased,and the content of soluble sugar in all treatments was significantly higher than that in CK (P<0.05).The content of free proline in all treatments was significantly different (P<0.05),and the content of free proline in T1 treatment was the highest.Comprehensive analysis showed that the physiological indexes were changed during the induction of low temperature,and the activities of protective enzymes,the contents of soluble protein and free proline were changed greatly.
