Abstract:
The seeds of ‘Dongyu 99F1’ were used as the experimental materials,by using different concentrations of exogenous hydrogen sulfide,the germination percentage,the germination index,the activity of α-amylase ,the content of malondialdehyde and proline,the cell membrane relative permeability were investigated under salt stress,in order to provide reference basis for the salt resistance of Cucurbita pepo L.The results showed that under salt stress adding exogenous hydrogen sulfide obviously reduced the content of malondialdehyde and the cell membrane relative permeability,and significantly increased the germination percentage,the activity of α-amylase and the content of proline.The previous evidence showed that exogenous hydrogen sulfide was favorable to decrease the damage degree of cell membrane under salt stress,which enhanced the ability of rasisting salt stress in the seed germination of Cucurbita pepo L.,0.6 mmol·L-1 NaHS concentration was better.
