Abstract:
Taking ‘Baiyesan’ fresh seeds of white cucumber as material，by using culture dishes sprout method，the water absorption rate，germination rate，relative conductivity and α-amylase activity of white cucumber treated by SNP，an exogenous nitric oxide donor，at the different concentration under 100 mmol/L NaCl stress were studied.The results showed that a certain concentration of SNP treatment could alleviate the damage of NaCl to the seeds，and increase the water absorption rate and germination rate significantly.At the same time，SNP treatment also could alleviate the inhibitory of membrane restoration and the decrease of α-amylase activity under salt stress，and the concentration of 0.10 mmol/L SNP was the best.
