Abstract:
Taking seed of Prunella vulgaris as test material,using 120 mmol?L-1 NaCl to imitate salt stress,the effects of sodium nitroprusside(SNP)at different concentrations(0.01-0.50 mmol?L-1)on seed germination and seedling growth under NaCl stress were investigated.The results showed that seed germination of Prunella vulgaris was significantly inhibited by NaCl stress,SNP treatments could relieve the inhibition of seed germination under NaCl stress in different degree.0.10 mmol?L-1 SNP increased the seed germination rate and germination energy by 68.06% and 130.56%,germination index and vigor index by 78.71% and 325.93%,radicle length and plumule length by 165.63% and 43.43%,radicleplumule ratio by 74.49%,and fresh weight by 57.66%.The comprehensive evaluation indicated that the concentration of SNP at 0.10 mmol?L-1 was the best relieving effect in all the treatments.
