Abstract:
Cassia obtusifolia L.seed was used as the material，treated by different concentration of NaCl，then the germination indexs，radical length，hypocotyl length，biomass，soluble protein content，soluble sugar content，malondialdehyde content and relative electric conductivity was measured to research effect of salt treatment on germination of Cassia obtusifolia L.seed.The results showed that，low concentration(25 mmol/L)of salt treatment promoted seed germination and soluble sugar content；middle concentration (50 mmol/L)of salt treatment had no significant effect on germination indexs，but restrained hypocotyl length and biomass and promoted soluble protein content，soluble sugar content and relative electric conductivity；high concentration of salt treatment (100 and 200 mmol/L）restrained the seed germination significantly，promoted accumulation of soluble protein content，soluble sugar content，malondialdehyde content and relative electric conductivity.So，low concentration of salt was benefit for germination of Cassia obtusifolia L.seed，but high concentration of salt was harmful.
