Abstract:
Taking alfalfa leaves on space flight as materials，the callus was induced.The half lethal concentration and lethal concentration of alfalfa callus under different concentrations of saline and alkali stress were studied，and 5 physiological and biochemical indexes under different saline-alkali stress were studied.The results showed that the half lethal and lethal concentration of alfalfa callus under NaCl stress were 1.2% and 1.8 mmol/L.The half lethal and lethal concentration of alfalfa callus under NaHCO3and Na2CO3stress were 0.4% and 1.0 mmol/L.The Alfalfa callus on space flight improved POD activity，soluble sugar and proline content，decreased the MDA content and relative conductivity，and the difference was significant.Space flight could improve saline alkali resistance of alfalfa callus，and alkali resistance was higher than that of salt resistance.
