Abstract:
Taking Pinellia ternate as the test material，100 mmol·L-1 NaCl solution was used to simulate alkali stress.Exogenous MeJA at concentrations of 10，50，100，200，400 μmol·L-1 was set to treat the seed stems of Pinellia ternate.At the same time，CK1 was determined with no NaCl stress and no addition of exogenous MeJA，and CK2 was determined with NaCl stress but no addition of exogenous MeJA.The effects of methyl jasmonate on the germination and seedling growth of Pinellia ternate under salt stress were studied，in order to provide a reference for clarifying the role of methyl jasmonate in alleviating salt damage to Pinellia ternate.The results showed that NaCl stress inhibited the germination potential，germination rate，germination index，vitality index，length of each organ，leaf area，fresh weight，plant height，water content of each organ and chlorophyll a，chlorophyll b，total chlorophyll,soluble sugar content of Pinellia ternate seeds，while increasing the contents of soluble protein and free amino acids.Exogenous MeJA could regulate effects of NaCl stress on the stem germination of Pinellia ternate，increase the leaf length，leaf width，leaf area，tuber length，tuber width，stem length，petiole length，plant height，fresh petiole weight，leaf moisture content，petiole moisture content，stem moisture content，individual plant moisture content，chlorophyll a，chlorophyll b，total chlorophyll，soluble protein，and soluble sugar of seedlings，and reduce the root-crown ratio.The adaptability of Pinellia ternate stems and seedlings to salt stress has been enhanced.The comprehensive analysis of the weighted TOPSIS and GRA fusion model shows that 400 μmol·L-1 MeJA has the best remission effect.
