The invention provides a method for improving
germination of rice seeds under salt stress and application, and relates to the field of
crop seed
germination, in particular to application of
melatonin and
vitamin C. The use concentration of the
melatonin is 10 micromol / L, 50 micromol / L, 100 micromol / L, 200 micromol / L and 300 micromol / L, and the use concentration of the
vitamin C is 5 micromol / L, 10 micromol / L, 20 micromol / L, 30 micromol / L and 50 micromol / L. The combined concentration of the
melatonin and the
vitamin C is 200 [mu] mol / L and 30 [mu] mol / L, the
germination rate and the germination potential are significantly improved after the melatonin and the
vitamin C are applied for treatment under salt stress, the germination effect of the rice seeds is optimal after the rice seeds are treated for 7 days by the 200 [mu] mol / L melatonin and the 30 [mu] mol / L
vitamin C, the inhibition effect of salt stress on the rice seeds can be significantly relieved, and the salt
stress resistance of the rice is improved. Therefore, the invention provides a theoretical basis for researching the mechanism that melatonin and
vitamin C improve rice seed germination under salt stress, and provides practical guidance for research on promotion of
plant salt tolerance at the same time.
