[0040] A method for identifying salt tolerance of different wheat varieties during germination, the steps are as follows:
[0041] (1) Determination of relative germination rate and relative germination potential of wheat to be tested
[0042]Add 4.68g, 9.36g, and 14.04g NaCl to each liter of distilled water to prepare 80mmol / L, 160mmol / L, and 240mmol / L NaCl solutions, and use 0mmol / L, 80mmol / L, 160mmol / L, and 240mmol / L NaCl solutions respectively Treat the wheat seeds to be tested, place them in a light incubator at a constant temperature of 21°C, and cultivate them in the dark for 24 hours, then place them at room temperature, measure the germination rates of the control group and the treatment group three days later, measure the germination potential after seven days, and calculate The relative germination rate and relative germination potential of the wheat varieties to be tested under the treatment of 0mmol / L, 80mmol / L, 160mmol / L, and 240mmol / L NaCl solution:
