Embodiment 1
[0012] 1) The seeds of "Mingui" were irradiated with gamma rays, the radiation dose was 1.0 kGy, and the irradiation time was 10 minutes;
[0013] 2) Soak "Mingui" seeds in 30℃ water for 5 minutes;
[0014] 3) Soak the above-treated "Mingui" seeds with a calcium chloride solution with a concentration of 3 mM for 12 hours;
[0015] 4) The seeds of "Mingui" treated by the above steps were placed on gauze soaked in water, and germinated in the dark in a 28°C incubator, during which the gauze was supplemented with water to keep it moist. On the 15th day, the germination rate reached 94.6%, and the incidence rate was 0.15%.
