Abstract
The invention relates to a method for destroying wheat seed dormancy. The method comprises the following steps: (1) selecting a seed and enabling wheat to be in an environment with the humidity of 60-70%; (2) putting the wheat seed in warm water with the temperature of 35-40 DEG C, immersing for 24-36 h, and then putting in an environment with a temperature of 2-6 DEG C for 24 h; (3) utilizing chitosan with the concentration of 0.03-0.06% and nitric oxide (NO) with the concentration of 5-8 mmol/L to immerse the processed wheat seed; and (4) utilizing oxygen plasma to process the wheat seed. The method is capable of effectively destroying wheat seed dormancy, accelerating wheat seed germination, improving germination rate and providing powerful guarantee for breeding and large-scale plantation of wheat.
