Embodiment 1
[0022] A kind of method utilizing hormone and cold stratification to break the dormancy of Rowan seed, specifically comprising the following steps:
[0023] (1) Soak the Rowan seeds harvested in the same year in warm water at 40°C for 48 hours, and change the water once after soaking for 24 hours;
[0024] (2) putting the seeds obtained in step (1) into a potassium permanganate solution with a mass fraction of 0.5% for disinfection for 2 hours, and then repeatedly washing the seeds with clear water until colorless;
[0025] (3) Put the seeds gained in step (2) into 100mg / L gibberellin solution and soak for 6h, then take out the seeds and put them into a nylon mesh bag with a mesh size of 40 mesh;
[0026] (4) Lay the nylon mesh bag containing the seeds and the sterilized wet river sand in layers, the mass ratio of the seeds in the nylon mesh bag to the wet river sand is 1:3, stratify at 3°C for 60 days, Stir once every 7d, and the overall humidity of seeds and wet river san...
