Abstract

The invention discloses a method for breaking the dormancy of the seeds of Chrysanthemum chinensis and improving the germination rate. The method includes: (1) soaking the seeds with 5-10 μmol / L Karrikinolide aqueous solution for 24 hours; (2) mixing the soaked seeds with perlite at a low temperature of 4°C for 30-40 days; (3) soaking the seeds with 5-15 μmol / L The stratified seeds were soaked in an aqueous solution of sodium nitroprusside and 2.5-10 mmol / L hydrogen peroxide for 24 hours; (4) sown in a sand bed. The method of "seed soaking + stratification + seed soaking" is adopted in the method to break the dormancy of the seeds of S. japonica and improve the germination rate, so that the germination rate reaches more than 80%, and the stratification in the traditional method of breaking the dormancy of S. japonicus seeds is greatly shortened. In time, the technical bottleneck of large-scale production of golden cherry seedlings using seeds has been solved.
