Abstract:

The germination rate and speed of Caragana korshinskii seeds with different storage years were tested to investigate the effects of storage years on seeds, find effective storage year of Caragana korshinskii seeds, and provide basis for the store and use of Caragana korshinskii germplasm resource. The results showed that the germination rate of Caragana korshinskii seeds with 1 storage year was the highest (about 99%), and the seeds were best for forestation. The germination rate of the seeds with 2 storage years was about 92.7% and the viability was passable. But the viability of the seeds with more than 3 storage years decreased very quickly, and the seeds with 4 storage years did not have germinating ability and could not be used for forestation.
