摘 要: | 通过发芽试验测定不同储藏时间的柠条种子发芽率、发芽进度,了解储藏时间对种子的影响,寻求柠条种子的有效贮藏年限,以期为柠条种质资源长期、安全贮藏和利用提供依据。研究结果表明:贮藏时间在3年以上的种子的生活力已经很弱,不再适合于播种造林。贮藏时间在4年以上的种子生活力基本消失,不能用于播种造林。随着储藏时间的增加,不仅发芽时间缩短,而且发芽率也降低,同时,发芽速度也大大减低。

Study on Germination of Caragana korshinskii Seeds with Different Storage Years |
| |
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. |
