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:柠条种子在采种后第1年播种最好,发芽率在99%左右,种子活力最强;第2年发芽率在92.7%,种子活力尚可;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。随着柠条种子储藏时间的增加,其发芽率和发芽速度均降低。
通過髮芽試驗測定不同儲藏時間的檸條種子髮芽率、髮芽進度,瞭解儲藏時間對種子的影響,尋求檸條種子的有效貯藏年限,以期為檸條種質資源長期、安全貯藏和利用提供依據。研究結果錶明:檸條種子在採種後第1年播種最好,髮芽率在99%左右,種子活力最彊;第2年髮芽率在92.7%,種子活力尚可;貯藏時間在3年以上的種子的生活力已經很弱,不再適閤于播種造林;貯藏時間在4年以上的種子生活力基本消失,不能用于播種造林。隨著檸條種子儲藏時間的增加,其髮芽率和髮芽速度均降低。

The germination rate and the germination speed of Caragana korshinskii seeds with different storage years were determined to investigate the effects of storage years on seeds, find effective storage duration of Caragana korshinskii seeds, and provide basis for the store and use of Caragana korshinskii germplasm resource. It was found that the highest germination rate (about 99% ) of Caragana korshinskii seeds was recorded in the stoage period of one year, and the seeds were the best for forestation. The germination rate of the seeds stored for 2 years was about 92.7% and the viability was passable. But the viability of the seeds stored for more than 3 storage years decreased very quickly, and the seeds stored for 4 years did not have germinating ability and could not be used for forestation. With the storage years of Caragana korshinskii seeds increased, whose germination rate and germination speed all reduced.
