| 摘 要： | 通过对90个烟草材料的种子进行发芽率和发芽势的测定,结果表明:同一年代不同品种种子的发芽率和发芽势存在一定差异,且发芽率相近的品种发芽势也相近;不同年代同一品种种子的发芽率和发芽势差异也比较明显,它们随着贮藏年代的延长而降低。

| Abstract: | This paper reports the effects of preservation times on the germination percent and germination through tests to ninety-three tobacco material seed.The results show that the germination percent and germination energy of seeds which have been harvested in the same and belong to different barieties have some differentiae and germination energy is close when their germination percent is close.In addition,the germination percent and germination energy of seeds which have been harvested in the various years and belong to the same variety had also relatively obvious differentiae and they reduce as the extension of preservation times. |
