| 摘 要： | 为探索长期储藏在种子库的及经过更新的烟草种子是否会发生遗传完整性和稳定性的变化,通过对不同品种植物学性状、农艺性状在20年前后变化的分析,发现不同品种在植物学性状上有一定的变异,主要表现在株型、叶形的变化,这种变化主要属遗传上的变异;在农艺学性状上也有较大变化,特别是株高和叶数变化较大,茎围增加,这种变化可能有遗传因素,但主要是由外界环境变化引起的.

| Abstract: | In order to investigate the changes of genetic integrity and stability of tobacco seeds after a long-term storage and update,several tobacco cultivars' botanical characteristics and agronomic traits were tested. The results showed that botanical characteristics,including plant style and leaf style, changed in some degree after 20-year storage and seed update, which might be attributed to genetic variation. Some agronomic traits had significant change, such as plant height, leaf number, stem width, which were mainly caused by the environmental condition. |
