为阐明高海拔和低海拔产地生产的烟草种子是否存在活力及出苗差异，将低海拔产地（西双版纳）和高海拔产地（曲靖、昭通）生产的MS云烟85、MS云烟87、MS K326种子在光照培养箱中分别进行常温（26℃）、低温（13℃）萌发，2012—2013年分别在6个高海拔烟叶产区进行漂浮育苗，比较不同产地收获的种子室内发芽以及室外出苗和成苗速率。结果表明，不同海拔产地生产的烟草种子在常温下萌发，其发芽时间、发芽率没有明显差异，低温条件下，低海拔产地（西双版纳）生产的MS云烟85和MS云烟87种子的发芽率分别优于高海拔产地（曲靖、昭通）生产的种子；不同海拔产地生产的烟草种子在同一年份同一烟区的出苗时间差异不大，成苗时间相同。因此，种子产地的海拔高度不影响烟草种子的活力及出苗速率，种子活力的高低以及出苗的快慢与萌发及出苗时的温度有关。

In order to investigate the possible difference of seed vigor and seedling of tobacco seed produced in high altitude and low altitude, the seeds of MS Yunyan 85, MS Yunyan 87 and MS K326 produced in low altitude (Banna) and high altitude such as Qujing and Zhaotong were germinated under room temperature (26℃) and low temperature (13 ℃), respectively. Comparison of emergence time and seedling time also were conducted in 6 tobacco-plant regions. The results showed that germination rate and germination percentage of seeds were almost the same under room temperature. The seed germination percentage of MS Yunyan 85 and MS Yunyan 87 produced in low altitude were higher than that in high altitude. The seeding time of all seeds was almost the same, which were sown in the same tobacco-plant region in the same year. The seedling time was the same. So the seed vigor and seedling rate of tobacco seed cannot be influenced by the altitude of seed production.
