Biological and Physiological Characters of Different Flue-Cured Tobacco Varieties in Seedling Period
The biological and physiological characters of different flue-cured tobacco varieties were studied in floating system.The results showed that there were significant differences in biological and physiological characters in seedling period.Except Yuyan 10,the nitrate reductase activity and root activity and dry-quality of Yuyan tobacco variety series were higher than those of Zhongyan 100,especially Yuyan 7 and Yuyan 9.So the seedling growth could reflect the properties of different tobacco cultivars.
