Abstract
A study was conducted on effect of different Zinc level on growth and physiological characteristics of tobacco seedlings in the floating system.The results showed that the growth level,the content of chlorophyll,the activity of NR and the root activity had higher values than CK when proper zinc was fertilized into the seedling pool. Among them, the optimum level was 100 mg·kg -1 and 200 mg·kg -1 . The results also showed at time of seeding desired to plant it had no good effects on the root absorbing area when Zinc level was over 300 mg·kg -1 . There weren't noticeable difference among treatment in the contents of Cl - and nicotine. CK had lower sugar contents and higher total N and K 2O contents than zinc fertilized treatment.
