It was suggest that the yield of tobacco in unit area was significant increasing and the quality was improved along with the altitude increase in Liuyang tobacco area. The tobacco leaves production at the place where the altitude from 400 meter and 900 meter was propitious to postpone the bearing period and growth and development of tobacco plants. It was the base of maturation endurance and could advance the tobacco leave maturation degree of all parts of tobacco plant. And it could hasten the orange tobacco leave ratio of the whole tobacco plant. It was boosted leaves unwrapping of top tobacco plant and the statuses of tobacco leaves, especially the top leaves, were significantly improved. The tissue structure of all parts leaves on tobacco plant were more loosen and the colour and luster of tobacco leaves was more vivid. The nicotinamide content in top leaves were digressive at a certain extent, on the contrary, the contents of the reductive sugar and kalium were increased at different extent. At the same time, it was benefit to play down the pesticide rudimentai of tobacco leaves and increased security of tobacco leaves.

The results showed that in the growth period of R. glutinosa, soil ferulic acid, vanillic acid, and vanillin contents had a persistent increase, while β-hydroxybenzoic acid content increased first but decreased then. The addition of ferulic acid (8 μg·ml-1), vanillic acid (08 μg·ml-1), vanillin (12 μg·ml-1), and β-hydroxybenzoic acid (30 μg·ml-1) in water culture had stronger inhibitory effects on R. glutinosa root length, root mass, fresh plant mass, and plant height. Treating with test phenolic acids except β-hydroxybenzoic acid increased leaf chlorophyll content significantly, compared with the control. After treated with test phenolic acids, plant SOD and POD activities decreased after an initial increase, and plant malondialdehyde content increased. In the treatment of ferulic acid, root SOD and POD activities were the lowest, and roots were rotted and dead.
