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.

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.
