摘要
The effects of abscisic acid (ABA) on the growth of Malachium aquaticum under salt stress were investigated through a pot experiment. The results showed that ABA increased the biomass of M. aquaticum. With the increase of ABA concentrations, the root, stem, leaf and shoot biomasses of M. aquaticum increased when the dose of ABA was not more than 5 mu mol/L, and decreased when the dose of ABA was more than 5 mu mol/L. ABA also enhanced the photosynthetic pigment content and antioxidant enzyme activity of M. aquaticum. When applying ABA on M. aquaticum, the soluble sugar content in roots and leaves decreased, and the soluble sugar content in stems increased. Therefore, ABA could promote the growth of M. aquaticum under salt stress.
