Abstract
A pot experiment was carried out to investigate the effects of applying abscisic acid (ABA) on growth and physiology of Cosmos sulphureus. The results showed that application of ABA promoted the growth of C. sulphureus. ABA increased the biomass and photosynthetic pigment content of C. sulphureus. With the increase of ABA concentrations, the biomass and photosynthetic pigment content of C. sulphureus increased when the dose of ABA was not more than 5 mg/L, and decreased when the dose of ABA was higher than 5 mg/L. The application of ABA increased the soluble sugar contents in roots and shoots of C. sulphureus, and had the increasing trend with the increase of ABA concentrations. With the increase of ABA concentrations, the CAT activity and the soluble sugar content of C. sulphureus increased. All concentrations of ABA improved the POD activity, and only 5 and 10 mg/L ABA improved the SOD activity. Therefore, application of ABA could promote the growth of C. sulphureus.
