Abstract

A pot experiment was carried out to investigate the effects of applying naphthalene acetic acid (NAA) on growth and physiology of Cosmos sulphureus. The results showed that application of NAA promoted the growth of C. sulphureus when the dose of NAA was not more than 15 mg/L. When the dose of NAA was lower than 15 mg/L, the biomass, the contents of chlorophyll a, chlorophyll b, total chlorophyll and carotenoid, the activities of SOD and POD, and the soluble sugar content of C. sulphureus increased, and got the maxima at the dose of 5 mg/L NAA. With the increase of concentration of NAA, the soluble protein and the CAT activity of C. sulphureus had the decreasing trend. Therefore, application of NAA could promote the growth of C. sulphureus at the dose of 5-15 mg/L.
