Effect of I-naphthylacetic acid on the growth of chrysanthemum plants

Abstract

Different concentrations of NAA (0, 50, 100, 200 and 400 ppm) were sprayed three times on Chrysanthemum morifolium cv. «White Canova». The results showed that there were significant effects on growth and flower quality when the level of NAA was between 50 and 200 ppm. Using 400 ppm NAA gave a slight effect on some recorded data.
