| Abstract: | In order to improve the morphological characters, Paclobutrazol(PP333) was applied at different concentration to Narcissus tuber before indoor water-culture. The results showed that the treatment by PP333 at 200-400 mg/L can effectively inhibit the vegetative growth of Narcissus. It was observed that the treatments reduced plant height, increased chlorophyll content, extended blooming period of individual flower. Therefore, the ornamental value of indoor water-cultured Narcissus can be significant improved by PP333 at suitable concentration. |
