Fig. 1. Chemical structure of brassinosteroid biosynthesis inhibitor (Yucaizol) and gibberellin biosynthesis inhibitor (Trinexapac-ethyl).

Fig. 2. Effect of Yucaizol on retardation plant height in rice seedlings. The plants were treated with Yucaizol at the specified concentrations. From left, control (the first three plants); 0.5 μmol/L (the second three plants) 1.0 μmol/L (the third three plants) and 10.0 μmol/L (three plants from right). Plants were grown under the conditions described in the experimental section for 10 d. Bar = 2 cm. All the experiments were done at least three times to establish the repeatability.

Fig. 3. Effect of Yucaizol on lamina joint bending angle in rice seedlings.The plants were treated with Yucaizol at the specified concentration (0-10 μmol/L) and grown under the conditions described in the experimental section for 10 d. The average bending angle of the lamina joint was measured (n = 8). Error bars represent SD. All the experiments were done at least three times to establish the repeatability.

Fig. 4. Effects of Yucaizol and Trinexapac-ethyl (TPE) on growth of rice seedlings. The plants were treated with Yucaizol from left: 0, 0.5, 0.5 and 0 μmol/L mixed with TPE at a concentration of (from left): 0, 0, 0.5 and 0.5 μmol/L. Rice plants were grown under the conditions described in the experimental section for 10 d. The upper picture displays the chemical induced phenocopy of rice. The plant height was measured (n = 8). Error bars represent SD. All the experiments were done at least three times to establish the repeatability.
