CONCLUSIONSD
ata obtained in this work demonstrated that Yucaizol exhibits
potent inhibitory activity on the retardation of plant height as
well as the lamina joint bending angle in rice plants. Use of
Yucaizol combined with the GA biosynthesis inhibitor TPE has
a synergistic effect on the retardation of rice seedlings. Our
results suggest that BR and GA may play different roles in
promoting rice plant height when working independently.
