Effect of IAA treatments on stalk elongation, endogenous hormone content, and related gene expression of flowering Chinese cabbage. Stalk elongation ratio of flowering Chinese cabbage (a). Changes in endogenous IAA (b) and GA (c) content in stalk tips treated with different phytohormones. The relative expression of signal transduction (d,e) genes, polar transport genes (f), IAA biosynthesis (g,h), GA biosynthesis (i,j), and cell expansion (k)-related genes under different phytohormone treatments. Values with different letters indicate significant differences at p < 0.05, according to Duncan’s multiple range tests. Error bars indicate standard errors of three biological replicates. Decap. decapitation treatment.
