Figure 9: Relative gene expression level of α-expansin genes in leaves of ‘K-31’ and ‘Bonsai’ as affected by GA or TE treatment.

(A) EXPA4; (B) EXPA5; (C) EXPA7. The vertical bar is the standard error of mean (n = 4 replicates of GA or TE treatment, and each replicate contains at least 10 seedlings). Columns marked with different letters indicate significant differences between treatments and between cultivars based on LSD test (P = 0.05).
