Figure 6
Phenotype variations of non-dwarf and dwarf progenies after exogenous IAA and GA4 treatments. Branches of dwarf (a) and non-dwarf (b) progenies treated with IAA and GA4, respectively. Bar = 2 cm in (a), 5 cm in (b). Variations of internode length (c), branch length (d), internode number (e) and primary branch number (f) of dwarf and non-dwarf progenies after treated with IAA and GA4. Model of pre- and post-treatment with GA4 on dwarf branches (g). Model of pre- and post-treatment with GA4 on non-dwarf branches (h). Plants without hormone treatments served as controls. Error bars represent mean ± SD. Different letters on the column in (c–f) indicate significance level at P < 0.01.
