FIGURE 5.

Auxin homeostasis at the stem cutting base is required for AR formation. (A) Graphic representations of rooting stage values in different carnation cultivars and treatments (n = 50). (B) Representative images of adventitious rooting in the studied carnation cultivars at 29 days treated with GH3 inhibitor (10 μM AIEP) or with mock. (C,D) The percentage of cuttings with roots (C) and the area of the scanned root system (D) at 29 days in rooted stem cuttings (n = 50). Dark- and light-colored bars represent data from mock- or AIEP-treated samples, respectively. Different letters indicate significant differences (P < 0.05) over sample means (cultivar × treatment).
