Effect of the withdrawal of components from full mineral solution on adventitious root (AR) formation in Petunia hybrida. (A) Representative image of rooted cuttings in nutrient-free solution (control), full mineral solution or full mineral solution lacking the indicated nutrients. (B–D) Percentage of rooted cuttings (B), average root length (C), and average number of ARs (D) were each assessed 14 d after excision. Bars represent means+SE of three independent replicates each consisting of ten cuttings. Significant differences are indicated by different letters (Fisher’s LSD, P≤0.05). Scale bar, 1 cm.
