Fig. 7. — Effect of foliar or basal application of iron on adventitious root (AR) formation in Petunia hybrida. (A) Representative image of the rooted cuttings in response to foliar or basal application of Fe compared with control conditions. (B) Chlorophyll a or b concentrations in mature leaves shown as the mean+SE of five independent replicates, analysed 14 dpe. (C–E) Percentage of rooted cuttings (C), average root length (D), and average number of ARs (E) were 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, 200 µm.
