Transcript abundance of key genes in the stem base of Petunia hybrida cuttings during adventitious root formation in response to nutrient application. (A) CYCLINB1, (B) CYCLIN2, (C) IRT1, (D) FRO2, (E) AMT1, (F) FERRITIN, (G) NAS. Each data point represents the mean±SE of three independent biological replicates of the fold-change related to the initial transcript level at the time of excision. Significant differences to control treatments at specified time points after excision are indicated by asterisks (t-test, *P<0.05, **P<0.01).
