Floral development in response to ethylene exposure in Campanula. Visual presentation of flower responses to ethylene concentrations of 0, 0.05 or 0.1 μL · L−1 ethylene for 72 h a C. portenschlagiana (Cp), b C. formanekiana (Cf), c C. medium (Cm). Graphical presentation of flower senescence (%) in responses to ethylene concentrations of 0, 0.05 or 0.1 μL · L−1 ethylene for 0–72 h d Cp, e Cf, f Cm. Flower senescence were monitored every 24 h for 1-day (black) and 4-day (grey) old flowers. Data are means ± SE. Values with same letters within species and are not significantly different (P > 0.05). Values with same symbols between species are not significantly different (P > 0.05)
