Measurement of H2O2 and antioxidant contents from floral petals of P30B and NIL. A Appearance of the flowers of P30B and NIL in visible light (upper) and UV light (lower). Scale bar, 2 cm. B UV reflectance in the flowers of P30B and NIL. Value is mean S.D. (n = 10, P ≤ 0.05, one-way ANOVA, Tukey’s HSD test). C Flowers petal temperature of P30B and NIL. Value is mean S.D. (n = 10). D Total extractable flower H2O2 contents in P30B and NIL. Value is mean S.D. (n = 3). E–F SOD activities and POD activities in the P30B and NIL flowers of beauty marker region (BMR) and non-beauty marker region (NBMR). Values are mean S.D. (n = 3). *P ≤ 0.05, **P ≤ 0.01. Student t-test was used to generate P value
