Quantification and effect of JAs during flower opening in peach. (a-b) Total JAs and JA-Ile were quantified in petals of ‘VABM29’ and ‘Glowing star’ at 0% (Stage II) and at 100% anther dehiscence (Stage V). Values are the mean and standard error of three biological replicates. Means in each column having the same letter are not significantly different (P <0.05, Tukey-Kramer HSD test). (c) MeJA (100 μM) or water was sprayed on ‘Glowing Star’ flowers (Stage II) and pictures were captured for the same flower buds at 0, 24, 48 and 72 hours after treatment. (d-e) Measurements for petal surface area (cm2) (d) and anther dehiscence (%) (e) were recorded (n = 12) at the designated times. JA, jasmonic acid; JA-Ile, JA-isoleucine; MeJA, methyl jasmonate.
