APETALA1 expression in buds and return bloom measurements. qPCR expression of APETALA1 in basal (A) and apical (B) buds collected from untreated peach trees (UTC) and from trees treated with GA₇ at 45, 51, 58, 65, and 79 Days After Full Bloom (DAFB). Letters indicate statistically significant differences (P < 0.05; n = 6) and bars show standard error. A.U., Arbitrary Units. (C) Return bloom reported as a percentage of the UTC. Letters indicate statistically significant differences (P < 0.05; n = 5) and bars show standard deviation
