Bloom-delaying effects of ethephon (ET) on peach cultivars. Comparison of blooming between the untreated controls and ethephon treatments of ‘Redhaven’ (A) and ‘Sunhigh’ (B), with photos taken at full bloom of the controls (24 March 2020). Blooming progression of ‘Redhaven’ (C) and ‘Sunhigh’ (D) as affected by ethephon, and blooming rate calculated as the ratio of number of flowers to the number of buds on tagged branches. Each point represents the mean of size n = 12. Asterisks ** and *** indicate significant difference between ET treatments and the control at p < 0.01 and 0.001, respectively. ET, ethephon; LF, leaf fall.
