Figure 5.
Ethephon effects on fruit set and fruit size of peach cultivars. Fruit set (%) of ‘Redhaven’ (A) and ‘Sunhigh’ (B) was evaluated 2, 4, and 6 WAFB. Fruit size of ‘Redhaven’ (C) was measured 2, 4, and 6 WAFB and fruit size of ‘Sunhigh’ (D) was measured 6 WAFB. Each point or bar represents mean ± SE, each of size n = 12 for fruit set, and n = 30 for fruit size. Asterisks *** represent significant difference between ET treatment and the control at p < 0.001. ET, ethephon; LF, leaf fall; WAFB, weeks after full bloom.
