Fig. 5.
Effects of UV on concentrations of (A) 12-oxo-phytodienoic acid (OPDA), (B) jasmonic acid (JA), (C) jasmonic acid-isoleucine (JA-Ile), (D) salicylic acid (SA), (E) indole-3-acetic acid (IAA), and (F) abscisic acid (ABA) as determined in control and high UV-treated (applied for 30 min d−1) tomato genotypes ‘Moneymaker’, Castlemart, defenceless-1 (def-1), and odorless-2 (od-2) at 28 d after the beginning of treatment. The analysis was performed on leaflets collected from the third/fourth youngest leaf. Data are means (+SEM) of n=3–5 individual plants and different letters indicate significant differences among groups as determined by GLM followed by Fisher’s LSD test (P≤0.05). The overall effects of genotype (G), UV, and their interaction are indicated on each graph.
