Effects of low- and high-UV irradiance on (A) number of leaves, (B) stem length, and (C) density of type-VI glandular trichomes in the tomato genotypes ‘Moneymaker’, ‘Castlemart’, defenceless-1 (def-1), and odorless-2 (od-2) at 28 d after the beginning of treatment (applied for 30 min d⁻¹). Data are means (+SEM) of n=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.
