Fig. 1.

Effect of low and high PAR treatments on tomato resistance to the Western flower thrips F. occidentalis, tested in a whole plant no-choice bioassay, at 35 d after initial light treatments. Silver damage caused by thrips feeding was measured in low and high PAR-treated wild-type (wt) and odorless-2 (od-2) plants at 12 d after thrips infestation. Values represent the mean (� SEM) of 26 plants from three independent experiments. Different letters above bars denote significant differences among groups (ANOVA followed by Fisher’s LSD test, P ≤ 0.05).
