Fig. 6From: Comparative transcriptomic and metabolic analysis of wild and domesticated wheat genotypes reveals differences in chemical and physical defense responses against aphidsTrichome density on wheat seedlings at 11, 15 and 18 days after germination. Bars represent the average number of edge trichomes (a) and the density ± SE of surface trichomes (b) (mean +/− SE, n = 6–8). Different letters above the bars indicate significant differences, using ANOVA followed by Tukey’s HSD test separately for each sampling time. A summary table of the two-way ANOVA results is shown at the top. The inferior numbers indicate the degree of freedom and the total number of samples used for the test. c Images of leaf epidermis showing trichome length and direction (0.6 squared mm area of the leaf)Back to article page
