Effects of quercetin, sinigrin, campesterol, and β-sitosterol on stomatal apertures in A. thaliana (A,C,E and G) and B. napus (B,D,F and H) leaves. Data are means ± standard errors of at least 4 independent replicates with 100 ± 5 stomata measured for each sample. Asterisks indicate a significant effect of addition of the secondary metabolite (Student’s t test; p < 0.05).
