Stomatal opening in plants treated with (Z)-3-hexenyl-butyrate (HB). (A) Time course analysis of the (HB) effect on tomato stomata closure. Stomata ratios were analyzed in non-treated (control) and HB-treated (HB) tomato leaves at 0 (T0), 6, 10, 24, 48, 72 h post-treatment (h), and at 7 and 10 days post-treatment (d). (B) Effectivity of HB treatments in different species. Samples were collected 24 or 48 h after treatments. Asterisk (*), double asterisks (**) and triple asterisks (***) indicate significant differences between control and HB-treated plants with p < 0.05, p < 0.01 and p < 0.001, respectively.
