Influence of endogenous ABA concentrations on spreading of B. cinerea in intact tomato plants. Tertiary leaves of WT (tomato cv Moneymaker) and sitiens (tomato cv Moneymaker) plants were infected with 10 droplets of 4 μL of spore suspension containing 10⁶ spores mL⁻¹, 0.01 m Glc, and 6.7 mm KH₂PO₄. Data are means of two experiments containing five plants (10 leaves) per treatment. Infections were evaluated 4 d after inoculation by counting the number of spreading B. cinerea lesions on each leaf. Bars with different letters are significantly different with P = 0.05 after a logistic regression.
