The effective quantum yield of PSII photochemistry (ΦPSII) before (control) and after 30, 120 and 240 min of B. cinerea aquatic spore suspension application on tomato leaflets, measured at 230 μmol photons m−2 s−1 (a), and at 900 μmol photons m−2 s−1 (b). Error bars are standard deviations (n = 6). Columns with different letters are statistically different (p < 0.05).
