FIGURE 4.

Colonization of plantlets of Vitis vinifera cv. Chardonnay by Aureobasidium pullulans strain Fito_F278 at 0, 4, 7 and 14 days post-inoculation (dpi). Two biological replicates (five pooled plantlets) from each condition and from two experiments are presented. The CFU count was log-transformed and the pooled mean and standard error values of 2 + 2 replicates from the two experiments are presented for each condition. Differences between time points within each plant tissue were compared to determine their significance. Letters indicate significant differences according to the Kruskal–Wallis test, followed by a Mann–Whitney U test (p ≤ 0.05). FW, fresh weight.
