Increased evapotranspiration promoted leaf wilting development on potato plants. a Representative plant pictures were taken at 4 dpi. “W/T” represents the number of wilted plants with respect to the total number of infected plants. “Open” indicates air exchange conditions while “close” indicates no air exchange conditions. b Bacterial proliferation in potato stems was counted at 4 dpi. Roots of two-week-old potato plants were cut and then inoculated with 1 × 108 cfu/ml of R. solanacearum strain GMI1000. The experiment was repeated twice using 12 plants in each experiment
