Effects of XF treatments on ROS production and infection rate of Pst on wheat leaves. a Histological observation of H2O2 accumulation after DAB staining in wheat leaves. SV, substomatal vesicle. Bars = 20 μm. b, c The ROS area of wheat leaves (b) and the infection rate of Pst (c) in the various treatment groups. Only infection sites where substomatal vesicles had formed over stomata were considered successful infections and were microscopically observed for the presence or absence of haustoria. The infection rate was calculated as the number of penetration sites that exhibited one or multiple haustoria in relation to the total number of stomata. Values in the chart are mean ± SD. By Duncan’s new multiple range tests, different lowercase letters indicate differences with significance level 0.05
