Mango wilt, caused by Ceratocystis fimbriata, is one of the most important diseases affecting mango production. This study aimed to evaluate how plants supplied with potassium (K) respond physiologically to the infection caused by C. fimbriata. Plants were grown in plastic pots containing 58 or 240 mg K/dm of substrate. The disease symptoms were more pronounced in the inoculated plants that were grown at the lower K level (58 mg K/dm). These plants showed higher values of upward relative lesion length (79%), relative lesion length (48%) and radial fungal colonization (40%) compared with those grown at the higher K level (240 mg K/dm). Substantial declines in stomatal conductance, in line with decreases in the internal-to-ambient CO2 concentration ratio and the absence of detectable changes in the chlorophyll a fluorescence parameters, suggest that the decrease in the net carbon assimilation rate of the plants is due, at least initially, to stomatal limitations. High concentrations of potassium, calcium and manganese were found in the stem tissues of plants inoculated and supplied with the highest concentration of K, most likely due to the involvement of these tissues in the local development of defense mechanisms. |
