Conteúdo: | The concentration of nutrients in a number of tissues of oranges after infection with citrus blight was studied. The plants tested were oranges (Valencia) grown on lime rootstocks (Rangpur) which were grown in a commercial orchard, located in Bebedouro Country, Sao Paulo, Brazil. Nutrient measurements were taken from 5 plant tissues (bark, trunk wood, root skin, root wood and leaf). Soil samples were taken under each plant utilized on the experiment. As the disease progressed the amounts of N, K, Mg, S, Cu, Fe and Zn in the dry matter of stem bark, N in the xylem dry matter and S, Cu, Mn and Zn in the leaf dry matter increased. The amounts of K in the leaf dry matter decreased with increasing infection. Accumulation of Zn in the bark was the parameter which best represented the evolution of citrus blight..
