Abstract : Leaves of mango collected at different stages (bronze, pale-green and grown-up) were examined to determine the relationship between the biochemical and physiological properties of the leaves and the occurrence of anthracnose disease (Colletotrichum gloeosporioides [G. cingulata]). C. gloeosporioides infection was more severe on bronze leaves than on pale-green or grown-up leaves. Biochemical assays showed that bronze leaves were covered with less amount of wax and contain less phenolic substances and total soluble sucrose than the leaves collected at other stages. Bronze leaves contained higher amounts of free amino acids.
