Abstract : The effect of different substrates on the production of pectolytic enzymes by Colletotrichum gloeosporioides [Glomerella cingulata] was studied. Cell walls of tomato induced the highest amounts of both polygalacturonase and pectate lyase. Calcium activated and induced higher amounts of pectate lyase but had no effect on the activation and induction of polygalacturonase. The role of calcium in controlling soft rot diseases and the lack of potential for using calcium in control of anthracnose of mango is discussed.
