Abstract : Ripe and semi-ripe mango fruits were separately inoculated with Rhizopus arrhizus and Botryodiplodia theobromae and the activities of polymethylgalacturonase, polygalacturonase and cellulolytic enzymes were assessed in fruit extracts. Inoculated ripe fruits had the highest enzyme levels. It is suggested that this is due to a reduction in the concn or activity of cell wall degrading enzymes which are present in semi-ripe fruit.
