Abstract

Cell wall degrading enzymes, namely cellulase, were detected in senescence and diseased macerated tissue of capsicum fruit. Their purported role in pathogenicity of Colletotrichum capsici was studied in detail. In situ prodn. of cellulase concn. ranging from 80 - 360 μg was recorded in healthy capsicum fruit during storage. Prodn. of this enzyme increased with an increase in the storage period. Increase in prodn. of cellulase enzyme was recorded in infected tissue from seventh day after inoculation. Increased productions of this cell wall degrading enzyme coincide with disease manifestation and rapid progress of decay on capsicum fruit. Prodn. of cellulase enzyme ranged from 80 - 360 μg. Conidial germination with advance of incubation period and further growth of C. capsici increased the prodn. of cellulase enzyme. Conidia of C. capsici showed a gradual increase in prodn. of cellulase enzyme with an increase in the incubation period. Treatment of capsicum fruit with different concns. of calcium chloride, lactic acid and sorbic acid showed a 100%, 85.1% and 83.2% decrease in prodn. of cellulase enzyme at the concn. of 1000 ppm, 500 ppm and 1000 ppm resp.
