Enzyme activities of agarwood (Aquilaria malaccensis Lamk.) stem under pathogenesis

Cellulase, pectinase, peroxidase and polyphenol oxidase activities were determined in healthy,naturally infected and inoculated agarwood (Aquilaria malaccensis) plant parts at varioustime intervals to study the changes in activities of these enzymes during pathogenesis.  Samplesinfected naturally with Chaetomium globosum and  Fusarium oxysporum exhibited higheractivity of all the enzymes compared to healthy samples
