Popis: Resistance is induced in cotton plants as the result of either viral infection or exogenous application of elicitors. Induced resistance can be evaluated by determining the production of β-1,3-glucanase and chitinase in plants as a biochemical parameter. The assays being used for the determination of chitinase and β-1,3-glucanase activity are laborious and not cost-effective, as the reducing sugars produced by the substrates colloidal chitin and laminarin are very expensive. The concentration of both substrates was standardized and reduced to 0.25% from 4% in a modified microplate assay, which appeared to be more effective. The amount of β-1,3-glucanase and chitinase produced was significant and determined by the new modified assay. The sensitivity of the microplate assay was significantly raised approximately one- to twofold.
