Biochemical changes in mothbean leaves infected with Cercospora leaf spot pathogen Cercospora canescens

The maximum phenol content (6.69 mg g-1fr.wt.) was recorded in the diseased leaves of RMO-40 variety compared to healthy leaves. Similarly, highest total sugar (14.29 mg g-1fr.wt.), non-reducing sugar (5.54 mg g-1fr.wt.) and reducing sugar (8.75 mg g-1fr.wt.) content was determined in healthy leaves of RMO-40 variety compared to diseased leaves. Besides highest protein content (15.70 mg g-1fr.wt.) was estimated in diseased leaves of same variety. Based on physiological changes, highest total chlorophyll content (1.55 mg g-1fr.wt.) was observed in healthy leaves of RMO-40 variety as compared to diseased leaves of other susceptible varieties. Highest proline content (1.16 mg g-1fr.wt.) was recorded in the diseased leaves of RMO-40 variety compared to healthy leaves.
