Summary

The reduction in the contents of chlorophyll in virus diseased pigeon pea leaves was observed to be as high as 60·9 per cent. Carotene and xanthophyll contents of diseased leaves also showed a decrease. The activity of chlorophyllase was increased due to virus infection. The total carbohydrate contents of diseased leaves were reduced. The synthesis of sucrose in diseased leaves was at a lower rate than in the healthy. This reduction in the ability to synthesize sucrose indicated a derangement of photosynthetic activity in diseased plants. Evidences were obtained to show that the translocation of sugars was reduced and that the nature of sugars translocated was altered in the diseased plants.
