Abstract :

Enzyme response in cassava plants grafted with Srilankan cassava mosaic virus infected scion have been investigated at different intervals of time. It was observed that the enzyme activity of defense related enzymes was higher in virus inoculated plants compared to the healthy plants.The activity was found to increase at all stages in case of both healthy and infected plants. Peroxidase (PO), Polyphenol oxidase (PPO) and Phenyl alanine ammonia lyase (PAL) activities increased and reached the peak value on 60th day after inoculation. Grafted plants exhibited maximum activity for all the enzymes.
