Analysis of defense related enzymes in Chilli Genotypes Infected with Root-Knot Nematode (Meloidogyne incognita)
To determine the defence enzymes activity in chilli varieties against M. incognita an experiment was laid out. The enzyme (PO, PPO, PAL and SOD) activity was analyzed in resistant variety (Pusajwala and NP 46-A) and susceptible variety (S-5 and Ghoomar) of chilli. The roots of inoculated and un-inoculated plants were analyzed after 7, 14, 21, 28 and 60 days after transplanting. Enzyme activity was observed maximum in resistant as compared to susceptible varieties which was increased after root-knot nematode infection. The highest activity of enzymes was found between 21 and 28 days after transplanting. Among all the treatments, resistant varieties of chilli were found to be the best in highest enzyme activities, improving plant growth character and reducing nematode population over other treatment.
