Trends in antioxidant enzymes pattern of chickpea grown in healthy plot and sick plot contaminated with wilt disease

Trends in antioxidant enzyme activities were studied in response to fusarium wilt disease (Fusarium oxysporum f.sp ciceri). i.e normal plot (healthy) , while other was kept free for infection of wilt disease in chickpea plants in sick plot. The result obtained from this study was, Chickpea plants at infectional stage (no disease), cultivar showed similar trend as observed at pre infectional stage. At this stage Reactive Oxygen species (ROS) enzymes were also higher. In case of diseased tissues obtained from naturally infected plot, (Infectional stage) showed higher level of oxidative enzymes activity. At post infectional stage, Healthy plants had greater enzyme activities of APX (Ascorbate peroxidase) and SOD (superoxide dismutase). Irrespective of treatments, at pre-infectional stage (S1), susceptible cultivars GG-4 had significantly highest activity of APX followed by JG-62. However, resistant (WR-315 and JCP-27) and susceptible cultivars (JG-62 and JCP-27) did not show any significant change in the activity as disease progress. Disease roots at post infectional had greater amount of APX, and SOD activity. The SOD enzyme in cultivars revealed that the level of activity significantly increased systemically in root tissues with the growth of plant at pre infectional stage to post infectional stage. The activities were varying according to cultivars and infections pattern.
