A study was undertaken to investigate the effect of magnetic treatment on enzyme activation of paddy seed under laboratory and nursery conditions. A magnetic seed treater having aluminum container fitted with ten 250 gauss magnets on copper pipes in staggered fashion was used. The container could be rotated around the horizontal axis. The dry seeds were treated by putting the seeds in the container and rotated the container for different time periods (15 min without magnet (control) and 15, 30, 45, 60 and 90 min with magnet). In the germinating seeds, enzyme activities of α amylase, β amylase, catalase, and peroxidase were significantly higher in treated seeds as compared to control seeds. Results indicated that α and β amylase activity found higher in treatment T1 (Rotation without magnet for 15 min). Catalase, and peroxidase activities found higher in T5 (rotation with magnet 60 min), T3 (rotation with magnet 30 min) and T3 (rotation without magnet 30 min.) respectively. | Effect of magnetic treatment on enzyme activation of paddy Oryza sativa L.
