  "main_findings": "Magnetic field treatment improved Leymus chinensis seedling growth and enhanced saline-alkali tolerance. It increased peroxidase (POD) activity and induced an additional POD isozyme band on electropherogram. The abstract reports 300 mT and 200 mT for 10 minutes as optimum magnetic field intensities for seeds.",
