EFFECTS OF RHIZOBACTERIA APPLICATION ON ENZYME ACTIVITY OF DIFFERENT APPLE SCION–ROOTSTOCK COMBINATIONS

By using biofertilizers consisting of beneficial microorganisms instead synthetic chemicals, plant growth is increased, damage to the environment largely prevented and soil fertility preserved. This study was conducted seven standard cultivars (Scarlet Spur, Red Chief, Fuji, Jeromine, Galaxy Gala, Granny Smith, Golden Reinders), which were budded onto M9 MM106 rootstocks commonly used in region. During experiment, nitrogen phosphorus solvent rhizobacteria applied three times over a 15-day period spring. The application had positive impact on catalase (CAT), superoxide dismutase (SOD), peroxidase (POD) activities observed leaves across all scion-rootstock combinations. effect ranged from 4.0% 30.0% for CAT, 5.2% 21.7% SOD, 13.7% 29.1% POD. In this study, very significant results obtained effects enzymatic activity. present may provide leads further studies subject.
