The activity of superoxide dismutase and peroxidase enzymes under the influence of water and irrigation intervals to ornamental periwinkle

To investigate the effect of magnetic water on the periwinkle a factorial experiment based on CRD carried out with 16 treatments in three replications. Treatments consisted of four types of water (magnetic tap water, the tap water, magnetic well water and well water) and four irrigation intervals (2, 4, 6 and 8 days). The results showed the least time to flowering periwinkle (45.20 days), the highest number of flower (17.96), the highest number of leaves (165.88), the maximum number of branches (17.44), maximum height (21.71 cm), maximum diameter of the stem (6.95 mm) and lowest ionic leakage (55.96%) were found in treatment of 2 days and magnetic tap water. The minimum MDA observed in interval irrigation of 2 days with magnetic well water and magnetic tap water. The maximum MDA obtained in irrigation intervals of 8 days tap (9.7 nmol g F.W-1) and well water (9.45 nmol g F.W-1), respectively. The highest and lowest activity of SOD were found in irrigation intervals of 8 days with magnetic well water (59.75 IU. g D.W-1) and irrigation intervals 2 days with well water (10.86 IU. g D.W-1). Maximum POD activity (6.04 nmol g F.W-1) was observed in irrigation of 6 days with well water.
