MAGNETIC WATER EFFECTS ON GROWTH AND SOME PHYSIOLOGICAL CHARACTERISTICS OF PAULOWNIA TOMENTOSA THUNB UNDER CADMIUM STRESS CONDITIONS

Paulownia (Paulownia tomentosa) is considered as one of the world's fastest-growing species trees and most widely used for commercial. This research was done a factorial experiment in Koya city, Erbil, Iraq during 2021-2022 to study effects magnetic water (MW) at (0, 500,1000, 1500 2000) gauss cadmium chloride (Cd) 3.33, 6.66 10 mg Kg-1soil) on some growth, physiological biochemical properties this plant. Results demonstrate that MW had non-significant differ regarding survived velocity cutting outgrowth compare using tap water, whereas Cd application increased outgrowth. At least powers significantly each plant leaf-area, stem diameter, shoot root fresh weight dry matter content, well all concentrations plants leaves number, diameter. more roots than shoots, where it has high or matter, compared control treatment. Low power (500 1000) performed better (1500 increasing content photosynthesis pigments. Utilizing greatly enhanced total carotenoids chlorophyll a, b, regardless device power. Chlorophyll (a b) were both reduced by concentrations; however low other treatments. High decreased peroxidase enzyme activity proline percent carbohydrate activity, ascorbic acid comparing control.
