effect of magnetic salinated water on some morphological and biochemical characteristics of artichoke (cynara scolymus l.) leaves

plants for optimal growth requires absorb water and nutrients absorption from the soil. magnetic water downward movement of minerals and makes it easy for plants to absorb nutrients and water. this study was designed to investigate the effect of magnetic salt water on some quantity and quality characteristics of artichoke leaves. the experiment was factorial based on completely randomized design with four levels of magnetic field [0, 3000, 6000 and 10000 gauss] and four levels of salinity [0 , 3, 6 and 12 ds/m sodium chloride]. results showed that the magnified water affected plant growth parameters. fresh and dry weight of leaves and roots of plants increased as irrigated by magnified water. a significant interaction of salinity and magnetism was observed on mentioned parameters.salinity and electromagnetic had significant effects on the most measured biochemical parameters. the highest amounts of phenolic and flavonoid contents were observed in the plants treated with magnified and saline water at medium level. the maximum antioxidant activity was observed in plant grown under 6 ds/m salinity. the highest and lowest amount s of chlorogenic acid was observed in plants irrigated with 6 ds/m saline water in which magnified fewer than 3000 gauss. the highest amount of caffeic acid [0/0044 mg/g] was recorded under 6 ds/m salinity and 3000 gauss electromagnetic conditions. based on the results, it can be stated that the magnification increases efficiency of salty water and improve the performance and quality of the artichoke leaves.
