Abstract The magnetic fields are one of the effective environmental factors on biological phenomena in living organisms especially plants. Artichoke (Cynara scolymus L.) is a medicinal plant that plays a good role in blood cholesterol reduction and liver disorders, this study has performed to investigate the effectiveness of magnetic water on growth, fresh and dry weight of leaf and root, efficiency of the water consuming and some chemical compounds of Artichoke plant in 2012. Experimental treatments include of four levels of electromagnetic field intensity (Zero, 3000, 6000 and 10000 Gauss) as a complete randomized design with four replications. Analysis of variance of data revealed that plant growth, shoot weight, root weight and efficiency of water consuming and chemical compounds were significantly influenced by irrigation with magnified water. The highest Phenol and Antioxidant activity of plant extract was observed in samples which were irrigated with water in which magnified with 6000G magnetic field with 3.99 mg/g and 66.74%, respectively. Contrast to that the highest amount of chlorogenic acid (0.20 mg/g) was observed in samples which were irrigated using top water. Based on the obtained results Therefore, it is concluded this level (6000G) of intensity has better effectiveness in comparison to other level on quality of Irrigation water and could increase quality Artichoke plant.

Abstract Artichoke (Cynara scolymus) is one of the oldest herbs and nowadays because of its ‎ingredient is concerned by pharmaceutical industry. Abiotic stresses including salinity, ‎changes the metabolic pathways of cultured cells and leads to the production of secondary ‎metabolites. This study was aimed to determine the effect of salt stress on antioxidant ‎compounds of callus focusing on the phenol, flavonoid, and chlorogenic acid and caffeic acid ‎production under in vitro conditions. The present study was carried out as two separate ‎experiments as direct culture (cultured explant) on MS solid medium with different salinity ‎concentrations (0, 50, 150, 300, 600, 1200 µM NaCl) and indirect culture (callus culture) in ‎different salin concentrations of 0, 50, 150, 300, 600, 1200, 2000, 4000, 6000 and 75000 µM ‎NaCl. Four weeks after culture the mentioned compounds were measured via distinctive ‎methods. Results showed that, versus to indirect culture radical scavenging percentage, the ‎content of chlorogenic acid and caffeic acid were significantly influenced by salinity and the ‎highest amount of them were recorded in the samples in which treated with 300 µM NaCl, ‎control and 600 µM NaCl, respectively. In indirect culture no significant difference was ‎observed on other phenolic compounds and antioxidant activity except caffeic acid.
