Water molecules can be affected by magnetic fields due to their bipolar characteristics. In the present study an experimental maize field was irrigated with magnetically treated water. Tap water was passed through a locally designed alternative magnetic field generating apparatus (110 mT). The maize plants were irrigated by the magnetically treated water from sowing to the seedling stage. Treatment with magnetically treated waterincreased the shoot and root lengths, fresh and dry weight of seedling (30%, 19.1%, 22% and 22%, respectively), compared with the control groups. The contents of photosynthetic pigments, total sugar and total protein of the leaves did not show significant differences between the treated plants and the control group. The ratio of Fv/Fm of seedling and growth parameters of second family were increased, compared to those of non-treated ones. The combined results suggested that the treatment of water a magnetic field with represents a plausible candidate for the mediation of MF effects on plant cells.

In this study cell growth, some physiological parameters, production of Taxol and gene expression in cell culture of hazel under effect of the magnetic field were investigated. Cells in suspension culture were treated by a 30 mT static magnetic field on days 8-11 after subculture and 4 hours each day. The results showed that while the growth rate and viability of cells weren’t affected by the magnetic field but membrane lipid peroxidation rate and H2O2 production increased. Activity of phenylalanine ammonia lyase, polyphenol oxidase and peroxidase enzymes was increased by the magnetic field compared with control. Production of phenolic compounds and Taxolin treated cells showed an increase compared to those of control cells. Magnetic field increased intracellular Taxol more than extracellurTaxol, and in treated cultures total taxol production was 2.9-fold compared to control culture. Gene expression of 1- deoxy -D- xylulose -5 - phosphate reductoisomerase involved in producing Taxol precursors and in its biosynthesis was also increased in treated cells compared to control. It appears that magnetic field by stimulating cell defense responses and inducing gene expression involved in Taxol biosynthesis has resulted in improved its production.
