During the evolution procedure, all living cells experienced the step of the natural magnetic fields (geomagnetic fields) ,which is a usual part of their environment. In this experiment, static magnetic fields (SMF) were produced by a locally designed magnetic field generator. This system designed to generate SMF in range of 0.5 mT to 30 mT with stable conditions. The effects of SMF on living cells, specially the influence of MF on germination rate, growth factors and biochemical properties of plant cells, have been the object of several analyses. According to the experiments, magnetic fields (MF) exposure can induce the production of a large amount of biochemical materials in plant cells. The study was focused on the influence of SMF on Almond seeds. The effects of SMF on polysaccharides, proline content, malondialdehyde, peroxidase activity and DPPH were studied in two specious of Amygdalus scoparia and A. eburnea. Unique seeds were selected and divided to dry seeds, the control one and treatment groups. The treatment seeds groups were exposed two a 10 mT SMF for four days. Measurement of polysaccharides content showed that sugar content was lower in treated seeds. MF also increased proline content, peroxidase activity and DPPH in two specious, especially in A. scoparia. According to the present study, A. scoparia is more sensitive to MF than A. eburnea.
