The effect of magnetic field applications to chemical content of stratified seeds of oriental beech (Fagus orientalis lipsky.)

Abstract

The effects of magnetic field (MF) applied with cold-wet pre-treatment on the chemical components of the oriental beech seeds with physiological deep dormancy are researched in this study. The seeds were subjected to various MF application periods (20, 60 and 120 min) and different MF intensities (200 and 400 mT). Total soluble protein, lipid peroxidation level (malondialdehyde- MDA), total soluble sugars and starch quantities as well as antioxidants such as CAT, SOD, APX and GuPX and α-amylase activity of the seeds were examined. MF application affected protein, lipid, α-amylase and sucrose values positive, starch, glucose and fructose values of the seed negatively. Furthermore, MF applications were found to have an increasing effect on CAT and SOD enzyme activities while having reducing effect on APX and GuPX antioxidant enzymes. It was reached to the conclusion that magnetic field application processes with 400 mT intensity generally increase the seed physiology parameters.
