Influences of Extremely Low Frequency Electromagnetic Fields on Germination and Early Growth of Mung Beans

摘要

This study aims to assess extremely low frequency electromagnetic field (ELF-EMF), which is similar to Schumann resonance (SR) frequency. Schumann resonance frequency which is part of the geomagnetic field frequency, affects to mung beans to increase germination rate and early growth. The aim of the study is to evaluate the effects of SR ELF-EMF on mung beans germination rate and growth rate. SR ELF-EMF pretreatment increases the germination rate since the applied SR ELF-EMF promotes level of Ca^{2+and K+contents. Three groups of mung beans were exposed by SR ELF-EMF of 0.3 mT at swapped frequency$mathbf{7.83} mathbf{Hz} pm mathbf{0.1} mathbf{Hz}$. The experiment results show that germination rates of experimental groups with SR ELF-EMF exposing have 8% to 23.3% higher than control groups. Moreover, the length of stem of the experimental groups have the maximum 14% longer than control groups after 72 hours growth.}
