Impact of Magnetic Field on Mung Bean Ultraweak Luminescence

The paper studies the impacts on the ultraweak bioluminescence and peroxidase (POD) activity of the mung beans at the different intensities of the magnetic field for certain time through experimental. The results show that the magnetic field strength will boost the luminous intensity and POD activity of the mung beans. When the magnetic field strength is 0.6 T, the performance of the activity of mung beans POD and the luminous intensity is the most obvious. But when the magnetic field strength is more than a certain range the luminous intensity of the mung beans weakens. This shows the increasing of the magnetic intensity of the beans has played an inhibitory effect. At the same time as the magnetic intensity of mung beans over-increases, activity of the POD does no longer increase, but declines. External stimulation can affect plant leaves on the use of solar energy capacity; and the increase of surplus-energy of the leaves can inhibit the light-emitting and affect the photosynthetic performance of leaves.
