Abstract:
After buckwheat seeds are treated with different electric field intensity, the biological effect is tested including the effects of electric field on the content of MDA (malondialdehyde), activity of SOD (superoxide dismutase) and POD (peroxidase) in seeding stage and water stress simulated by different concentration of PEG—6000. The results show that under water stress, the electric treatments can delay the accumulation of malondialdehyde(MDA ), promote the activity of superoxide dismutase (SOD) and peroxidase ( POD ) during the stage of seedings, and different intensities of electric field have different effects on buckwheate seeds. In general, 4 kV/cm×15 min and 4 kV/cm×25 min have better effects than others.
