Biological Effects of Microwave and High Voltage Electrostatic Field on Tomato Seeds

Biological effects of microwave and high voltage electrostatic field on two kinds of tomato seeds and seedlings were studied.Relative conductivity and germination rate of treated tomato seeds were measured.Relative conductivity of the treated seeds decreased by some degree，maximum by 10.28%.Germination rate of treated seeds was raised by 58.3%，maximum.Such parameters as plant height，stem diameter peroxidase activity，photosynthetic pigments content，soluble sugar content，FvFm and FvF0 of chlorophyll fluorescence parameters of seedlings were also measured.Compared with check samples，these parameters maximum were raised by 175.31%，92.9%，161.6%，54.5%，15.54% and 72.78%，respectively.Biological effects of microwave and high voltage electrostatic field on tomato seeds were different.It meant that the mechanism was different.The study gave us experimental support for the research of bio-effects mechanism of microwave and electrostatic field.
