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

研究了微波及高压静电场处理番茄种子所产生的生物效应。测量了番茄种子的相对电导率、出苗率,番茄幼苗的株高、茎粗、过氧化物酶活性、光合色素含量以及叶绿素荧光动力学参数。测量结果表明,适当剂量的微波及高压静电场处理,能有效降低番茄种子的相对电导率,最多下降10.28个百分点。种子出苗率,幼苗的株高、茎粗、过氧化物酶活性、叶绿素含量、叶绿素荧光动力学参数FvFm与FvF0均比对照组有所提高,最大提高值分别为58.3%、175.3%、92.9%、161.6%、54.5%、15.5%和72.78%。试验发现,微波及高压静电场对番茄种子产生生物效应的特点有所不同,说明微波及高压静电场生物效应的物理机理有所不同,为进一步研究微波和静电场生物效应的物理机理提供了试验基础。

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Fmand FvF0of 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.
