高压静电场处理对番茄陈种子萌发活力的影响

Effect of High-voltage Electrostatic Field Treatment on Germination Vigor of Old Tomato Seeds

采用均匀设计方法,研究电场强度和处理时间对番茄陈种子萌发活力的影响,并对其活力指数进行二次回归分析建模,结合直观统计结果,筛选最佳电场处理条件。结果表明:电场强度365.0 k V/m、处理时间31.9 min组合能有效促进番茄陈种子萌发和幼苗生长,种子活力指数达2 198,比未处理种子提高158.6%。

The effects of electrostatic field intensity and treatment time on the germination vigor of old to- mato seeds were studied by uniform design, and the modeled square regression analysis of the vitality in- dex was done, so as to screen the optimum conditions of high-voltage electrostatic field treatment. The re- suits showed that when the electrostatic field intensity was 365.0 kV/m, and the treatment time was 31.9 min, the germination and growth of old tomato seed were improved, the seed vitality index reached the highest value with 2 198,which increased by 158.6% compared to the control.
