In this study, the antimicrobial effect of plasma‐processed air (PPA) generated by a microwave‐induced nonthermal plasma was investigated for preharvest utilization using three crop species: Barley, rape, and lupine. Bacillus atrophaeus spores were chosen as a model, inoculated onto seeds, and subsequently treated with PPA at two different flow rates, different filling regimes, and gas exposure times. PPA treatment was efficient in reducing viable spores of B. atrophaeus, reaching sporicidal effects in all species at certain parameter combinations. Maximum germination of seeds was strongly reduced in barley and rape seeds at some parameter combination, whereas it had a modest effect on lupine seeds. Seed hydrophilicity was not altered. Overall, PPA investigated in this study proved suitable for preharvest applications.

在不损害种子发芽的前提下，等离子处理空气对农作物种子进行生物净化的效率

在这项研究中，研究了微波诱导的非热等离子体产生的等离子体处理过的空气（PPA）的抗菌作用，以利用三种大麦，油菜和羽扇豆进行作物的收获前利用。选择萎缩芽孢杆菌的孢子作为模型，接种到种子上，然后以两种不同的流速，不同的填充方式和气体暴露时间用PPA处理。PPA处理可有效减少萎缩芽孢杆菌的活孢子，在某些参数组合下达到所有物种的杀孢子作用。在某些参数组合下，大麦和油菜种子的最大种子发芽力大大降低，而羽扇豆种子的发芽率却不高。种子亲水性没有改变。总体而言，本研究中研究的PPA被证明适用于收获前的应用。
