The experimental results of dielectric barrier discharge (DBD) plasma treatment on barley (Hordeum Valgare L cv. Yusef) seed germination and seedling growth are analyzed and presented. The seeds were exposed to DBD plasma with 40-, 80-, and 120-W powers for 15 s. All treatments showed positive effects on seed germination, seedling growth, and vigor index. The scanning electron microscope (SEM) images and water imbibition evaluations of plasma-treated seeds revealed that the treatments improved water absorption in the seeds. Similar positive improvements were observed for the plasma-treated seeds in the seedling stage. The best germination characteristics were obtained in 80-W DBD plasma, which included an 18.28% increment in total germination percentage, and 13.35%, 66.83%, 38.55%, and 31.93% increment on the seed germination potential, vigor index, shoot height, and root length, respectively. Moreover, the seed germination of the plasma-treated barley was studied after 2, 7, 14, and 30 days of storage, which indicated the desirable effect of plasma over the storage time. It is concluded that the use of cold plasma can significantly improve the germination and seedling growth of barley seeds.

DBD 等离子体对大麦种子萌发和幼苗生长的影响评价

分析并介绍了介质阻挡放电 (DBD) 等离子体处理对大麦 (Hordeum Valgare L cv. Yusef) 种子萌发和幼苗生长的实验结果。将种子暴露于 40、80 和 120 W 功率的 DBD 等离子体 15 秒。所有处理对种子发芽、幼苗生长和活力指数均表现出积极影响。等离子处理种子的扫描电子显微镜 (SEM) 图像和吸水评估表明，这些处理提高了种子的吸水率。在幼苗阶段，等离子体处理的种子也观察到了类似的积极改善。在80-W DBD血浆中获得了最好的发芽特性，其中包括总发芽率增加18.28%，种子发芽势增加13.35%、66.83%、38.55%和31.93%，分别为活力指数、芽高和根长。此外，在储存 2、7、14 和 30 天后研究了经等离子体处理的大麦的种子发芽，这表明血浆在储存时间内具有理想的效果。结论是冷等离子体的使用可以显着提高大麦种子的发芽和幼苗生长。
