Cold plasma enhances various biological processes in plants. This study assessed the impact of cold plasma seed treatments on nodulation, root, and shoot growth in pea and lentil under controlled environmental conditions. Seeds were treated with cold plasma generated by a dielectric barrier discharge (DBD) and a pin electrode reactor (PER), with three different exposure durations (3, 6, and 12 min). At 4 weeks, notable enhancements were observed in nodule number and dry weight, root dry weight, length, volume, surface area, and shoot dry weight. The 3‐ and 6‐min exposure using the DBD and the 3‐min exposure using the PER system demonstrated the most significant increases or upward trends in these traits, highlighting the intricate nature of seed–plasma interactions.

冷等离子体种子处理对豌豆 (Pisum sativum) 和扁豆 (Lens culinaris) 结瘤和植物生长的影响

冷等离子体增强植物中的各种生物过程。本研究评估了在受控环境条件下冷等离子体种子处理对豌豆和扁豆结瘤、根和芽生长的影响。用电介质阻挡放电 (DBD) 和针电极反应器 (PER) 产生的冷等离子体处理种子，并采用三种不同的暴露时间（3、6 和 12 分钟）。 4周时，观察到根瘤数量和干重、根干重、长度、体积、表面积和芽干重显着增加。使用 DBD 的 3 分钟和 6 分钟暴露以及使用 PER 系统的 3 分钟暴露证明了这些性状的最显着增加或上升趋势，突出了种子-血浆相互作用的复杂性。
