摘要

针对等离子体活化水（PAW）寿命短的问题，本研究报告了应用超长寿命等离子体活化水处理植物病害的情况。与未经超长效 PAW 处理的莴苣相比，处理过的莴苣溶液中的病原体减少了约 1 log10 菌落形成单位 mL-1，叶面积、叶重、根长和根重分别增加了 75%、20%、108.33% 和 150%。经 PAW 处理的植株的叶片枯萎率/根系死亡率明显低于未经 PAW 处理的植株。此外，过氧化氢酶和β-1,3-葡聚糖酶等病害防御相关酶在 PAW 处理的莴苣中分别提高了 112.5%和 5.13%，植物防御相关基因上调以应对病原体的入侵。

Ultralong‐lasting plasma‐activated water inhibits pathogens and improves plant disease resistance in soft rot‐infected hydroponic lettuce

To address the short lifetime of plasma‐activated water (PAW), this work reports on the application of ultralong‐lasting PAW for plant disease treatment. Compared with lettuce without ultralong‐lasting PAW treatment, the treated lettuce solution showed c. 1 log10 colony forming units mL−1 decrease in pathogens, as well as improvements in leaf area, leaf weight, root length, and root weight by 75%, 20%, 108.33%, and 150%, respectively. The leaf withering/root mortality rate of PAW‐treated plants was significantly lower than those of non‐PAW‐treated plants. Besides, disease defense‐related enzymes, such as catalase and β−1,3‐glucanase, were respectively enhanced by 112.5% and 5.13% in PAW‐treated lettuce, while the plant defense‐related genes were upregulated to respond to the pathogen's invasion.
