In this study, we investigated the effect of plasma-activated liquids (PAL) on the cotton plant ( L.) growth under laboratory and field conditions. We used two types of PAL: deionized water activated with plasma generated using a microwave plasmatron in atmospheric-pressure air flow (PAW) and a 1.5% KNO solution activated using plasma generated in an electrochemical cell (PAKNO). These treatments differ in terms of their content of long-lived biologically active compounds. PAW contains a higher concentration of hydrogen peroxide (150 μM compared to 1.1 μM), while PAKNO is more saturated with NO and NO (1510 μM compared to 300 µM). We found that PAW improved cotton plant growth under field conditions and in a laboratory drought stress. Additionally, PAW increased field emergence and germination of heat-treated cotton seeds in the laboratory. It was revealed that PAW prevents the drought-induced disruption of the partitioning of absorbed light energy in the photosynthetic apparatus. Meanwhile, PAKNO has a positive effect on seed germination. The positive effect of PALs on cotton seeds and plants is thought to be due to the generation of long-lived biologically active oxygen and nitrogen species during plasma treatment of the liquid.
在本研究中，我们调查了等离子体活化液体（PAL）在实验室和田间条件下对棉花植株（棉属）生长的影响。我们使用了两种类型的PAL：在常压气流（PAW）中用微波等离子体发生器产生的等离子体活化的去离子水，以及在电化学池中产生的等离子体活化的1.5%硝酸钾溶液（PAKNO）。这些处理在其长寿命生物活性化合物的含量方面有所不同。PAW含有较高浓度的过氧化氢（150μM，而相比之下为1.1μM），而PAKNO则更富含NO和NO（1510μM，而相比之下为300μM）。我们发现，PAW在田间条件下和实验室干旱胁迫下改善了棉花植株的生长。此外，PAW增加了田间出苗率以及实验室中热处理棉花种子的发芽率。研究表明，PAW可防止干旱诱导的光合机构中吸收光能分配的破坏。同时，PAKNO对种子萌发有积极作用。PALs对棉花种子和植株的积极作用被认为是由于在液体的等离子体处理过程中产生了长寿命的生物活性氧和氮物种。
