Plasma activated water (PAW) was prepared for 10 min to be applied one to five times as a foliar spray to rice plants, to investigate plant growth, yield and the concentrations of total soluble protein and sugar in the rice grains produced. The results reveal that (1) the plant height, stem diameter, dry weight, chlorophyll and total carotene concentrations were improved by ∼15%, ∼25%, ∼24%, ∼47% and ∼45%, respectively, with respect to control, (2) defense mechanisms of the plants treated with PAW were improved, (3) concentrations of total soluble protein and sugar were enhanced in the rice grains of PAW treated plants and (4) yield was increased by ∼14%.

制备等离子活化水 (PAW) 10 分钟，以叶面喷洒形式向水稻植物喷洒 1 到 5 次，以研究植物生长、产量以及产生的水稻粒中总可溶性蛋白质和糖的浓度。结果表明：（1）株高、茎粗、干重、叶绿素和总胡萝卜素浓度分别提高了~15%、~25%、~24%、~47%和~45%。控制，(2) 用 PAW 处理的植物的防御机制得到改善，(3) PAW 处理的植物的水稻籽粒中总可溶性蛋白质和糖的浓度增加，(4) 产量增加了约 14%。
