在次优条件下生长的几种作物中观察到通过应用超细气泡（UFB）促进生长。在本研究中，通过聚乙二醇6000（PEG 6000）缓解渗透胁迫大豆幼苗进行了分析，以评估UFB对植物在土壤干旱胁迫下的影响。在无营养条件下，由于渗透胁迫的生长抑制越来越减轻UFB应用的应力强度增加。UFB处理的植物（在所有检查的PEG6000浓度）的地上部生物量超过了绝对控制。超氧自由基（O2−）的产生在渗透胁迫下是1.5倍，而在UFB处理的植物显示出与绝对对照相似的水平。通过UFB处理减少O2−可能有助于减轻渗透胁迫。总之，本研究定量表明，超滤粉是有效的，在减轻大豆幼苗渗透胁迫。
Growth promotion through application of ultrafine bubbles (UFBs) was observed in several crop species grown under suboptimal conditions. In the current study, mitigation of osmotic stress through polyethylene glycol 6000 (PEG6000) was analyzed in soybean seedlings to assess the effects of UFB on plants under soil drought stress. In no-nutrient conditions, growth suppression due to osmotic stress was increasingly mitigated by UFB application as stress intensity increased. Shoot biomass of UFB-treated plants (at all examined PEG6000 concentrations) exceeded to that of the absolute control. Production of superoxide radicals (O2−) under osmotic stress was 1.5-fold higher than that in the control, whereas that in UFB-treated plant showed a similar level as the absolute control. The reduction of O2−through treatment with UFB may help mitigate osmotic stress. In conclusion, this study quantitatively showed that UFB was effective in reducing osmotic stress in soybean seedlings.
