Abstract

ABSTRACT 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.

超细气泡可缓解大豆幼苗的渗透胁迫

摘要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（UFBs）促进生长。在本研究中，分析了聚乙二醇6000（PEG6000）对大豆幼苗渗透胁迫的缓解作用，以评估UFB对土壤干旱胁迫下植物的影响。在无营养条件下，随着胁迫强度的增加，施用UFB可以越来越减轻渗透胁迫引起的生长抑制。UFB处理植物的茎生物量（在所有检测的PEG6000浓度下）超过了绝对对照。渗透胁迫下超氧化物自由基（O2−）的产生是对照的1.5倍，而UFB处理的植物表现出与绝对对照相似的水平。通过UFB处理降低O2−可能有助于缓解渗透胁迫。总之，本研究定量地表明UFB在降低大豆幼苗渗透胁迫方面是有效的。

期刊介绍： Plant Production Science publishes original research reports on field crops and resource plants, their production and related subjects, covering a wide range of sciences; physiology, biotechnology, morphology, ecology, cropping system, production technology and post harvest management. Studies on plant production with special attention to resource management and the environment are also welcome. Field surveys on cropping or farming system are also accepted. Articles with a background in other research areas such as soil science, meteorology, biometry, product process and plant protection will be accepted as long as they are significantly related to plant production.
