The present study was carried out in order to evaluate the promoting effect of a static magnetic field (SMF) on drought tolerance and medicinal properties in Hyssopus officinalis. In the current work, the effect of seed priming with SMF (45, 90, 200, and 250 mT for 5 min) was investigated in 60‐day‐old hyssop (H. officinalis) plants that were irrigated every 8 days. The assessments consisted of total dry mass, membrane integrity, photosynthetic pigment concentrations, polyphenol content, antioxidant enzyme activities, and antioxidant capacity. Compared with exclusively water stress, magnetopriming, particularly at 200 mT, significantly altered these parameters in the grown plants. At this intensity, the level of total dry mass, total chlorophyll, and polyphenol content increased by 94%, 2.5‐ and 7.7‐fold, respectively. Also, the level of electrolyte leakage and malondialdehyde decreased by 35% and 33%. The reducing power, DPPH (1,1‐diphenyl‐2‐picrylhydrozyl), and superoxide anion‐scavenging activities were highly augmented as well. Magnetopriming at 200 mT increased catalase (+92%) and ascorbate peroxidase (+2.3‐fold) activities. However, the highest activity of guaiacol peroxidase was recorded at 90 mT. Generally, the present study illustrated the positive effect of magnetopriming (200 mT) on improvement of drought tolerance in H. officinalis through protection of cellular membrane integrity, maintenance of photosynthetic pigment content, and alternation of antioxidant enzyme activities. Furthermore, the data showed this treatment (200 mT) not only had no negative effect on medicinal properties of H. officinalis, but also improved it via increasing total phenolic content and antioxidant capacity.

水分胁迫下静磁场对草索（Hyssopus officinalis L.）生长和植物化学性状的改善作用。

进行本研究是为了评估静磁场（SMF）对西番莲（Hyssopus officinalis）的耐旱性和药用特性的促进作用。在当前的工作中，在60天的牛膝草（H. officinalis）中研究了使用SMF（45、90、200和250 mT进行5分钟的种子引发）的效果。）每8天灌溉一次的植物。评估包括总干重，膜完整性，光合色素浓度，多酚含量，抗氧化酶活性和抗氧化能力。与专门的水分胁迫相比，特别是在200 mT时，磁致灌注显着改变了已生长植物中的这些参数。在此强度下，总干物质，总叶绿素和多酚含量分别增加了94％，2.5和7.7倍。另外，电解液泄漏和丙二醛的水平分别降低了35％和33％。还原能力，DPPH（1,1-二苯基-2-吡啶基氢苄基）和超氧阴离子清除活性也大大增强。在200 mT的磁力启动增加了过氧化氢酶（+ 92％）和抗坏血酸过氧化物酶（+2.3倍）的活性。然而，愈创木酚过氧化物酶的最高活性记录在90 mT。总的来说，本研究表明了磁吸引发（200 mT）对提高水稻耐旱性的积极作用。厚朴通过保护细胞膜完整性，维持光合色素含量和改变抗氧化酶活性来实现。此外，数据表明该处理（200mT）不仅对H.officinalis的药用特性没有负面影响，而且还通过增加总酚含量和抗氧化能力改善了它。生物电磁学。2020; 41：403–412。©2020生物电磁学会。
