Magnetism is one of the physical methods affecting water properties. It is considered as an environmental factor that plays a role in the physiological and biochemical reactions. A hydroponic experiment was conducted using four types of treated water (distilled water, magnetically treated distilled water, magnetically treated tap water, and tap water). Tobacco plants (Nicotiana tabacum var. Turkish) were placed in a growth chamber for three weeks. Plants irrigated with magnetically treated distilled water had a significant increase in the physiological parameters including shoot height and root length (P < 0.0001). The same pattern was seen in the photosynthetic rate and protein content, but no significant differences in the stomatal conductance and transpiration rate (P < 0.5601). In contrast, a significant increase of total carbohydrate content was exhibited in plant irrigated with tap water (P < 0.0064). Electron micrographs showed deformed chloroplasts with damaged thylakoid membranes associated with plastoglobules in plants irrigated with tap water and magnetically treated tap water. Lastly, this study suggests that magnetically treated water is an excellent option to improve irrigation methods and thus obtains agricultural production with high efficiency.

磁化水对烟草生长和发育的影响（Nicotiana tabacum var。Turkish）。

磁性是影响水性质的物理方法之一。它被认为是在生理和生化反应中起作用的环境因素。使用四种类型的处理水（蒸馏水，磁处理蒸馏水，磁处理自来水和自来水）进行了水培实验。将烟草植物（Nicotiana tabacum var.Turkish）放在生长室中三周。用磁化蒸馏水灌溉的植物的生理参数显着增加，包括枝条高度和根长（P  <0.0001）。在光合速率和蛋白质含量上观察到相同的模式，但是气孔导度和蒸腾速率没有显着差异（P <0.5601）。相反，用自来水灌溉的植物总碳水化合物含量显着增加（P  <0.0064）。电子显微照片显示，在用自来水和磁处理过的自来水灌溉的植物中，叶绿体变形，类囊体膜受损，质体球相关。最后，这项研究表明，磁化水是改善灌溉方法的极佳选择，因此可以高效地获得农业生产。
