Salinity is an abiotic stress that reduces the seed germination and productivity of wheat. The objective of this study was to assess the impact of irrigation with magnetically treated seawater on the germination, growth, certain physiological and anatomical parameters, and production attributes of wheat ( L.) cv. Sakha 93 plants. Experiments were conducted in the Experimental Farm of the Faculty of Agriculture, Menoufia University, Egypt, during two consecutive winter seasons. Pot experiments involved ten treatments with non-magnetized and magnetized water with various degrees of salinity. Plant samples were taken 95 days after sowing. Irrigation with magnetically treated seawater was found to have beneficial effects on plant growth, water relations, biochemical characteristics, and yield components compared with untreated plants. The germination of wheat seeds increased 13% when treated with magnetic seawater. On the yield scale, the spike length was increased by 40% in season one, and 82% in season two when compared to the control, while the weight of 100 grains increased by 148% and 171%, in each season, respectively, when treated with magnetic water. The anatomical leaf and stem parameters of the plants were markedly improved by watering with magnetically treated seawater at 10 dS m compared to the control. However, the leaf water deficit, transpiration rate, and abscisic acid content in the plant shoots decreased significantly ( < 0.05). The use of magnetically treated seawater of up to 7.5 dS m, instead of tap water, is recommended due to benefits to germination and seedling parameters, growth, yield, and physiological, chemical, and anatomical characteristics. In conclusion, magnetic treatment of seawater improved germination performance, growth, and yield of wheat under saline conditions.
盐度是一种非生物胁迫，会降低小麦的种子发芽率和生产力。本研究的目的是评估用磁处理海水灌溉对小麦（L.）品种Sakha 93植株的发芽、生长、某些生理和解剖参数以及生产特性的影响。实验在埃及梅努菲亚大学农学院实验农场连续两个冬季进行。盆栽实验涉及十种处理，使用不同盐度的未磁化水和磁化水。播种95天后采集植物样本。与未处理的植株相比，发现用磁处理海水灌溉对植物生长、水分关系、生化特性和产量构成因素有有益影响。用磁海水处理时，小麦种子的发芽率提高了13%。在产量方面，与对照相比，第一季穗长增加了40%，第二季增加了82%，而用磁水在每个季节处理时，百粒重分别增加了148%和171%。与对照相比，用10 dS m的磁处理海水浇灌时，植株的叶片和茎的解剖参数得到显著改善。然而，植株地上部分的叶片水分亏缺、蒸腾速率和脱落酸含量显著降低（<0.05）。由于对发芽和幼苗参数、生长、产量以及生理、化学和解剖特性有益，建议使用盐度高达7.5 dS m的磁处理海水代替自来水。总之，海水的磁处理提高了盐胁迫条件下小麦的发芽性能、生长和产量。
