The improvement of the growth and quality of medicinal plants under stress is of significance, worldwide. The hypothesis was to alleviate salinity stress in Mentha piperita by enhancing nutrient uptake using magnetically treated water, which to our knowledge has not been previously investigated. The objective was to test the effects of magnetized water (using alternating magnetic fields) (main plots, M1-M4 representing control, 100, 200, and 300 mT, respectively), salinity (subplots, S1-S4 representing control, 40, 80, and 120 mM NaCl, respectively), and growth medium (sub-subplots, X1-X4 representing coco peat, palm, coco peat + perlite, and palm + perlite, respectively) on M. piperita nutrient uptake in the greenhouse. The M treatments, especially the 100 and 200 mT levels, significantly increased plant N (1.08%, S3M4X1), P (0.89%, S3M3X1), K (3.23%, S3M3X1), Ca (53.6 mg/kg, S4M4X4), and Mg (39.63 mg/kg, S3M3X2) concentrations (compared with control at 0.71, 0.49, 2.4, 26.63, 1.63) even at the highest level of salinity. Magnetically treated water also significantly enhanced plant Fe and Zn concentration to a maximum of 750 μg/kg (M4S3X1) and 94.67 μg/kg (S4M4X3), under salinity stress, respectively. The single and the combined use of organic and mineral media significantly affected plant nutrient uptake, especially when used with the proper rate of M treatment. If combined with the proper growth medium, the magnetized water may be more effective on the alleviation of salt stress in Mentha piperita by enhancing nutrient uptake.

使用磁处理水增强盐胁迫下的胡椒薄荷的养分吸收

改善胁迫下药用植物的生长和质量在世界范围内具有重要意义。假设是通过使用磁处理水增强养分吸收来减轻胡椒中的盐分胁迫,据我们所知,此前尚未对此进行过研究。目的是测试磁化水(使用交变磁场)(主图,M1-M4 分别代表对照,100、200 和 300 mT)、盐度(子图,S1-S4 代表对照,40、80和 120 mM NaCl)和生长培养基(子子图,X1-X4 分别代表椰子泥炭、棕榈、椰子泥炭 + 珍珠岩和棕榈 + 珍珠岩)在温室中对胡椒的养分吸收。M 处理,尤其是 100 和 200 mT 水平,显着增加了植物 N (1.08%, S3M4X1)、P (0.89%, S3M3X1)、K (3. 23%, S3M3X1)、Ca (53.6 mg/kg, S4M4X4) 和 Mg (39.63 mg/kg, S3M3X2) 浓度(与对照相比为 0.71、0.49、2.4、26.63、1.63),即使在最高盐度水平。在盐胁迫下,经过磁力处理的水还显着提高了植物 Fe 和 Zn 的浓度,最高分别达到 750 μg/kg (M4S3X1) 和 94.67 μg/kg (S4M4X3)。有机和矿物培养基的单一和联合使用显着影响植物养分吸收,特别是当使用适当比例的 M 处理时。如果与适当的生长培养基相结合,磁化水可以通过增强养分吸收来更有效地减轻胡椒的盐胁迫。63) 即使在最高盐度下。在盐胁迫下,经过磁力处理的水还显着提高了植物 Fe 和 Zn 的浓度,最高分别达到 750 μg/kg (M4S3X1) 和 94.67 μg/kg (S4M4X3)。有机和矿物培养基的单一和联合使用显着影响植物养分吸收,特别是当使用适当比例的 M 处理时。如果与适当的生长培养基相结合,磁化水可以通过增强养分吸收来更有效地减轻胡椒的盐胁迫。63) 即使在最高盐度下。在盐胁迫下,经过磁力处理的水还显着提高了植物 Fe 和 Zn 的浓度,最高分别达到 750 μg/kg (M4S3X1) 和 94.67 μg/kg (S4M4X3)。有机和矿物培养基的单一和联合使用显着影响植物养分吸收,特别是当使用适当比例的 M 处理时。如果与适当的生长培养基相结合,磁化水可以通过增强养分吸收来更有效地减轻胡椒的盐胁迫。尤其是在以适当的 M 处理率使用时。如果与适当的生长培养基相结合,磁化水可以通过增强养分吸收来更有效地减轻胡椒的盐胁迫。尤其是在以适当的 M 处理率使用时。如果与适当的生长培养基相结合,磁化水可以通过增强养分吸收来更有效地减轻胡椒的盐胁迫。
