The effects of magnetic treatment on nitrogen absorption and distribution in seedlings of Populus × euramericana 'Neva' under NaCl stress.

ABSTRACT: A potted experiment with Populus × euramericana 'Neva' was carried out to assess whether there are positive effects of magnetic treatment of saline water (MTSW) on nitrogen metabolism under controlled conditions in a greenhouse. Growth properties, nitrogen contents, enzyme activities and metabolite concentrations were determined based on field experiments and laboratory analysis after a 30-day treatment. The results were as follows: (1) Biomass accumulation, root morphological properties and total nitrogen content were improved by MTSW. (2) Magnetization led to a greater increase in nitrate-nitrogen (NO₃^--N) content in roots than in leaves, accompanied by greater NO₃^- efflux and activated nitrate reductase. (3) MTSW led to a higher ammonium-nitro
