Tóm tắt

This study investigated the effects of a magnetic field (MF) on agronomical and physiological characteristics of Ming aralia (Polyscias fruticosa) under hydroponic conditions. The evaluation focused on key root-related traits, including root length, root hair density, fresh biomass, and dry biomass, as well as leaf-related traits such as leaf area, chlorophyll content, and fresh and dry leaf biomass. Results revealed that MF exposure significantly enhanced root development, with treated plants showing a 21.5% increase in root length, a 48.2% improvement in root hair density, 24.8% and 36% higher fresh and dry root biomass, respectively, compared to the control group at day 50 of treatment. Similarly, leaf traits exhibited substantial improvements with MF treatment, including a 20.2% increase in leaf area and a 20.4% enhancement in chlorophyll content by the end of the experiment. Fresh and dry leaf biomass of the treated group were also 25.2% and 28.1% higher, respectively, than those of the control group. These findings suggested that MF acts as a biophysical stimulus, enhancing both morphological and physiological aspects of plant growth, likely by improving water and nutrient absorption, photosynthetic efficiency, and metabolic processes. The study highlights the potential of MF as a sustainable and effective tool to optimize plant development and productivity in controlled cultivation systems.
