Abstract :In recent years, studies have shown that uncertainties such as nanoparticle effects on plants, knowledge gaps and toxicity mechanisms have been significantly displayed. In this study physiological effects and the main factors contributing to nano and micro Boron (B) toxicity in duckweed (Lemna minor) under experimental conditions were investigated. This study reports that that chlorophyll contents of treated nano B are higher than the control group and the treated micro B. Malondialdehyde and superoxide dismutase levels were recorded higher in micro B. Catalase and hydrogen peroxide level were recorded higher in nano B. Pearson's correlation analysis showed negative correlations between hydrogen peroxide and malondialdehyde levels in all doses of nano B; Positive correlations were found between malondialdehyde and catalase levels at 100 mg /L of micro B. The accumulation in leaf tissues of the duckweed decreased by the increase in the concentration of nano B. On the contrary, micro B, as the concentration of micro B increases the accumulation of plant tissue.
