Year: 2025

Abstract: Metal nanoparticles show various physiological effects on stressed plants. Silicon oxide nanoparticles may promote plant growth and antioxidant resistance, while copper oxide nanoparticles can worsen stress and are less effective in improving plant resistance. However, little is known about the effects of the Al 3+ in soybean plants. This study investigated the effect of silicon nanoparticles and calcium ions on the response of soybean genotypes to oxidative stress under excess aluminum. Interaction and combined effect of silicon nanoparticles 5 mg/L with a diameter of 15 nm and Ca 2+ ions 1 mM on further improvement of growth and reduction of oxidative stress in soybean oil seeds of the William cultivar under Al 3+ stress in hydroponic culture media. For this purpose, antioxidant and physiological responses and growth and biochemical changes of soybean plants under experimental treatments containing Al stress, nanoparticles, and calcium were investigated in a standard greenhouse environment. The results showed that the application of silicon nanoparticles combined with calcium influenced growth parameters (leaf surface and leaf pigments) and total protein due to reduced oxidative stress caused by Al 3+ toxicity on William’s soybean plant. In addition to silicon nanoparticles and Ca 2+ to the medium containing Al 3+ stress, the correlation between the plasma membrane and reduction of Al 3+ absorption was obtained. The findings suggest that the William cultivar exhibits a good response to nanoparticles and Ca 2+ under Al 3+ stress.
