The aim of this research was to study the effect of MnO nanoparticles stabilized with L-methionine on the morphofunctional characteristics of the barley ( L.) crop. MnO nanoparticles stabilized with L-methionine were synthesized using potassium permanganate and L-methionine. We established that MnO nanoparticles have a diameter of 15 to 30 nm. According to quantum chemical modeling and IR spectroscopy, it is shown that the interaction of MnO nanoparticles with L-methionine occurs through the amino group. It is found that MnO nanoparticles stabilized with L-methionine have positive effects on the roots and seedling length, as well as the seed germination energy. The effect of MnO nanoparticles on L. seeds is nonlinear. At a concentration of 0.05 mg/mL, there was a statistically significant increase in the length of seedlings by 68% compared to the control group. We found that the root lengths of samples treated with MnO nanoparticle sols with a concentration of 0.05 mg/mL were 62.8%, 32.7%, and 158.9% higher compared to samples treated with L-methionine, KMnO, and the control sample, respectively. We have shown that at a concentration of 0.05 mg/mL, the germination energy of seeds increases by 50.0% compared to the control sample, by 10.0% compared to the samples treated with L-methionine, and by 13.8% compared to the samples treated with KMnO.
本研究的目的是研究用L-甲硫氨酸稳定的MnO纳米颗粒对大麦作物形态功能特征的影响。用高锰酸钾和L-甲硫氨酸合成了用L-甲硫氨酸稳定的MnO纳米颗粒。我们确定MnO纳米颗粒的直径为15至30nm。根据量子化学建模和红外光谱，结果表明MnO纳米颗粒与L-甲硫氨酸的相互作用是通过氨基发生的。发现用L-甲硫氨酸稳定的MnO纳米颗粒对根和幼苗长度以及种子发芽能量有积极影响。MnO纳米颗粒对大麦种子的影响是非线性的。在浓度为0.05mg/mL时，与对照组相比，幼苗长度在统计学上显著增加了68%。我们发现，与用L-甲硫氨酸、KMnO处理的样品以及对照样品相比，用浓度为0.05mg/mL的MnO纳米颗粒溶胶处理的样品的根长分别高出62.8%、32.7%和158.9%。我们已经表明，在浓度为0.05mg/mL时，与对照样品相比，种子的发芽能量增加了50.0%，与用L-甲硫氨酸处理的样品相比增加了10.0%，与用KMnO处理的样品相比增加了13.8%。
