New data on the effect of colloidal silicon nanoparticles on the content of nutrients and photosynthetic pigments in tomato plants invaded by root-knot nematode Meloidogyne incognita are presented. Foliar treatment of plants with colloidal solutions of silicon nanoparticles at concentrations of 0.5 and 1.0 μg/mL revealed an increase in the content of photosynthetic pigments and a number of biogenic elements (P, Mg, K, S, and Fe) in tomato leaves, indicating an improvement in the physiological state of the invaded plants. The stimulating effect of nanosilicon on the development and growth of plants and the inhibiting effect on the susceptibility of plants by nematodes and the morpho-physiological parameters of the parasite is shown.
现提供关于胶体硅纳米粒子对受根结线虫侵染的番茄植株营养物质和光合色素含量影响的新数据。用浓度为 0.5 和 1.0 μg/mL 的胶体硅纳米粒子溶液对植物进行叶面处理，发现番茄叶片中的光合色素和一些生物元素（P、Mg、K、S 和 Fe）的含量增加，表明受侵染植物的生理状态得到改善。纳米硅对植物的发育和生长具有刺激作用，对植物的易感性和线虫的形态生理参数具有抑制作用。
