CYTOTOXICITY NANOPREPARATIONS USED IN PLANT GROWING

The article deals with the cytotoxicity of nanopreparations witch use to improve agricultural plants research. Investigated the toxicity of nanoagrochemicals: Avatar-1 domestic production, the size of bass element composed of up to 25.8-40 nm and Nano-Gro, whose manufacturer is the company Agro Nanotechnology Corp (USA) with a size of 90 nm NP. Rezultaty cytotoxic effecton the cells of Allium cepa L. showed that the use nanopreparations has disrupted the structure of chromosomes, mitotic spindle damage and change the behavior of chromosomes to the spindle. It is shown that NP toxicity is directly related to their size, which causes a significant chemical activity and high penetration ability. Toxic effects of Avatar-1, compared with Nano-Gro, manifested more that could be due to smaller size bass that are part of it
