INFLUENCE OF IRON OXIDE NANOPARTICLES AND COMPLEXES OF BIOGENIC METALS WITH ORGANIC ACIDS ON PHYSIOLOGICAL AND BIOCHEMICAL CHARACTERISTICS OF WHEAT SEEDLINGS

In this study, complexes of manganese (II) and zinc(II) with ligands (salicylic acid cysteine) [MnL2(H2O)2]2H2O, [ZnL2(H2O)2]2H2O have been synthesized. It is shown that the composition obtained depends on ratio initial components. The structure studied by elemental, X-ray phase analysis, (DLS)method, UV-VIS spectroscopy, IR spectral thermogravimetric analysis. method UV spectroscopy has show in metal enter neutral form coordinate complexing agent through nitrogen atom. According to d-d transition was observed corresponding wavelength for Mn 480-560 nm, Zn complex 238 nm. results studies final product thermal decomposition all compounds oxide, respectively. zinc amino acids cysteine, methionine, glycine salicylic nanoparticles Fe2 O3 a positive effect seed germination, synthesis photosynthetic pigments activity ascorbate peroxidase wheat leaves
