Abstract : In greenhouse experiments changes in several metabolic parameters soybeans plants after inoculation by P. savastanoi pv. glycinea 9190, X. axonopodis pv. glycines 9192, BCMV, A. laidlawii on background pre-treatment by nanochelates (NHs) of V, Ge, Cu, Mo have been shown. The phenolic compounds content increased in leaves at inoculation by phytopathogens on background pre-treatment by NHs and without it. The content of H2O2 in leaves increased in variants: BCMV (+VNHs, GeNHs, CuNHs), 9192 (+VNHs, CuNHs), 9190 (+GeNHs, CuNHs), A. laidlawii+MoNHs. But it decreased in the variants: BCMV + MoNHs, A. laidlawii + VNHs, 9190 + VNHs, 9192 (+ GeNHs, CuNHs) compared to controls. The peroxidase activity increased in variants: A. laidlawii, 9190, GeNHs + 9190, GeNHs + 9192, CuNHs, CuNHs (+ phytoplasmas, 9192), MoNHs (+ BCMV, phytoplasmas, 9190, 9192) with decreased catalase activity. The content of ABA in the leaves increased in variants: 9190, 9192 (+ VNHs, CuNHs), GeNHs + 9190, but the IAA content reduced. However, on variants MoNHs (+9190, 9192), GeNHs + 9192, A. laidlawii, A. laidlawii (+ GeNHs, CuNHs, MoNHs) the content of both phytohormones was decreased. The content of IAA and ABA in BCMV-infected leaves without treatment was increased, but on background of NHs – it decreased significantly. The Fv/Fm-value increased in almost all variants, except for CuNHs + BCMV. The photosynthetic rate (RFd-value) at inoculation plants with viral, bacterial and phytoplasmas pathogens on background treatment of MoNHs; bacterial strain on background of pre-treatment of GeNHs; phytoplasmas on background of VNHs have been increased. Thus, pre-treatment by nanochelates had regulatory effect on soybean plant metabolism helping increase its resistance to phytopathogens was shown. Thus, pre-treatment by nanochelates had regulatory effect on soybean plant metabolism but the pre-treatment of MoNHs was more effectiveness thanks not only intensification resistance against pathogens but and the assimilation of CO2 increased.
