A number of metal oxide nanopowders (Fe2O3, ZnO, CoFe2O4, ZnFe2O4) were synthesized in an aqueous extract from the leaves of Petroselinum crispum by a biological method. Physicochemical certification of synthesized nanomaterials was carried out. The data on plant cell viability of the reductases enzyme activity (WST test) were obtained against the background of seed treatment with obtained nanopowders in doses from 10 –3  to 10 –5  M per 4 hours and further short-term action (4, 12 and 24 hours) oxidizing agents (50 μmol H2O2). A following noticeable protective effect was exhibited by CoFe2O4 NPs (pH = 2) and CoFe2O4 (pH=10): cell viability averaged 103, 93, and 92 % respectively. Particles Fe2O3 (84 %) and zinc ferrite ZnFe2O4 both synthesized in an acidic medium (79 %) and alkaline (87 %) had a slightly smaller effect. The remaining nanometals (ZnO, Co3O4) did not have such a strong effect and their reductase activity index was no more than 73 %. The data obtained show the likelihood of using these components in improving the agricultural performance of plants in crop production, improving their growth characteristics and plant productivity.
