Evaluation of the use of silicon and iron nanoform for pre-sowing treatment of <i>Pisum sativum</i> seeds

Relevance. Modern plant growing technologies are associated with the use of nanoparticles for pre-sowing seed treatment. The article presents results studying effect treatment Pisum sativum seeds solutions iron and silicon nanooxides on germination, viability yield plants in conditions Southern Ural. Methods. For seeds, SiO 2 Fe 3 O 4 were used at a concentration 10 –2 , –3 –4 mg/l, as well solution mixture two oxides. Cell was assessed by method Vijayaraghavaraddy, superoxide dismutase activity determined Giannopolitis Ries, catalase, lipid peroxidation malondialdehyde content – Heath Packer, fractional composition proteins Chen. Results. Determination germination P. showed significant stimulation an increase catalase when treated concentrations (up to 83 % 146 %), 111 %) + 47 %). A decrease malonic dialdehyde due its 40 noted. Against background treatment, protein complex changed pool albumins 88 globulins down 9,8 %.
