Evaluation of metal nano-particles as growth promoters and fungi inhibitors for cereal crops

Abstract Background Nano-particles of metals can be routinely synthesized. The cereal seeds treatment with the particles improve early growth and crop production. Moreover, is robust economical. Methods Metal (Fe 0 , Cu Co ), zinc oxide (ZnO) chitosan-stabilized silver nano-particles were synthesized applied to seeds. germination rate, plant development inhibition effects on pathogenic fungi quantified. Results It was found that all had a positive effect healthy seedlings. In particular, length above-ground part seedlings increased by 8–22%. highest observed Helminthosporium teres application chitosan-Ag. Pre-sowing metal reduced number infected grains two times for wheat 3.6 barley. also increases chlorophylls carotenoids in both uninfected Conclusions results demonstrated improving Graphical
