After soaking the seeds of grain crops: winter triticale (Ingen-93 variety), winter wheat (H335 variety) and spring wheat (Arnautka-7 variety) during 6 hours in dispersed solutions of copper nanoparticles (Np-Cu) at different concentrations (from to ) some stimulating effects were revealed in a number of embodiments of the experiment. Germinating energy and seed viability, length of the main root and the stem of the sprout and number of the right sprouts has increased by 50% in comparison with control. Stimulation by certain parameters was even observed in the variant with the lowest nano-Cu concentration (by 31%). Germinating energy and seed viability appeared to be more sensitive to the influence of the nano-factor. Treatment of the seeds by the dispersed nano-copper solutions before their processing with the water suspension of fungi culture Helminthosporium avenae led to reduction of the inhibiting effect of the pathogen. Commonly used for these purposes, 1% solution of potassium permanganate proved itself less efficient. It was revealed the specificity of reaction of each genotype on the exposure to nano-Cu and fungus at the temperature of 25оС. Seeds of the spring wheat were more responsive to the nano-factor. An antifungal effect of Np-Cu on seeds of triticale and winter wheat emerged at some exposure concentrations but on seeds of spring wheat the effect was evident in all the variants. It is planned to use the obtained data to provide a rapid method for pre-sowing seed treatments by nano-particles of copper and of other metals. |
