THE PERFORMANCE OF WHEAT SEEDS PRIMING WITH SILVER NANOPARTICLES OF VARIOUS COMPOSITIONS: EFFECT OF TREATMENT DURATION AND STABILIZING AGENT
The performance of silver nanoparticles stabilized by various surfactants as agents for nanopriming was evaluated using the seedling method. The nanoparticles at the concentration of 50 mg/l was shown to do not affect the germination energy of common wheat (Triticum aestivum L.) seeds if nanopriming continued 6 and 15 hours, but this indicator reduced by 6-18 percentage points when processed for 24 hours. Nanopriming with all the silver nanoparticles studied led to an increase in the length of the roots and shoots of seedlings and the vigor index of seeds. The optimal priming time was 15 hours, regardless of the type of stabilizing agent of silver nanoparticles. The maximum effect was found for silver nanoparticles stabilized with carboxymethyl cellulose and sodium oleate, characterized by the largest size and absolute value of the electrokinetic potential.
