The Impact of Seed Priming Silver Nanoparticles on Germination Indicators of Durum Wheat (Triticum durum L., var. Sham 7)

Abstract

Laboratory experiment was conducted in the College of Agricultural Engineering at Al-Furat University in Deir Ez-Zor. The seeds of durum wheat (Triticum durum L., var. Sham 7) were soaked before planting in Petri dishes with two solutions: silver nanoparticles (Ag NPs) and regular silver nitrate (AgNO3) at four concentrations (10-20-40-80 ppm) in addition to soaking in distilled water (control treatment) for a duration soaking of 1,2 and 3 hours. Silver nanoparticles were synthesized by green methods from extract of dried Eucalyptus camaldulensis leaves and the resulting silver nanoparticles exhibit a spherical shape with dimensions of 12 nanometers as described by scanning electron microscopy (SEM). The surface plasmon resonance peak at a wavelength of 450 nm is based on UV-Vis spectroscopy. The results of seed soaking experiment indicated that the seed soaking of durum wheat before planting in silver nanoparticles (Ag NPs) or regular silver nitrate (AgNO3) for two hours had a significant effect on the studied germination indicators (germination rate, germination percentage, shoot length, root length, dry weight of shoots and roots). The values were higher when seeds were soaked in a 20 and 40 ppm of silver nanoparticles. The study recommends to soaking wheat seeds in a solution of silver nanoparticles at a concentration of 20-40 ppm for two hours before planting, also recommends to conducting several seed priming experiments with different nanomaterials for other varieties and crops.
