Abstract
In order to investigate the effects of nano silver and multi wall carbon nanotube levels on some morphological and physiological traits of faba bean the present study was done. This factorial experiment was conducted in a completely randomized design with three replications and two treatments with four concentrations (0,100,200 and 300 mgl-1). The results showed the total number of seeds germinated, shoot length, root length, shoot weight and dry weight, root weight and dry weight and root tolerance had significant differences at Ag and multi wall carbon nanotube treatments (p<0.01) whereas, T50 and germination rate traits showed non significant differences under nanoparticle treatments. Nanoparticles concentrations had significant effects on Shoot fresh weight and shoot dry weight indices, germination rate and T50 (p<0.05) and shoot length, root length, root fresh and dry weight, root tolerance index and total number of germinated seeds indices (p<0.01). Shoot length and root dry weight under 200 mg/l concentrations, showed significant difference with other treatments and root tolerance, root fresh weight and root length, showed highest significant decrease under 300 mg/l concentration. The interaction effects of treatments, had significant effects on germination rate (p<0.05) and other indices (p<0.01). Root dry weight, root tolerance and number of germinated seeds under 300 mg/l, and germination rate indices under 100 mg/l and T50 index under control treatment, showed the highest significant decrease.
