Effects of multi wall carbon nanotube and nanosilver on some ‎physiological and morphological traits of faba bean (Vicia faba L.)‎

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 10 mg/l ‎and T50 index under control treatment، showed the highest significant decrease. ‎
