Abstract
The experiment was conducted under field and laboratory conditions for evaluation of seed germination characteristics in 3 genotypes from two species of Bromus and three species of Agropyron collected from different parts of Iran. Seeds samples were treated with spores of Fusarium graminearum (140×104mland 70×104ml) and F.avenaceum (124×104ml and 62×104ml). Germination percentage, and speed, root/shoot ratio, dry/fresh weight ratio and vigour index were determined in the inoculated seeds as well in control (non-inoculated seeds). Significant differences for the above characteristics were observed between plant species and genotypes and also between 2 Fusarium species. At both densities F.avenaceum, all of traits were decreased in treated seeds in laboratory except for root/shoot ratio. In general, effect of two species of fungi was more on speed of germination and vigor index than on other characteristics. Also more reduction of seed and seedling characteristics caused by the effect of the two fungi species was observed in greenhouse than laboratory condition. Percentage and speed of germination and vigor index were higher in A. intermediumandA. elongatum comparing to other A. desertorum. All seed characteristics of B. persicus1 genotype were lower than B. persicus2genotype and species of B. inermis.
