Abstract
Seedlings of crested wheatgrass (Agropyron desertorum (Fisch. ex Link) Schult.), cult Summit, slender wheatgrass (Agropyron trachycaulum (Link) Malte), cull Primar, pubescent wheatgrass (Agropyron trichophorum (Link) Richt.), cult Greenleaf, and quack-grass (Agropyron repens (L.) Beauv.) were grown in the greenhouse for 6 weeks. Each week 20 plants of each species were harvested for growth analysis. Dry weight accumulation in A. trichophorum and A. repens exceeded that in A. desertorum and A. trachycaulum, although net assimilation rate and relative growth rate did not differ among species. A. trichophorum excelled in total weight of roots, total leaf weight, leaf area, and leaf area ratio; A. repens excelled in total sheath weight, total weight of topgrowth, and percent total nonstructural carbohydrates. We suggest that the desirable characteristics of A. repens should be utilized in Canadian grass-breeding programs.
