Abstract

Ward, C. I., Lardner, H. A. and Jefferson, P. G. 2012. Short Communication: Etiolated growth of hybrid bromegrass ( Bromus inermis × B. riparius ) compared with smooth bromegrass, meadow bromegrass, crested wheatgrass and tall fescue under grazed or nongrazed conditions. Can. J. Plant Sci. 92: 441–445. Etiolated spring regrowth of hybrid bromegrass was compared with smooth bromegrass, meadow bromegrass, crested wheatgrass and tall fescue under beef steer (Bos taurus) grazed or nongrazed conditions in the previous season over 2 yr in 2006 and 2007. Hybrid bromegrass seeded in 2003 had greater energy reserves than old crested wheatgrass (control) and similar reserves to tall fescue and crested wheatgrass. Hybrid bromegrass can be grazed in similar systems as meadow bromegrass and be expected to maintain sufficient energy reserves for spring growth.
