| Abstract | Studies were conducted to establish some characters which could be used, either in the field or in the laboratory, to differentiate between annual ryegrass (Oregon), Lolium multiflorum Lam. , and Linn perennial ryegrass, Lolium perenne L. Vernation, percentage of glumes covering the spikelets, and height of seedlings seem to be fully reliable characters to differentiate the plants under study. Texture of the tillers, blade width, spikes length, spikelets length, glume length, callus shape of the rachilla, and rachilla length, seem to be relatively good characters for differentiating these species. Number of tillers, embracement of the auricles, number of spikelets per spike, teeth on the lemma, awns on the lemma, and weight of the seedlings are inadequate characters to differentiate between the species studied. Leaf color might be a useful guide to detect contamination, when the species are grown under identical conditions. |
