| Abstract/Contents: | "A detailed morphological study of three prairie grass cultivars (Bromus willdenowii Kunth) was conducted under 'vegetative' and 'reproductive' growth conditions (short and long photoperiods) and at different temperatures. Perennial ryegrass (Lolium perenne L.) and Westerwolds ryegrass (Lolium multiflorum Lam.) were compared during vegetative growth. Prairie grass had higher leaf appearance rates (leaves per tiller per day) and lower site filling (tillers per tiller per leaf appearance interval) than the ryegrass species. Tillering rates (tillers per tiller per day) were also lower, except under vegetative conditions at 4 degrees C. Low tiller number in prairie grass was not due to lack of tiller sites but a result of poor filling of these sites. Lower site filling occurred because of increased delays in appearance of the youngest axillary tiller and lack of axillary tillers emerging from basal tiller buds. In prairie grass, no tillers came from coleoptile buds while only occasionally did prophyll buds develop tillers. Low tiller number in prairie grass was compensated for by greater tiller weight. Prairie grass had more live leaves per tiller, greater area per leaf and a high leaf area per plant. Considerable variation between cultivars was found in prairie grass. The cultivar, 'Bellegarde' had high leaf appearance, large leaves and rapid reproductive development, but had low levels of site filling, tillering rate, final tiller number and herbage quality during reproductive growth. 'Primabel' tended to have the opposite levels for these parameters, while 'Grasslands Matua' was intermediate and possibly provided the best balance of all plant parameters." |
