| Abstract/Contents: | "Livestock and hay producers in temperate climates could greatly benefit from more high-quality, cold-tolerant forage cultivars. Currently in the Midwest, no rotational grazing experiments have been done studying perennial ryegrass (Lolium perenne L.) cold tolerance in both a grass monoculture and a binary mixture with ladino white clover (Trifolium repens L.). The objective of this study was to evaluate cold tolerance of diploid ('Aries' and 'Mara') and tetraploid ('Barfort' and 'Quartet') cultivars of perennial ryegrass. Aries and Quartet are from New Zealand, Mara is from Romania, and Barfort is from Holland. Germination across a range of temperatures was evaluated in the laboratory, using a thermogradient plate to determine if cultivars would germinate equally well as temperatures declined. In the field, grasses were grown as monocultures and as binary mixtures with ladino white clover and rated for winter hardiness at three Michigan field locations. The field trials were monitored during the establishment year (2001-2002 growing season) for winter injury, ground cover, and yield. Both the laboratory and field results showed Barfort as one of the better-adapted cultivars to cold temperatures. Mara was also adapted to cold temperatures in the field, but was poorly adapted in laboratory studies. Both autumn ground cover and first harvest yields correlated closely with amount of winter injury. As the season progressed and the grasses recovered from the winter injury, differences between cultivars were not as apparent. At all three Michigan locations (Hickory Corners or KBS, Lake City, and Chatham), however, Mara was one of the highest yielding cultivars for both first and total yields." |
