| Abstract/Contents: | "A lab study compared the effect of ice cover and ice encasement with a control treatment (no ice) on Poa annua and Agrostis palustris plants. There were no significant differences between the ice cover and ice encasement treatments. Poa annua plants were dead after only 60 days covered with ice. In contrast, Agrostis palustris plants had LT₅₀ values of -26°C after 90 days of ice cover and -16°C after 120 days of ice cover. A related field study compared the effects of: snow cover, snow removed in February, ice cover and ice removed in February for Poa annua and Agrostis palustris plants. Poa annua plants that had been ice covered were mostly dead by late February a period of about 40 days. Agrostis palustris plants in all treatments could tolerate temperatures below -20°C into April. However, plants from plots where the snow and ice were removed had reduced levels of cold hardiness." |
