| Abstract/Contents: | "The causes and conditions resulting in winter injury associated with ice sheets were studied utilizing three grasses; Poa pratensis 'common', Agrostis palustris 'Toronto', and Poa annua. All vegetative materials were allowed to harden naturally in the field. On November 26, 1962, four-inch plugs were taken and the following treatments were applied: (1) flooding, then freezing, (2) freezing, then applying thin ice layers, (3) freezing, then applying snow later followed by an ice layer, (4) placing in a sealed container and freezing, (5) bulk pressure freezing, (6) no treatment, and (7) submerging in water at 35°F. All treatments were held at 25°F. except for number 7. At fifteen-day intervals, replicated samples from each variety and treatment were removed from the low temperature chamber, thawed, and placed in a 70°F. growth chamber. Results of this study showed that during the 90-day period winter injury by oxygen suffocation, toxic accumulations, cellular leaching, or outward water diffusion into ice were of no significant importance. No injury occurred in A. palustris while some injury was observed in P. pratensis with P. annua intermediate between the two." |
