Abstract/Contents:"Characterization of hardening and dehardening in Agrostis, Festuca, Lolium, and Poa species and varieties will be presented in terms of: low temperature acclimation and de-acclimation; changes in tissue water content during the hardening process (determined by Nuclear Magnetic Resonance techniques); effect of nitrogen levels during the hardening dehardening period and winter-spring survival. Experiments were conducted under both controlled environment and field conditions in a continental climate (45th parallel N and 93° W longitude). Agrostis species generally developed greatest tolerance to cold followed by Poa, Festuca, and Lolium. Varieties within species varied in ability to tolerate cold stress. 'Toronto', the hardiest creeping bentgrass, developed tolerance to -52°C in January. 'Baron', the hardiest Kentucky bluegrass, tolerated -48°C in January. 'NK 200', the hardiest perennial ryegrass, tolerated -36°C. Other varieties within these species attained different levels of cold tolerance. Onset of cold hardiness development was observed in July in some species while all grasses investigated were least hardy in May-June and hardiest in January. Rapid dehardening was observed under mild winter conditions. A review of the literature and current work on cold hardiness will be included. Physiological effects of cold stress and theories related to cold stress will also be discussed."
