Abstract/Contents:"The utilization of impermeable covers on annual bluegrass (Poa annua var. reptans) golf greens as an element of winter protection is increasing rapidly in Canada. Plant damage not related to low temperatures or excess water has been observed under impermeable covers. It is hypothesized that these damages may result from the modification of the atmosphere at the plant level by the presence of the covers. Very little is known regarding the gaseous composition of the atmosphere underneath impermeable covers (ice, plastic sheet, etc.) during winter. Our objective was to characterize the gaseous composition of the atmosphere underneath impermeable covers during the winter and the tolerance of annual bluegrass to such conditions. Experiments conducted during three winters on golf greens have lead to the following observations: 1) Anoxic conditions (<1% O2; >10% CO2) can develop in less than 60 d after the installation of protections; 2) Annual bluegrass can survive exposure to anoxia for a period of at least 40 d; 3) On some greens, anoxia can lead to highly reductive conditions and death of annual bluegrass; 4) Problem greens present higher soil respiration an that non problem greens; 5) Higher soil respiration is related to higher soil organic matter content."
