Abstract/Contents:Presents a study initiated during 2009 "to determine the temperature degree and duration combinations that result in a loss in freezing tolerance of creeping bentgrass and annual bluegrass." Details methods and materials used during the experiment, noting that "two or three tillers per plant were propagated into cell trays (10 x 20 cm [centimeters]) and maintained in a greenhouse under optimal conditions for three weeks." Notes that "the lethal temperature at which 50% [percent] of the plants were killed (LT50) was determined by curve fitting percent survival to temperature using a four-parameter sigmoid model." Reports that "deacclimation of annual bluegrass and creeping bentgrass was observed in response to 4° C [Celsius], 8° C, and 12° C whether exposed to one day or five days." Concludes that annual bluegrass deacclimated to a greater extent at a lower temperature, which may account for greater susceptibility to freezing injury for this species."

USGA Summary Points:Fluctuations in soil temperatures following cold acclimation can lead to a decrease or complete loss in freezing tolerance, and therefore predispose plants to freezing injury. Deacclimation of annual bluegrass and creeping bentgrass was observed in response to 4° C , 8° C , and 12° C whether exposed to 1 day or 5 days. Annual bluegrass deacclimated to a greater extent at a lower temperature, which may account for greater susceptibility to freezing injury for this species.
