DescriptionLow temperature stress is a major abiotic stress affecting many plants worldwide. Cool season and warm season grass species, that are used on high value turf areas, are susceptible to winter injury through chilling or freezing stress, or more commonly through the disruption of cold acclimation. Cold acclimation is a process in which plants are subjected to low temperatures before freezing temperatures to acquire low temperature tolerance. Fluctuating temperatures due to consistently warmer autumn and winter months, cause a disruption in cold acclimation or de-acclimation, resulting in a loss in cold tolerance. Little is known about the pathways of cold acclimation, but a better understanding of the physiological and biochemical changes during the acquisition of freezing tolerance will aid in the development of more tolerant grass species, or better management practices to induce cold tolerance. Research goals were to investigate the physiological and metabolic changes during cold stress that play roles in the acquisition of cold tolerance and induce recovery after freezing stress. This was accomplished in many studies that included a comparison in the physiological and metabolic responses of warm-season and cool-season grass species to cold stress, with foliar application of naturally occurring cold responsive compounds, calcium dichloride, glycine betaine, abscisic acid, sucrose and potassium phosphate, and their effects on plant productivity and recovery from freezing stress. The collection of this information will help to expand our knowledge of cold acclimation and freezing tolerance in many grass species, and can be used for the development of more cold tolerance species or management practices to maintain plant health during low temperature or de-acclimation events.
