Research advances in heat resistance of cool-season turfgrasses

Abstract

Abstract:

Cool-season turfgrasses are widely used on parks， sports fields and lawn in climate transition zones， due to their strong cold resistance， long green period and good ornamental effect. However， cool-season turfgrasses are sensitive to heat stress. High temperature in summer causes a series of physiological and metabolic disorders of turfgrasses， resulting in a decline in turf quality， increased occurrence of disease， dormancy， withering and even plant death， further affecting the performance of lawns or sports fields. This review describes the physiological and molecular mechanisms of high temperature stress tolerance in cool-season turfgrasses， especially with respect to carbon metabolism， antioxidant metabolism， hormone metabolism， heat-related genes and transcription factors. Current issues and future prospects pertaining to heat resistance mechanisms of cool-season turfgrasses are discussed， in order to provide a theoretical reference for use in further studies.

Key words: cool-season, turfgrass, heat resistance, physiological mechanisms, molecular mechanisms
