| Abstract/Contents: | Extreme cold weather can massacre warm season turfgrasses which grow in many areas. Direct low-temperature kill occurs when ice crystals form within plant tissues as temps rapidly fall below 32 F. This kills the plant by disrupting the cellular structure. Extracellular freezing occurs when water is drawn out of plant cells as ice crystals form during freezing temperatures. Another problem with warm season perennial grasses is chilling injury. This occurs when temps fall below 50-and 57F. If temperatures decrease gradually during fall, turfgrasses can make physiological adjustments to enhance hardiness. This involves redistributing water within the plant and lowering cell water content. A number of factors effect the actual temps where death occurs. Turfgrasses are ranked according to low-temp hardiness. |
