; Weiser, 1970 ) and is recognized to occur in many freeze-tolerant temperate woody plants ( Li et al., 2003 ; Welling et al., 2002 , 2004 ; Wisniewski et al., 2003 ). Woody plants evolved two freezing responses for surviving prolonged exposure to

Freezing temperatures are one of the major constraints for palm cultivation in temperate regions. Severe cold damage can destroy plant tissues and may severely reduce water conduction in the stem ( Larcher and Winter, 1981 ; Meerow, 2005 ). When

that plays an important role in plant cold acclimation by facilitating plant acquire freezing tolerance. At a genomic level, it has been found that three unique C-repeat/DRE Binding Factor genes were upregulated by low-temperature treatment or exogenous

has been considered the primary site of freezing injury in plants ( Arora and Palta, 1991 ; Levitt, 1980 ; Steponkus, 1984 ). Freeze-induced damages of the membrane are primarily the result of severe cellular dehydration associated with freezing

Plant resistance to freezing stress includes avoidance, evasion, and tolerance strategies ( Levitt, 1980 ). Many annual plants complete the vegetative phase of the life cycle when freezing temperatures do not normally occur, effectively evading the

States, there is an increased public interest in using turf species that can tolerate reduced irrigation and saline soil. Freezing is the major environmental stress that limits geographic distribution of warm season turfgrass species. Variation in

In areas with a Mediterranean climate, frost can occur in the field in winter or early spring. The production of ornamental plants in the nursery may be affected by freezing temperatures, which can produce severe injuries in the plants. Although
