undergo cold acclimation in late fall as temperature drop and photoperiod gets shorter. It has been well documented that increased cold acclimation could improve freeze tolerance of plants, including turfgrasses ( Anderson et al., 2003 ). Plants possess

. For example, Rogers et al. (1975) reported accumulation of total nonstructural carbohydrate and starch during cold acclimation in ‘Meyer’ in a field study. In contrast, Patton et al. (2007a) reported decreased starch concentrations in zoysiagrass

excellent cold resistance and could tolerate temperatures as low as −35 °C ( Gusta et al., 1980 ). However, creeping bentgrass has suffered winter-kill in some temperate regions such as in northern China. Winter-kill is a general term that is used to define

requirements for prior exposure to cold temperature (chilling) have been satisfied, i.e., vernalization and/or breaking of endodormancy ( Iversen and Weiler, 1994 ). Inadequate accumulation of chill units can result in delayed or uneven shoot emergence, reduced

Plants endure many biotic and abiotic stresses, including exposure to cold temperatures. Tremendous damage to plant cells can result from freezing temperatures, primarily to the cellular membranes ( Thomashow, 1999 ). Many plants have adapted to

as a commercial ornamental plant in North America is limited, principally because of a lack of cold hardiness. Almost all of Australia corresponds to the U.S. Department of Agriculture (USDA) hardiness zone 9 or higher ( Dawson, 1991 ), and as a

The relationship between fertilization and cold tolerance of plants is a confusing one. Plant nutrition involves a number of different elements, each of which may affect a plant's cold tolerance in a different manner. Most studies on fertility

temperature can influence growth, development, and yield of botanical species ( Zhu et al., 2007 ). Hughes and Dunn (1996) reported that when exposed to low but not freezing temperature, plants can obtain chilling and freezing tolerance (cold acclimation
