Godley review: A touch of frost? Cold hardiness of plants in the southern hemisphere

This review contrasts the frost resistance of plants from the Southern Hemisphere with that of the Northern Hemisphere and is principally concerned with plants from New Zealand, Australia, and South America. It gives a brief overview of methods for determining frost resistance in the field and in controlled environments with intact or excised plant parts. It considers various methods of determining frost resistance and the expression of critical temperatures causing damage, and discusses the problems of using excised plant parts and freezing of tissues. This review, however, is not principally concerned with physiological aspects of frost resistance, but more with biogeographic aspects of the environment and quantification of the relationships between frost resistance and temperature related factors such as altitude and latitude. It gives examples of differences in frost resistance between the two hemispheres and attributes these to the contrast between the climates of largely continental land masses in the Northern Hemisphere and the oceanic environment of the Southern Hemisphere. Furthermore, it also shows similarities between the frost resistance of plants from the Southern Hemisphere during the growing season and the maximum frost resistance of tropical alpine species and further similarities between species on oceanic islands in both hemispheres. Comprehensive lists of species' frost resistance are included in tables and appendices.

“…Research has shown that polar lipids change when plants are exposed to stress such as drought, oxidative assaults, or extreme temperatures (Chen et al, 2006;Li et al, 2004;Selstam and Ö ouist, 1990;Styer et al, 1996;Toivonen et al, 1992;Wang, 2005). Higher concentrations of polar lipids were observed in woody evergreen leaves (Nothofagus dombeyi) from plants grown at high altitudes (LT 50 = -10.2°C) compared with those grown at lower altitudes (LT 50 = -5.0°C) (Alberdi et al, 1990). Furthermore, dominant lipids in N. dombeyi, digalactosyl diacylglycerol (DGDG), monogalactosyl diacylglycerol (MGDG), and phosphatidylglycerol (PG), increased 200% to 400% during cold acclimation.…”

Cell membranes play an integral role in freezing tolerance. The objectives of this study were to quantify polar lipids in cold-tolerant ‘Meyer’ zoysiagrass (Zoysia japonica) and cold-sensitive ‘Cavalier’ zoysiagrass (Zoysia matrella) and to evaluate their potential role in freezing tolerance. Grasses were acclimated outside and sampled once monthly between October and January to determine freezing tolerance and lipid composition in rhizomes. Lowest LT50s (temperature resulting in 50% survival) were observed in November for ‘Cavalier’ (−8.5 and −9.6 °C in 2005 and 2006, respectively) and December for ‘Meyer’ (−16.2 and −15.4 °C in 2005 and 2006, respectively). The most abundant lipids in zoysiagrass rhizomes were monogalactosyl diacylglycerol, digalactosyl diacylglycerol, phosphatidylcholine, phosphatidylethanolamine, and phosphatidic acid, which comprised 90% of the polar lipids. Differences in lipid contents and double bond indices (DBI) were detected between ‘Meyer’ and ‘Cavalier’ during cold acclimation, but there were no consistent relationships between lipid classes or DBI and freezing tolerance in zoysiagrass.
