The Analysis of Cold Hardiness Experiments

2001
Scientific studies generally belong to one of three categories: designed experiments, sample surveys, and observational studies. Most research on the cold hardiness of conifers is based on designed experiments where the scientist wishes to compare two or more treatments.

Principles of Insect Cold-Hardiness

Annual Review of Entomology, 1961
Cold is a relative term which for present purposes will be considered to encompass temperatures too low to support normal development of the in­ sects concerned. The effects of cold on insects may be manifold, but a pri­ mary distinction must be made on the hasis of whether freezing does or does not result.

Cold Hardiness of Saltgrass Accessions

Crop Science, 2003
Freezing tolerance is an environmental adaptation that significantly influences plant geographical distribution. Since differences in winter survival among saltgrass ecotypes have been observed in the field at Fort Collins, CO, the objective of this study was to determine the relative freezing tolerance, seasonal changes in the freezing tolerance, and ...

Mutants Deficient in Cold Hardiness

2002
Mutations that affect cold hardiness, if their effects are specific, identify proteins that help to protect plant cells against chilling or freezing. This offers an approach to cold hardiness complementary to the study of low temperature-induced genes and the cold signal transduction pathway. The approaches have different limitations.

Presoaking and cold hardiness in maize

Plant and Soil, 1949
Seed of four inbred sweet corns and one dent hybrid corn were presoaked in tap water prior to receiving 60°F and 40°F treatment. Pre-soaking did not alter their behaviour to cold treatment, although on transference to the warmth, germination was slightly more rapid after pre-soaking.

Comparative Invertebrate Cold Hardiness

1991
Insects are the most thoroughly studied freeze-tolerant organisms. There are, however, several other groups of animals that can survive the presence of ice in their extracellular fluids. These include some lower vertebrates, such as frogs, turtles, and snakes and intertidal invertebrates.

Cold Hardiness in Terrestrial Arthropods

1995
During the last few decades a vast number of articles have been published within the field of cold hardiness in insects and other terrestrial arthropods. The intriguing question as to how poikilotherm animals are able to survive temperatures far below the melting points of their haemolymph has puzzled many biologists.
