Genetic studies of frost resistance in wheat

Theoretical and Applied Genetics, 1981
Genetic studies of frost resistance were performed on various wheat varieties using diallel, F2 monosomic and substitution analysis.A six-parental cross including reciprocals was carried out, and F1 hybrids and their parents were used for the freezing tests under controlled conditions. Both the general combining ability (GCA) and the specific combining

Frost resistance of rock materials

Construction and Building Materials, 2017
Abstract A precise classification of rock raw materials with respect to frost-resistance is still an issue. The knowledge of the rock’s origin and its mineral composition and structure is not an effective diagnostic tool. This paper discusses the possibility of applying the capillary absorption and volumetric strain of a frozen rock sample for ...

Frost resistance in adult insects

Journal of Insect Physiology, 1972
Abstract Some adult Coleoptera and Hymenoptera collected in winter in Hokkaido, Japan, proved to be frost-resistant. The limit of low temperatures at which they could tolerate prolonged freezing without any post-thawing injury was only −10°C regardless of their glycerol content.

Frost Resistance of Silicate Bricks

Stroitel'nye Materialy
The article presents the results of a research frost resistance of silicate bricks one of the Russian factories produced in different periods. The change in appearance, weight and strength of silicate bricks during alternate freezing-thawing was evaluated.

Frost Resistance and the Distribution of Conifers

2001
The distribution of plants is well correlated with climate. For example, Koppen’s (1936) climate classification is based on major biomes which are subdivided with respect to various relationships between temperature and precipitation, whilst Thornthwaite’s (1948) classification is based on potential evapo-transpiration.

Frost, Drought, and Heat Resistance

Annual Review of Plant Physiology, 1951
With the exception of Chapter 5, the present work deals solely with plants. This was necessary because the author is a botanist and not familiar with the animal literature. It is also reasonable, since tolerance plays a greater role in the resistance of plants. The greater complexity of animal morphology, which may lead to the death of a whole organism
