Winter hardiness is influenced by many environmental factors, and freezing tolerance among the main ones, rendering phenotypic selection of winter wheat (Triticum aestivum L.) under field conditions a difficult task due to irregular occurrence or absence damage in trials. Plant growth response low temperatures during acclimation period might be used as an indirect approach assess tolerance. Thi...

The serum of winter flounder contains a group of antifreeze peptides which lower the freezing point of their body fluid in the winter. These antifreeze peptides disappear from their serum in the summer when the water temperature rises. Messenger RNA isolated from the liver of flounder collected in January directs the synthesis of predominantly one protein in an in vitro protein synthesis system...

Abstract The article deals with the problem of concrete durability in area variable water level port facilities. Particular attention was paid to exposure both negative temperatures and sea water. reasons for destruction first winter season under prolonged freezing structures ice were analyzed. authors come conclusion that alternating thawing is not always a major critical value severity frost ...

Diving seabirds that overwinter at high latitudes experience persistent cold exposure, short days and associated declines in ocean productivity that can challenge their ability to balance daily energy budgets. We used dive-immersion geo-locators to test the hypothesis that pursuit-diving Commonmurres (Uria aalge) will respond to the challenges of winter in the North Atlantic through increased d...

Riparian zones support some of the most dynamic and species-rich plant communities in cold regions. A common conception among plant ecologists is that flooding during the season when plants are dormant generally has little effect on the survival and production of riparian vegetation. We show that winter floods may also be of fundamental importance for the composition of riverine vegetation. We ...

In high-latitude regions, the cold hardiness of buds and canes grapevine is important for budburst time yield in next season. The freezing resistance sampled from six wine grapes currently cultivated Hokkaido, Japan, all them grown autumn to winter, was investigated. A significant difference between cultivars their detected harvested winter. addition, outstanding differences lower temperature e...

Kashmir is located in a region where winter temperatures are very low. During the winter months, the temperature in Kashmir is often below 0⁰ C. Generally concrete placed in colder regions with the help of insulated forms as well as heaters to protect freshly mixed concrete against freezing. These practices try to incorporate unnecessary carbon and leads to an disagreeable carbon footprint. The...

Winter frost resistance (WFR), midwinter frost hardening and frost dehardening potential of Pinus cembra L. were determined in situ by means of a novel low-temperature freezing system at the alpine timberline ecotone (1950 m a.s.l., Mt Patscherkofel, Innsbruck, Austria). In situ liquid nitrogen (LN₂)-quenching experiments should check whether maximum WFR of P. cembra belonging to the frost hard...

Interest in the preservation of endangered breeds such as the Blanca Andaluza goat, has increased and some steps should be therefore taken to ensure it. The study was designed to determine the seasonal reproductive pattern of Blanca Andaluza bucks, and whether this affects the quality of their semen and its freezability over the year. Seven bucks were used and their body weight, testicular weig...

The research was carried out in order to assess the winter hardiness of apple varieties Oryol and Michurinsky selection, as well elite hybrids selection Scientific Research Institute Horticulture Medicinal Plants Zhigulevskie Sady conditions continental climate characteristic Samara region. Freezing annual branches taken from trees 1011 years age laboratory under controlled a freezer at extreme...
