Deacclimation may be crucial for winter survival of cereals under warming climate
Plant Science, 2017Climate warming can change the winter weather patterns. Warmer temperatures during winter result in a lower risk of extreme freezing events. On the other hand the predicted warm gaps during winter will decrease their freezing tolerance. Both contradict effects will affect winter survival but their resultant effect is unclear.

Cold Acclimation and Deacclimation of Shoots and Roots of Conifer Seedlings
2001Conifers that are adapted to grow in regions where marked annual temperature changes are observed have developed physiological mechanisms that enable them to alternate their growth and rest periods in phase with the climate, so they exhibit a strong periodicity in cold hardiness. Cold acclimation is the transition from a non-hardy state to a hardy one.

Examination of Cold Deacclimation Sensitivity of Annual Bluegrass and Creeping Bentgrass
Crop Science, 2014ABSTRACTAnnual bluegrass (Poa annua L.) (AB) frequently exhibits increased susceptibility to winter injury compared to other cool‐season turfgrass species such as creeping bentgrass (Agrostis stolonifera L.) (CB). Interspecific differences in winter survival of these two species may be associated with enhanced sensitivity of AB to decreases in freezing

Memory of long-term cold acclimation in deacclimated Wistar rats
Journal of Thermal Biology, 2006Abstract Long-term cold exposure (10 °C for 11weeks) led to hyperplasia of brown adipose tissue (BAT) in rats. After deacclimation (25 °C for 2 weeks, after 10 °C for 9 weeks), BAT retained almost the same mass as in cold acclimation, and lipid content and droplet size decreased slightly, although the droplets fused with each other.

Ethylene and ethane evolution during cold acclimation and deacclimation of ponderosa pine
Canadian Journal of Forest Research, 1991Greenhouse container-grown ponderosa pine (Pinusponderosa var. scopulorum Engelm.) were cold acclimated and deacclimated in growth chambers during a 19-week regime. Seedling cold hardiness, bud dormancy, and ethylene and ethane evolution from excised needles were measured weekly.

Deacclimation and reacclimation of cold-hardy plants: Current understanding and emerging concepts
Plant Science, 2006The abilities of cold-hardy plants to resist deacclimation during transient warm spells and to reacclimate when cold temperatures return are significant for winter survival. Yet compared to the volume of research on the biology of cold acclimation, relatively little is known about how plants maintain and/or reacquire cold hardiness in late winter and ...

Physiologia Plantarum, 2014
Cold acclimated plants show an elevated tolerance against subsequent cold stress. Such adaptation requires alterations in gene expression as well as physiological changes. We were interested in gene expression changes at the transcriptional level during adaptation processes.

Timing of deacclimation affects the ability to recover from simulated winter herbivory
Plant Ecology, 1998The ability of Vaccinium myrtillus L. to recover from simulated winter herbivory has been investigated on different plants which had been exposed to three elevated temperatures (5 °C, 10 °C or 20 °C) for four weeks in a greenhouse environment. After herbivory, number and length of new aerial shoots and number of leaves/shoot increased faster in plants ...

The formation and distribution of ice within dormant and deacclimated peach flower buds
Plant, Cell & Environment, 1989Abstract A freeze‐fixation technique was used to examine the distribution of ice crystals and the pattern of freezing in peach flower buds. In dormant buds, ice crystals formed at localized sites within the bud axis and scales. Ice crystal formation disrupted tissues and mechanical injury from repetitive freezethaw cycles was apparent.
