Cold acclimation, deacclimation and memory in Arabidopsis [PDF]
, 2018 Plants from temperate regions can be cold acclimated by exposure to low, but non-freezing temperatures resulting in improved freezing tolerance. Whereas the molecular and metabolic basis of cold acclimation has been investigated in detail, little is known about the molecular regulation of deacclimation of cold acclimated plants under warm conditions ...

Deacclimation response to winter temperature fluctuations in Lolium perenne [PDF]
, 2018 Studies on climate change have shown an increase in not only the average global surface temperature but also an increase in extreme weather events. One such extreme weather event is the occurrence of winter temperature fluctuations, which can induce loss of cold acclimation.

Variations in Cold Resistance among Apple Cultivars during Deacclimation
Journal of Experimental Botany, 1985Coleman, W. K. 1985. Variations in cold resistance among apple cultivars during deacclimation.— J. exp. Bot. 36: 1159-1171. One-year-old vegetative twig samples from mature, bearing trees of nine apple cultivars were monitored over two years for their dormancy intensity and relative cold hardiness levels during the winter/spring deacclimation period ...

Enzyme changes during deacclimation of willow stem
Cryobiology, 1970Abstract Qualitative changes were found to occur for certain, but not all, enzymes studied during deacclimation in Salix cortex. Because of the possible involvement of esterases in lipid transformations during hardening and dehardening, changes in the isoesterase pattern were important.

Shivering and nonshivering thermogenesis in exercised cold-deacclimated rats
European Journal of Applied Physiology and Occupational Physiology, 1988Norepinephrine (NE)-induced increase in oxygen consumption (VO2) and colonic temperature (Tc) was greater in cold-acclimated rats housed at 4 degrees C for 4 weeks (CA) than warm-acclimated controls housed at 24 degrees C for 4 weeks (WA). On the other hand, shivering activity measured at 4 degrees C was less in CA than in WA, while propranolol ...

Acta Horticulturae, 2003
Blueberry cultivars with varying percentages of species ancestry (V. corymbosum L., V. angustifolium Ait., V. ashei Reade, V. darrowi Camp) were assayed in mid-February to determine initial bud hardiness, and rates of deacclimation under constant temperature conditions.

Effects of exercise detraining and deacclimation to the heat on plasma volume dynamics
European Journal of Applied Physiology and Occupational Physiology, 1986The effects of the discontinuation (DET) of an endurance training/heat acclimation (T/A) program on vascular volumes were studied in 16 adult males. Resting and exercise blood volume dynamics were examined prior to and during an exercise task performed after completion of T/A (CT1) and again at the end of DET (CT2).

Effect of Cold Deacclimation on Delayed Fluorescence of Spruce Needles
Zeitschrift für Pflanzenphysiologie, 1983Summary Delayed fluorescence of chlorophyll in the time range of 3–18 ms was studied in intact spruce needles. The temperature dependence of delayed fluorescence was measured during cold deacclimation and after artificial dehardening of the frostresistant P. abies and the frost-susceptible P. schrenkiana.

Winter survival and deacclimation of perennials under warming climate: physiological perspectives
Physiologia Plantarum, 2012Appropriate timing and rate of cold deacclimation and the ability to reacclimate are important components of winter survival of perennials in temperate and boreal zones. In association with the progressive increase in atmospheric CO2, temperate and boreal winters are becoming progressively milder, and temperature patterns are becoming irregular with ...
