Intraspecies differences in cold hardiness, carbohydrate content and β-amylase gene expression of Vaccinium corymbosum during cold acclimation and deacclimation.
Changes in cold hardiness, carbohydrate content and β-amylase gene expression were monitored in the shoots of the highbush blueberry (Vaccinium corymbosum L.) cultivars 'Sharpblue' and 'Jersey' during cold acclimation (CA) and deacclimation (DA). The seasonal patterns were similar in both cultivars, but the levels of cold hardiness determined by electrolyte leakage analysis were significantly d...
متن کاملTime-dependent deacclimation after cold acclimation in Arabidopsis thaliana accessions
During low temperature exposure, Arabidopsis thaliana and many other plants from temperate climates increase in freezing tolerance in a process termed cold acclimation. However, the correct timing and rate of deacclimation, resulting in loss of freezing tolerance and initiation of growth is equally important for plant fitness and survival. While the molecular basis of cold acclimation has been ...
متن کاملVariability in the Rate of Cold Acclimation and Deacclimation among Tuber-bearing Solanum (Potato) Species
Two major components of frost resistance are freezing tolerance in the nonacclimated state (growing in normal condition) and capacity to cold acclimate (increase in freezing tolerance upon exposure to chilling temperatures). In addition to these two major components, numerous factors contribute to frost survival. Although the rate of cold acclimation and deacclimation have been recognized as im...
متن کاملBud Hardiness and Deacclimation in Blueberry Cultivars With Varying Species Ancestry: Flowering Time May Not Be a Good Indicator of Deacclimation
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. The LT50 (the temperature at which 50% lethality occurs) of detached shoots of field-grown plants of ‘Weymouth’, ‘Bluecrop’, ‘...
