ZusammenfassungUm die Auswirkungen des Klimawandels auf den deutschen Obstbau zu quantifizieren, befasst sich diese Arbeit mit langzeitlichen Trends in der Verfügbarkeit von Kältewirkung (Chilling) für Obstgehölze. Die Berechnungen erfolgten nach dem Kältestunden-Modell und dem Kälteportionen-Modell (Dynamisches Modell).Aus täglichen Aufzeichnungen von 43 Wetterstationen wurden mittels idealisierter täglicher Temperaturkurven stündliche Temperaturen während des 20. und späten 19. Jahrhunderts… Expand

Future Bloom and Blossom Frost Risk for Malus domestica Considering Climate Model and Impact Model Uncertainties
TLDR
Blossom frost risk cannot be stated to be lower by the end of the 21st century despite a negative trend, and is however unlikely to increase, while phenological model performance was improved by considering the length of day. Expand
Identification of chilling and heat requirements of cherry trees—a statistical approach
TLDR
Closer investigation of the distinct chilling phases detected by PLS regression could contribute to the understanding of dormancy processes and thus help fruit and nut growers identify suitable tree cultivars for a future in which static climatic conditions can no longer be assumed. Expand
A global analysis of the comparability of winter chill models for fruit and nut trees
TLDR
Safe Winter Chill was calculated for 5,078 weather stations around the world, using the Dynamic Model [in Chill Portions (CP), the Chilling Hours (CH) Model and the Utah Model [Utah Chill Units (UCU), and Distributions of the ratios between different winter chill metrics were mapped on a global scale.

Impact of chilling requirements on metabolic changes in nitrogenous compounds in buds during and after dormancy releasing in early and late (Malus sylvestris, Mill) apple varieties
Because of the winter in Egypt is short and does not meet the chilling requirements of buds, the delay in opening the buds of lateopining apple trees until late winter exposes them to damage underExpand
Climate Change Affects Winter Chill for Temperate Fruit and Nut Trees
TLDR
To better prepare for likely impacts of climate change, efforts should be undertaken to breed tree cultivars for lower chilling requirements, to develop tools to cope with insufficient winter chill, and to better understand the temperature responses of tree crops. Expand
Prospects of decreasing winter chill for deciduous fruit production in Chile throughout the 21st century
In Mediterranean climates, many deciduous fruit trees are unable to meet their seasonal chill requirements, a situation that may be exacerbated by global warming. Modeling approaches can be used toExpand

Climatic Changes Lead to Declining Winter Chill for Fruit and Nut Trees in California during 1950–2099
TLDR
Both chilling models consistently projected climatic conditions by the middle to end of the 21st century that will no longer support some of the main tree crops currently grown in California, with the Chilling Hours Model projecting greater changes than the Dynamic Model. Expand
Models of the spring phenology of boreal and temperate trees: Is there something missing?
TLDR
It is concluded that besides chilling, other environmental factors are involved in the regulation of the timing of bud burst, and further work is needed to determine if the regulatory factors derive from air temperature or from some other environmental condition such as changes in light conditions.

Fruit production systems that rely on winter chill for breaking of dormancy might be vulnerable to climatic change. We investigated decreases in the number of winter chilling hours (0–7.2°C) in fourExpand
Climatic determinants of budburst seasonality in four temperate‐zone tree species
TLDR
Although summer temperatures may be well involved in the intensity of dormancy and cold hardiness, they do not significantly aect budburst and therefore may not need to be considered in phenological models for predicting budburst. Expand
