Chilling and Heat Requirements of Temperate Stone Fruit Trees (Prunus sp.)
Agronomy, 2020 Stone fruit trees of genus Prunus, like other temperate woody species, need to accumulate a cultivar-specific amount of chilling during endodormancy, and of heat during ecodormancy to flower properly in spring.

Frontiers in Plant Science, 2015 Many temperate and boreal tree species have a chilling requirement, that is, they need to experience cold temperatures during fall and winter to burst bud normally in the spring. Results from trials with 11 Pacific Northwest tree species are consistent

A hybrid dynamic modeling of active chilled beam terminal unit [PDF]
Applied Energy, 2014 Abstract This paper proposes a hybrid dynamic model of active chilled beam (ACB) terminal unit. The model encapsulates mechanical and thermal aspects of the confined air jet and the cooling coil contained in the terminal unit and could be divided into two sub-models respectively.

Effects of chill unit accumulation and temperature on woody plant deacclimation kinetics
Physiologia Plantarum, 2022 AbstractWoody perennials in temperate climates develop cold hardiness in the fall (acclimation) and lose cold hardiness in the spring (deacclimation) to survive freezing winter temperatures. Two main factors known to regulate deacclimation responses are dormancy status and temperature.

Genetic diversity in apple tree cultivars established in the Sierra de Arteaga, Coahuila, Mexico
Ecosistemas y Recursos Agropecuarios, 2018 Apple production in the Sierra de Arteaga, Coahuila is mainly based on the Golden Delicious cultivar. Production based on only a few cultivars represents a genetic risk, because if they are susceptible to a pest, disease or climate change much of this ...

Calculating Chilling Hours and Chill Units from Daily Maximum and Minimum Temperature Observations [PDF]
HortScience, 1990 Models that require hourly weather data as inputs are being constructed to simulate development of insects and plants. Most agricultural and, climatological weather observation stations, however, do not include the capability to record hourly data. Thus, methods, for simulating hourly observations need to be developed if the wealth of data collected in

Chilling units and chilling hours for southern region of Brazil and Aomori in Japan
Revista Eletrônica Científica da UERGS, 2018 The brazilian apple production are located in the southern region, with the best areas in altitudes ranging from 800 to 1400 m, with great variability in the number of Chilling Hours (CH) and Chilling Units (CU) in the different regions and years. The objective of this study was to compare CH equal or below 7.2°C and CU by the North Carolina Modified ...

Sugar units, not chilling units, control endodormancy duration in plants – potato tuber as a case study [PDF]
, 2021 SummaryEndodormancy (ED) is a crucial stage in the life cycle of many perennial plants, regulated by genetic and environmental factors. Chilling units, growth regulators, and nutrient supply are considered inducers of ED release, but the mechanism governing ED duration is poorly understood.

Determination of Chilling and Heat Requirement of Four Apricot Cultivars of Khorasan Razavi Province
Majallah-i ̒Ulum-i Bāghbānī, 2017 Introduction:Dormancy is one of the most important stages in the life cycle of temperate plants and plants are required to exit from it with supply of chill unit. Flowering is defined with chilling and heat requirement. Owing to low chilling requirement,
