Chilling requirements of Paeonia cultivars
Scientia Horticulturae, 2001Abstract Dormant second year potted plants of Paeonia ‘Coral Sunset’, ‘Monsieur Jules Elie’, and ‘Sarah Bernhardt’ were placed into three chilling regimes (constant 1, 4, or 7°C) for different durations (3, 6, 9, or 12 weeks) to ascertain their chilling requirements for shoot and flower production. Chilling was followed by forcing for up to 5 weeks

The introduction of high chilling requirement genotypes can be useful to widen the genetic base of the low chilling requirement germplasm, mainly considering fruit quality. However, the hybrids among high and low chilling requirement genotypes can have poor adaptation in mild areas, with erratic budbreak and flowering.

Abstract Sweet cherry cultivars have different chilling and heat requirements for breaking rest and flowering. The knowledge of these requirements may be valuable in the selection of the appropriate cultivars for producers and to avoid losses caused by an inadequate cultivar selection in a particular area.

Climate Change and Chilling Requirements
2015Climate change has affected the rates of chilling and heat accumulation, which are vital for flowering and production, in temperate fruit trees (Guo et al. 2014). All economically important fruit and nut tree species that originated from temperate and cool subtropical regions have chilling requirements that need to be fulfilled each winter to ensure ...

The Chilling Requirement of Western Hemlock Seedlings
Forest Science, 1979Abstract Many tree species in temperate zones require a period of low temperatures to overcome dormancy. When seedlings of western hemlock were preconditioned with 6 wks of mild, short days, their chilling requirement was met by 4 wks of a constant 5°C temperature, considerably less chilling than required by Douglas-fir. Seedlings not

METHOD TO DETERMINE CHILLING REQUIREMENT IN BLUEBERRIES
Acta Horticulturae, 2006A chilling study was initiated in January 1998 on 'Tifblue' rabbiteye (Vaccinium ashei Reade) and blueberry plants that had received > 500 chilling hours (

INHERITANCE OF CHILLING REQUIREMENT IN PROGENIES OF APRICOT (PRUNUS ARMENIACA L.)
Acta Horticulturae, 2010This research had the aim to study, under the Mediterranean climatic conditions, the genetic variation of the Chilling Requirement (CR) character in progenies originated from parents with low-medium and very high CR. Adult apricot seedlings of seven year old, growing under the climatic conditions of the Tuscan coastal area, Italy (lat. 43,02N, long. 10,

Chilling requirements of the apple cultivar Stoke Red
Australian Journal of Experimental Agriculture and Animal Husbandry, 1974Trees of the apple cultivar Stoke Red were chilled at temperatures between 2°C and 10°C for periods up to 3000 hours. Extension growth and budbreak increased with increasing hours of chilling and decreasing temperatures. The cultivar was shown to require more chilling than is provided by southern Victorian winters.

Chilling and heat requirements for flowering in apricot cultivars
Acta Horticulturae, 2018Chilling requirements for breaking dormancy and heat requirements for flowering were studied in 10 apricot cultivars in the region of Belgrade during a 2‑year period. Chilling requirements were determined using the Utah chill unit (CU) model. To determine the date of dormancy breaking, 1-year-old shoots were collected weekly from December to February ...

Estimation of chilling and heat requirements for flowering in almond
Acta Horticulturae, 2020Assessment of chilling requirements for breaking dormancy (CR) and heat requirements for flowering (HR) in fruit trees is important for selecting cultivars suitable for the climatic conditions of the site. The objective of this study was to estimate CR and HR in six almond cultivars grown in the Belgrade region.
