Chilling and Forcing Requirements of Wintersweet (Chimonanthus praecox L.) Flowering in China
ForestsNumerous studies have reported phenological changes and their driving mechanisms in spring flowering plants. However, there is little research on the shifts of winter flowering phenology and its response to forcing and chilling requirements. Based on the

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.

Chilling requirements of Mediterranean fruit crops in a changing climate
Acta Horticulturae, 2019Fruit production in Europe may be hampered by climate change in terms of warmer winters resulting in insufficient chilling. This contribution provides a brief survey of winter chilling requirement of fruit crops. Therein, cherry and apple were identified

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.

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.
