Chilling requirements of Paeonia cultivars

Scientia Horticulturae, 2001
Abstract 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

CHILLING REQUIREMENT EVALUATION OF PEACH HYBRIDS OBTAINED AMONG CULTIVARS WITH HIGH AND LOW CHILLING REQUIREMENTS

Acta Horticulturae, 2010
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 and heat requirements of sweet cherry cultivars and the relationship between altitude and the probability of satisfying the chill requirements

Environmental and Experimental Botany, 2008
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

2015
Climate 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, 1979
Abstract 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, 2006
A chilling study was initiated in January 1998 on 'Tifblue' rabbiteye (Vaccinium ashei Reade) and blueberry plants that had received > 500 chilling hours (
