CHILLING AND HEAT REQUIREMENT IN APRICOT AND PEACH VARIETIES

Acta Horticulturae, 2004
The aim of this research was to characterise the phenological behaviour of five peach and five apricot cultivars and to quantify their chilling and heat requirements by evaluating and comparing the applicability of different temperature models in Northwest Italy.

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.

Predicting chill accumulation requirements using different models

2002
Chill accumulation models are used to estimate the days from the end of a season until bud break in the following season. Trees have specific chill requirements that are related to the number of accumulated hours within a known temperature range. A new chill accumulation model was developed to improve the estimation of bud break date. In this model, we

Chilling requirements of the apple cultivar Stoke Red

Australian Journal of Experimental Agriculture and Animal Husbandry, 1974
Trees 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 requirement of commercialEchinaceaseed

New Zealand Journal of Crop and Horticultural Science, 1996
Abstract This study aimed to determine the effect of the moist chilling of seed on germination of Echinacea angustifolia DC. and Echinacea purpurea (L.) Moench, and the effect of seed coat trimming on the germination of E. angustifolia. Seed of E. angustifolia stratified for more than 2 weeks achieved maximum germination rates of 65–80%.

Phenological olive chilling requirements in Umbria (Italy) and Andalusia (Spain)

Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology, 2004
Phenological observations in olive tree (Olea europaea L.), on the first reproductive phase (budburst) and the winter chilling temperatures required for its onset, were analysed over a 4-year period (1998 - 2001). Research was carried out on two different cultivars growing in two Mediterranean olive-growing areas: 'Ascolana' in central Italy and ...

CHILLING REQUIREMENT OF STRAWBERRY CV. 'SONATA' AND 'FIGARO'

Acta Horticulturae, 2009
'Sonata' and 'Figaro' are two new Junebearers from the breeding programme of Fresh Forward, The Netherlands. Runner plantlets of both cultivars were transplanted in trays outdoors on 15 July 2006. On 23 November 2006, after receiving 436 chill units in the field, the trayplants were put into cold storage at -1.5°C.

INHERITANCE OF CHILLING REQUIREMENT IN PROGENIES OF APRICOT (PRUNUS ARMENIACA L.)

Acta Horticulturae, 2010
This 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,

Phenology of Apple Cultivars with Different Chilling Requirements

Journal of Experimental Agriculture International
Under mild climate conditions where chilling requirements are not met, the different phenological stages tend to extend and vary according to the year and chilling intensity. Knowledge on the phenological stages becomes important for the management of some cultural practices such as fruit thinning and phytosanitary treatments. The phenology of ‘Condesa’
