CHILLING REQUIREMENTS OF HAZELNUT CULTIVARS [PDF]

open access: bronzeHortScience, 1990
Chilling requirements of 44 genotypes of Corylus avellana L. were estimated by cutting shoots in the field at weekly intervals and forcing them in a warm greenhouse for four weeks. The chilling requirements of catkins, female flowers, and leaf buds were assumed to have been met when development occurred on more than half of the respective plant parts ...

R-based workflow to estimate chilling requirements in multiple fruit tree genotypes using Partial Least Squares regression: Prunus armeniaca L. case [PDF]

open access: yesMethodsX
Accurate estimation of chilling requirements (CR) is essential for breeding and selecting temperate fruit trees adapted to specific agroclimatic conditions, particularly under global warming scenarios.

Perspectives on the adaptation of Japanese plum-type cultivars to reduced winter chilling in two regions of Spain [PDF]

open access: yesFrontiers in Plant Science
Japanese plum, like other temperate fruit tree species, has cultivar-specific temperature requirements during dormancy for proper flowering. Knowing the temperature requirements of this species is of increasing interest due to the great genetic ...

Predicted global warming and Douglas-fir chilling requirements [PDF]

open access: greenAnnales des Sciences Forestières, 1990
Potted Douglas-fir [Pseudotsuga menziesii (Mirb) Franco)] seedlings from warm coastal and cool mountainous Oregon seed sources, grown under natural conditions, were chilled at constant temperatures of 5, 7, or 9 °C for periods of 9, 11, 13, or 15 wk beginning in mid-October.

Relationship between Chilling Accumulation and Heat Requirement for Flowering in Peach Varieties of Different Chilling Requirements

open access: yesAgronomy
Previous studies have shown a negative correlation between chilling accumulation (CA) and heat requirements (HRs) in peaches (Prunus persica (L.) Batsch), consistent with findings in other plants in spring events.

Spatial Distribution of the Probability of Satisfying the Chill Requirements of Pistachio in Iran Using ERA5-Land Reanalysis Data [PDF]

open access: yesNīvār, 2023
The pistachio nut is native to Iran and this country has the most favorable climate for cultivating pistachio trees. Generally, there were only five main pistachio producing-provinces in Iran including Kerman, Khorasan, Yazd, and Semnan.

Chilling requirements and flower bud development in cherry [PDF]

open access: yes, 2013
1 Pag. extracted from the Abstracts Book of the International Symposium. The work was performed along two consecutive years, paying attention to the possible anatomical and cytochemical changes accompanying dormancy. Results show that while no anatomical variations occur along dormancy, conspicuous cytochemical changes can be tracked ...

Chilling Requirement Studies in Blueberries [PDF]

open access: yesSmall Fruits Review, 2004
SUMMARY Two separate studies were initiated in January 1998 on Tifblue' rabbiteye (Vaccinium ashei Reade) and ‘Magnolia’ southern highbush (V. corymbosum L.) blueberry plants that had received > 500 chilling hours (7°C). In each study, the terminal 2 flower buds from both excised stems and paired stems on plants were forced in a greenhouse (17-23°C and

Agroclimatic Requirements of Traditional European Pear (Pyrus communis L.) Cultivars from Australia, Europe, and North America

open access: yesAgronomy, 2023
Flowering in temperate fruit trees depends on the temperatures during the previous months; chill is required to overcome endodormancy, and then heat exposure is needed.

Chilling requirement of Ribes cultivars [PDF]

open access: yesFrontiers in Plant Science, 2015
It is usually thought that adequate winter chill is required for the full flowering of many temperate woody species. This paper investigates the sensitivity of blackcurrant bud burst and flowering to natural weather fluctuations in a temperate maritime climate, and compares a range of chill models that have been proposed for assessing the accumulation ...
