Chill unit accumulation and necessity of rest breaking agents in South African table grape production regions

open access: yesBIO Web of Conferences, 2014
Cultivation of table grapes in warm regions of South Africa is complicated by problems associated with delayed and uneven bud break. Rest breaking agents, mainly hydrogen cyanamide, are applied to overcome these problems.

The Influence of Bud Positions on the Changes in Carbohydrates and Nitrogen in Response to Hydrogen Cyanamide During Budbreak in Low-Chill Kiwifruit

open access: yesHorticulturae
Climate change has contributed to a decline in winter chilling accumulation, a critical requirement for budbreak in temperate fruit crops. Its consequence has been a reduction in fruit production.

Chilling Requirement of Pecan [PDF]

open access: yesJournal of the American Society for Horticultural Science, 1992
`Dodd' pecan seedlings [Carya illinoinensis (Wangenh.) K. Koch] were chilled at 6C for 0 to 1800 hours in 300-hour intervals and percent budbreak and days to budbreak recorded. Chilling duration required for ≥ 50% budbreak was 900 hours.

Estimating heat requirement for floral bud break in peach germplasm

open access: yes, 2022
In this article, heat requirement diversity in a large set of U.S. peach germplasm was presented with a goal to determine the best approach for estimating this trait and if observed diversity could be used in breeding to counter climate change.

POLLEN DEVELOPMENT AND CHILLING REQUIREMENTS IN APRICOT CULTIVARS [PDF]

open access: yesActa Horticulturae, 2009
Apricot (Prunus armeniaca L.) flowers at the end of the winter but flower bud differentiation occurs the previous summer. During the winter, the flower bud enters dormancy and resumes growth prior to flowering. The time the flower bud remains dormant is genetically and also environmentally controlled and is a major factor in determining the adaptation ...

CHILLING REQUIREMENTS OF HAZELNUT CULTIVARS [PDF]

open access: yesHortScience, 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 ...

Identification and Characterization of DAMs Mutations Associated With Early Blooming in Sweet Cherry, and Validation of DNA-Based Markers for Selection

open access: yesFrontiers in Plant Science, 2021
Dormancy release and bloom time of sweet cherry cultivars depend on the environment and the genotype. The knowledge of these traits is essential for cultivar adaptation to different growing areas, and to ensure fruit set in the current climate change ...

Defining the QTL for chill requirement during dormancy and dormancy release in apple (Malus x domestica Borkh.). [PDF]

open access: yes, 2021
Thesis (PhDAgric)--Stellenbosch University, 2021.ENGLISH ABSTRACT: Dormancy is a physiological stage that all deciduous fruit trees experience during winter. It consists of three sub stages, para-, endo- and ecodormancy.

Impact of Climate Change on Winter Chilling Trend for Deciduous Fruit Trees (Case Study: Hamadan)

open access: yesMajallah-i ̒Ulum-i Bāghbānī, 2016
Introduction :Higher temperature as the result of climate change are likely to affect horticultural production. Deciduous fruit trees need winter chilling to break winter dormancy. Climate plays an important role in the successful production of deciduous

Distinctive Gene Expression Patterns Define Endodormancy to Ecodormancy Transition in Apricot and Peach

open access: yesFrontiers in Plant Science, 2020
Dormancy is a physiological state that plants enter for winter hardiness. Environmental-induced dormancy onset and release in temperate perennials coordinate growth cessation and resumption, but how the entire process, especially chilling-dependent ...
