Dormancy in Grapevine Cultivars Across Various Pruning Treatments in the Mediterranean Region of Israel

Australian Journal of Grape and Wine Research, Volume 2026, Issue 1, 2026.
Background and Aims Dormancy in grapevines (Vitis vinifera) is a critical adaptive strategy that enables vines to survive harsh winter conditions and is influenced by physiological and environmental factors. This study aimed to investigate the progression of endodormancy across different pruning dates and cultivars and to identify the key ...

Predicting Key Grapevine Phenological Stages in Eastern Canada: Insights From 15 Years of Field Observational Data

Australian Journal of Grape and Wine Research, Volume 2026, Issue 1, 2026.
The study aimed to develop predictive models for key grapevine phenological stages in northern climates using 15 years of field observations. The research focused on major cultivars grown in eastern Canada (Frontenac, Marquette, Seyval, and Vidal), where viticulture is expanding.

Evaluation of winter temperatures on apple budbreak using grafted twigs

Revista Brasileira de Fruticultura, 2013
Temperature is the main climate factor related to induction, maintenance and dormancy release in apple (Malus domestica Borkh.). The inadequate chilling exposure in apples causes budbreak problems, resulting in decrease in yield potential.

Performance of ‘Maxi Gala’ apple trees as affected by budbreak promoters, in São Joaquim-SC

Revista Brasileira de Fruticultura, 2018
The application of rest breaking agents to compensate the lack of chilling is a common practice in apple orchards in Southern Brazil. However, its necessity in areas of greater chilling accumulation has been questioned over the years.

Heat requeriment for inducing budbreaking in different apple cultivars

, 2021
The heat requirements for bud burst of six apple cultivars were evaluated. Shoots with 20 to 25cmlength were submitted to 1,150 cold units. After this treatment, shoots were divided in single bud cuttings and treated at different temperatures (5, 10, 15, 20 and 25oC).

Chilling and Budbreak in Lingonberries, Vaccinium vitis-idaea L.1

Journal of the American Society for Horticultural Science, 1983
Abstract Three seedling populations of lingonberries from Fairbanks, Alaska, Oulu, Finland, and the Pasvik River Valley, Norway were exposed to 0, 170, 344, 513, 681, 843, 1013, and 1185 hours of continuous chilling temperatures (4 ± 1°C) to determine chilling requirements necessary to satisfy rest.
