Budbreak of Rabbiteye Blueberry Enhanced by Hydrogen Cyanamide
HortScience, 1998 Few flower buds on pot grown `T-227' rabbiteye blueberry (Vaccinium ashei Reade) advanced past stage 1 (tight bud) when exposed to 0 or 200 h of chilling temperatures (4 °C), regardless of treatment with hydrogen cyanamide. However, 0.25%, 0.5%, 1%, and 2% sprays on plants chilled 400 h advanced flower bud development through stage 6 (open).

Refrigeration of the Root Zone to Delay Budbreak in Grapes [PDF]
HortScience, 2000 Grapes grown in West Texas are especially susceptible to freeze damage during spring deacclimation and budbreak. This experiment was undertaken to evaluate whether refrigeration of the root zone would delay budbreak in two grape cultivars, `Chardonnay' and `Cabernet Sauvignon'.

HortScience, 1987 Abstract Interest in artificial control of budbreak of deciduous fruit trees species is closely connected with commercial attempts to grow these species in warm locations, where the chilling requirements are not fulfilled naturally. This interest developed following attempts to grow such species in warm countries that did not want to or could not ...

Results of a phenological study at a young Norway spruce (Picea abies/L./Karst)
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2010 The paper deals with results of phenological studies of Norway spruce (Picea abies/L./ Karst.) in a mixed stand. This broad range was important in spring phenological stages.

Increasing Chilling Reduces Heat Requirement for Floral Budbreak in Peach [PDF]
HortScience, 2011 Response to chilling temperatures is a critical factor in the suitability of peach [Prunus persica (L.) Batsch] cultivars to moderate climates such as in the southeastern United States. Time of bloom depends on the innate chilling requirement of the cultivar as well as the timing and duration of cold and warm temperatures experienced by the buds.

Biological methods for assessment of budbreak in apple trees for modeling dormancy
Semina: Ciências Agrárias, 2014 A biological method was developed to evaluate the dormancy state of apple buds under controlled conditions. Cuttings (20-25 cm long) of ‘Castel Gala’ and ‘Royal Gala’ were sampled during the winter period, evaluating different cold and heat regimes to ...

HorticulturaeClimate 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.

Plant, Cell &Environment, EarlyView.ABSTRACT Irradiance strongly affects the morphology, carbon (C) uptake and construction costs of leaves and branches. Within tree crowns, light decreases from the top downwards, but whether this translates to differences in the C balance of sun and shade branches remains unclear. Here, we combined a light‐driven photosynthesis model, parameterised with

Reduced snow cover at the alpine treeline: resistance and recovery of saplings
New Phytologist, Volume 250, Issue 3, Page 1492-1509, May 2026.Summary At high elevations, tree saplings and shrubs are usually protected by mid‐winter snow cover, although climate change is expected to extend the snow‐free (SF) period. Exposure to winter drought, freeze–thaw events and freezing temperatures will therefore increase, inducing damages to the hydraulic system and to living cells, resulting in reduced
