Using Self-Organizing Maps to Calculate Chilling Hours as an Indicator of Temperature Shifts During Winter in the Southeastern United States
… measure of dormancy time in plants, chill hours present a measurement capable of tracking phenological shifts in plants. While a lack of required chill hours can delay spring emergence, intense warm periods can override the chilling hour requirement and induce spring emergence. This project …

Accessing Chilling Conditions For Perennial Fruit Crop Production in Kentucky
… plants, require cool winter temperatures (chilling hours) to ensure leaf and flower bud production in the following season. Temperate Regions are characterized by variable winter and spring temperatures. Failure of meeting sufficient chilling requirement results in deformed fruits, unequal …

ASSESSING FREEZING EFFECT ON KIWIFRUIT CULTIVARS AND MAPPING SUITABLE AREAS FOR GROWING THE CROP IN EASTERN TEXAS
… require low to moderate soil pH, adequate winter chilling and adequate precipitation to guarantee plant development and good fructification. <em>Actinidia chinesis</em> or golden kiwifruit are smooth skinned, feature golden flesh and are a more recent introduction into the global market. Kiwifruit …

Changes in loblolly pine seedling root growth potential over time, during cold storage, and among half-sib families
… or prior to the accumulation of at least 400 chilling hours. Seedling RGP increased in the early-winter to a late-February peak, and then decreased when spring shoot elongation occurred during the RGP tests. Similar trends over time were noted with seedlings removed from cold storage during …

Effect of Evapotranspiration Rate on Almond Yield in California
… after adjusting for location, precipitation, chilling hours and year was made. The R<sup>2</sup>of this model 62.6%, and all the variables used had a p2was higher than Model 1; however, there was high unexplained variability (47.4%). Model 3 evaluated within-year variation. A regression …

Unraveling Molecular Mechanisms Regulating Dormancy and Bloom Time in Apple (Malus × domestica Borkh)
… in apple can only occur after fulfillment of chilling and heat requirements. In the Mid-Atlantic region, dormancy release and bud break of apple often coincide with late-spring freezes that cause severe damages to flowers, and small fruitlets. Therefore, the present study aimed to better …

Effect of chilling, hydrogen cyanamide, hot water and bud scale removal on bud break of 'Tifblue' rabbiteye blueberry
… in warm areas. The delay is due to a lack of the chilling which is required to break bud endodormancy. Bud endodormancy can be overcome in some species by treatments such as H<sub>2</sub>CN<sub>2</sub>, heat, and bud scale removal. We tested the effects of chilling, H<sub>2</sub>CN<sub>2</sub>, …
