Thresholds for spring freeze: measuring risk to improve predictions in a warming world. [PDF]
New PhytolSummary Plant distribution and productivity are shaped by environmental stressors, particularly freezing events in extra‐tropical regions. In early spring, a progressive loss of cold hardiness with phenological development leaves emerging tissues vulnerable to freezing events.

Chilling Affects Budbreak of Ginkgo biloba L. [PDF]
Journal of Environmental Horticulture, 2003 Abstract The effects of chilling and heat on budbreak of Ginkgo biloba L. seedlings were evaluated in a study initiated on October 1, 1999, and terminated on April 8, 2002. Chilling was a determinate factor in foliar budbreak for G biloba. Thirteen levels of chilling were applied to trees in increments of 100 hours, with twelve replications per

Effect of a Late Spring Application of Hydrogen Cyanamide on High-Chill Peaches
Agronomy, 2019 Due to a record low chilling accumulation in the winter of 2016−2017, many high-chill peach cultivars displayed almost no budbreak by mid-April of 2017 in central Georgia, USA, where budbreak usually occurs around mid-March.

Chilling and Heating Model for Pecan Budbreak [PDF]
Journal of the American Society for Horticultural Science, 1993 Chilling and heating effects on budbreak of pecan [Carya illinoinensis (Wangenh.) K. Koch] trees were examined by linear regression analyses from experimental data and from records of budbreak dates over a wide geographic range.

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).

Effect of Chemical Defoliation on the Budbreak of `Golden Delicious' Apple [PDF]
HortScience, 1995 During 1993–94, in an area with a subtropical climate, 1500 m elevation, and 300 mm of precipitation, an experiment with `Golden Delicious' apples/MM.111 under irrigation was conducted with 11 treatments with three replications in a completely randomized complete-block design: T1, manual defoliation (27 Sept.); T2, 1% CuSO

Hydrogen Cyanamide Advances Pecan Budbreak and Harvesting [PDF]
Journal of the American Society for Horticultural Science, 1993 Dormant season sprays of hydrogen cyanamide applied to pecan [Carya illinoinensis (Wangenh.) K. Koch] trees advanced budbreak, flowering, and shuck dehiscence. Hydrogen cyanamide was applied to dormant branches at ≈60, 45, 30, and 15 days before normal vegetative budbreak at rates of 0, 120 ...

Chilling Duration Affects Foliar Budbreak Of Linden Cultivars [PDF]
HortTechnology, 2002 A study evaluating the effects of varying levels of chilling on foliar budbreak of linden ( Tilia spp.) culivars was initiated in 1999 in Auburn, Ala. [lat. 32°36'N, long. 85°29'W, elevation 709 ft (216m), USDA Hardiness Zone 8a]. Littleleaf linden ( T. cordata
