Budbreak patterns and phytohormone dynamics reveal different modes of action between hydrogen cyanamide- and defoliant-induced flower budbreak in blueberry under inadequate chilling conditions.

PLoS ONE, 2021
Under inadequate chilling conditions, hydrogen cyanamide (HC) is often used to promote budbreak and improve earliness of Southern highbush blueberry (Vaccinium corymbosum L. interspecific hybrids). However, HC is strictly regulated or even banned in some

Multi-Task Learning for Budbreak Prediction [PDF]

, 2023
Grapevine budbreak is a key phenological stage of seasonal development, which serves as a signal for the onset of active growth. This is also when grape plants are most vulnerable to damage from freezing temperatures. Hence, it is important for winegrowers to anticipate the day of budbreak occurrence to protect their vineyards from late spring frost ...

Modeling the Budbreak in Peaches: A Basic Approach Using Chill and Heat Accumulation

Agronomy, 2023
Phenological shifts in peaches have been observed over the last few years due to the fluctuation of the seasonal climate conditions experienced during dormancy, affecting orchard management practices and influencing production and harvest dates.

Evaluation of winter temperatures on apple budbreak using grafted twigs [PDF]

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.

EVAPORATIVE COOLING AND CYANAMIDE ON BUDBREAK AND MATURATION OF GRAPEVINE, CV. PERLETTE. [PDF]

HortScience, 1992
Chilling accumulation infuence dormancy of grapevines and determines budbreak. Under desert conditions, hydrogen cyanamide (H2CN2) improve bud opening. To increase even further the quantity and uniformity of bud break, the effect of fall evap rative cooling (EC) alone or in combination with H2CN2(2.5%v/v was evaluated.

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.

Is It Cold Enough? Effects of Artificial and Natural Chilling on Budbreak and Frost Hardiness in Acer saccharum (Marsh.). [PDF]

Physiol Plant
ABSTRACT A crucial part of the phenological cycle in temperate and boreal trees is the exposure to chilling temperatures releasing endodormancy, which allows the trees to react to external signals and resume growth in spring. We compared the effect of artificial and natural chilling on endodormancy break and frost hardiness of sugar maple (Acer ...

Thresholds for spring freeze: measuring risk to improve predictions in a warming world. [PDF]

New Phytol
Summary 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.

Selection for Increased Budbreak in Apple [PDF]

Journal of the American Society for Horticultural Science, 2003
Significant response to selection for budbreak number (NB) based on data recorded on 1-year-old shoots of young apple (Malus sylvestris (L.) Mill var. domestica (Borkh.) Mansf.) seedlings (Expt. I) and branches from adult seedling trees (Expt. II) has been demonstrated in clonally propagated seedling trees.
