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.

Cold hardiness dynamics predict budbreak and associated low-temperature threats in grapevine. [PDF]

New Phytol
Summary Dormant buds of temperate woody perennial plants must attain cold hardiness to survive winters and timely lose it in spring to break bud while avoiding damage from low temperatures and late frosts. Therefore, we asked: Can a cold hardiness model be used to predict budbreak?

Leaf seasonal osmotic adjustment is not driven by temperature or water deficit. [PDF]

Plant J
SUMMARY Osmotic adjustment (OA), the active accumulation of osmolytes in plant cells, plays a crucial role in plant‐drought response. OA occurs throughout the growing season, but the seasonal effects of temperature and water status on OA remain unclear. We investigated grapevine (Vitis vinifera) leaves' regulation of osmotic potential over time, across

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 ...

Kiwifruit SVP2 gene prevents premature budbreak during dormancy [PDF]

Journal of Experimental Botany, 2017
Overexpression of SVP2 in kiwifruit delays budbreak before sufficient winter chilling. SVP2-mediated vegetative growth restriction involves stress response pathways, and commonalities exist between Arabidopsis and kiwifruit SVP targets.

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.

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.

Budbreak of pecan cultivars subject to artificial chill

Revista Ceres, 2023
ABSTRACT Chill is a limiting factor in commercial production of temperate fruit due to their dormancy mechanism. Thus, knowledge of chill requirements of cultivars is important to reach successful production. This study aimed at evaluating responses given by different pecan cultivars subject to artificial chill.

Budbreak and Winter Injury in Exotic Firs [PDF]

HortScience, 2006
Seventeen Abies species were evaluated for budbreak and frost injury at four locations in Michigan. Freeze tests were conducted on four species growing at the Horticulture Teaching and Research Center to determine cold hardiness levels during winter. Species differed (P ≤ 0.0001) in their days to budbreak at all locations.

Multi-Task Learning for Budbreak Prediction

, 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 ...
