Predicting the date of budbreak of grapevine grown in the « Serra Gaucha » region

OENO One, 2003
Predicting the date of budbreak allows a more organized and rational pruning, defining lire time for winter phythosanitary treatments and, if necessary, the application of products to improve homogeneous sprouting and to increase the percentage of ...

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 ...

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?

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.

Similar Relative Carbon Costs for Construction and Storage of Sun and Shade Branches in Mature Temperate Trees. [PDF]

Plant Cell Environ
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

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

Multi-Task Learning for Budbreak Prediction

CoRR, 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 ...

Delaying grapevine budbreak to prevent spring freeze damage impacts Lemberger wine flavour compounds under variable weather conditions

OENO One, 2023
Delaying grapevine budbreak through viticultural management practices is a promising method to prevent spring freeze damage for small vineyards. However, in cool-climate regions, delaying budbreak can potentially delay fruit development and maturation ...

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.

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
