Cold hardiness mechanisms and modeling: existing approaches and future avenues. [PDF]

New Phytol
Summary Cold hardiness models are useful tools to predict cold damage in plants, such as those produced by unseasonal temperature cycles or by increased cold exposure. Although development of these models started about five decades ago, their applications remain limited.

Rethinking Model Transferability: Validity Domains as a New Approach to Delineate the Limits of Bloom Date Projections. [PDF]

Glob Chang Biol
Accurately predicting future phenology events in novel environmental conditions is a key challenge in modelling. Using first bloom observations of the Japanese Yoshino cherry across a temperature gradient, we calibrated process‐based and machine learning models at multiple locations and cross‐validated them to obtain the predictive performance for all ...

Provenance-Specific Chilling and Forcing Requirements Shape Spring Phenology in Three European Temperate Tree Species. [PDF]

Glob Chang Biol
Winter chilling is essential for dormancy release and spring budburst in temperate trees. Using a climate‐controlled experiment with three species and four European provenances spanning a broad latitudinal gradient, we show that reduced chilling delays budburst and decreases budburst success, with strong species‐ and provenance‐specific differences ...

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 ...

Identification of early and late flowering time candidate genes in endodormant and ecodormant almond flower buds [PDF]

Tree Physiology, 2020
AbstractFlower bud dormancy in temperate fruit tree species, such as almond [Prunus dulcis (Mill.) D.A. Webb], is a survival mechanism that ensures that flowering will occur under suitable weather conditions for successful flower development, pollination and fruit set.

Meta-analysis of RNA-Seq studies reveals genes with dominant functions during flower bud endo- to eco-dormancy transition in Prunus species

Scientific Reports, 2021
In deciduous fruit trees, entrance into dormancy occurs in later summer/fall, concomitantly with the shortening of day length and decrease in temperature. Dormancy can be divided into endodormancy, ecodormancy and paradormancy.

Towards a Physiological Modeling of Sweet Cherry Blossom

Horticulturae, 2023
For several years, there has been a need in phenological modeling to better account for physiological processes during the winter dormancy of woody plants, which is here addressed to the sweet cherry cultivar ‘Summit’ (Prunus avium L.).

Stability of the almond blooming date in a changing climate [PDF]

, 2011
Although global warming is increasing the medium air temperature over time, this negative temperature trend cannot be yet appreciated in some areas. Analysis of air temperatures in the Ebro Central Valley (Zaragoza, Spain) during the last 24 years shows ...

Endo-, Para-, and Ecodormancy: Physiological Terminology and Classification for Dormancy Research

HortScience, 1987
Abstract Plant dormancy has a major impact on the cultivation of plants, influencing such processes as seed germination, flowering, and vegetative growth. The diversity of plant tissues that exhibit, or contribute to the manifestation of, dormancy is great, and there appear to be numerous mechanisms of dormancy induction or release. This complexity was
