PtoHY5 integrates photoperiodic signals with the ABA pathway to coordinate growth cessation and dormancy in Populus

Journal of Integrative Plant Biology, EarlyView.
In Populus, short days deactivate the growth‐promoting protein PtoHY5, turning off a growth accelerator and activating an abscisic acid‐driven brake. This directly couples growth cessation with dormancy, underscoring the role of abscisic acid in synchronizing these transitions for winter survival.

Endodormancy release in Norway spruce grafts representing trees of different ages

Tree Physiology, 2020
AbstractStudies addressing endodormancy release in adult trees are usually carried out using twigs detached from the trees in the experiments. Potential problems caused by cutting the root–shoot connection when detaching the twigs can be avoided by using grafts as the experimental material. We studied the effects of chilling on the endodormancy release

Tree growth response and adaptation to climate change and climate extremes: From canopy to stem

Journal of Integrative Plant Biology, Volume 68, Issue 8, Page 2388-2415, August 2026.
This review synthesizes the responses and adaptations of tree growth, including canopy phenology, intra‐annual wood formation dynamics, and annual stem growth, to climate change and climate extremes. It highlights key knowledge gaps for future research to support sustainable forest management and enhance forest carbon storage under ongoing climate ...

Frost induced changes in enzyme activities and carbohydrate content in the spurs of some pear cultivars during the dormancy

International Journal of Horticultural Science, 2008
Frost tolerance of pear cultivars was checked after artificial cold treatment in 2003-2005. Limbs collected during the endodormancy were exposed in a climatic chamber for 24 hours to —25; —28 °C, while those collected in the ecodormancy were kept at —15 ...

Chilling Accumulation Shapes Transcriptomic Responses to Warming Exposure During Grapevine Deacclimation

Physiologia Plantarum, Volume 178, Issue 4, July/August 2026.
ABSTRACT During winter, grapevine (Vitis vinifera) bud dormancy and cold hardiness are regulated by complex interactions between chilling accumulation and warm temperature cues. However, the molecular mechanisms underlying physiological transitions during winter remain poorly understood.

Bud dormancy evolution in apple genotypes with contrasting chilling requirements

Revista Brasileira de Fruticultura, 2022
This work evaluates how thermal regimes with constant or oscillating temperatures affect the onset and overcome of endodormancy in apple buds with low (‘Castel Gala’) and high (‘Royal Gala’) chilling requirements.

(In)determinacy in Woody Plants: Limits and Opportunities for Timing Growth in a Changing Climate

Ecology Letters, Volume 29, Issue 6, June 2026.
Tree growth is shaped not only by temperature and water availability, but also by intrinsic developmental programming that constrains when and how long meristems remain active. We use (in)determinacy—the continuum from fixed, preformed seasonal growth to more flexible, ongoing organ production—to predict how species will differ in risk exposure ...

Relationship Between Endodormancy and Cold Hardiness in Grapevine Buds

Journal of Plant Growth Regulation, 2015
Endodormancy (ED) and cold hardiness (CH) are two strategies utilized by grapevine (Vitis vinifera L.) buds to survive unfavorable winter conditions. Each phenomenon is triggered by different environmental cues—ED by short-day (SD) photoperiod and cold hardiness (CH) by low temperatures.

Temporal changes in the proanthocyanidins to anthocyanins ratio during dormancy associate with bloom time variations in peach

Current Plant Biology
Our previous research demonstrated that fall applications of ethephon, an ethylene-releasing plant growth regulator, delay bloom in peach, accompanied by changes in endogenous hormones, ROS, sugar metabolism, and transcriptomic profiles during bud ...

TESTING OF APRICOT GENOTYPES FOR THE REQUIREMENT OF COLD EXPOSURE (ENDODORMANCY) DURING THE VEGETATIVE BREAK [TESTOVÁNÍ GENOTYPŮ MERUNĚK NA POŽADAVEK EXPOZICE CHLADU (ENDODORMANCE) V DOBĚ VEGETAČNÍHO KLIDU] [PDF]

Vědecké Práce Ovocnářské
Temperate fruit species need to accumulate a certain amount of cold, which is specific to the cultivar, to complete their life cycle during vegetative break (dormancy).
