The chilling requirement of subtropical trees is fulfilled by high temperatures: A generalized hypothesis for tree endodormancy release and a method for testing it

, 2021
Spring phenology is a key phenomenon mediating the effects of climate change on terrestrial plants and ecosystems, but in regard to subtropical trees, the dormancy mechanisms that regulate spring phenology are still poorly understood.

Hormones and Endodormancy Induction in Woody Plants

Journal of Crop Improvement, 2004
Summary The scope of this review is limited to hormonal involvement in the induction of woody bud endodormancy and does not address dormancy maintenance or release. Knowledge of hormonal regulation of processes has become increasingly more complex, particularly with recent findings of auxin- and ethylene-triggered abscisic acid induction revealing many

Chilling and gibberellin acids hyperinduce β-1,3-glucanases to reopen transport corridor and break endodormancy in tree peony (Paeonia suffruticosa).

Plant physiology and biochemistry : PPB, 2021
Bud endodormancy is accompanied by transport channel apertures blockage through callose deposition, and its resume to growth requires evoking β-1,3-glucanases (BGs) to unchoke the conduit.

Integrating the analysis of mitoflash, energy substrate, and hormones to advance understanding of Magnolia endodormancy mechanisms.

International Journal of Biological Macromolecules
Flower bud dormancy ensures trees can survive winter and successfully flower and reproduce in early spring, yet its activation mechanism remains elusive.

Sucrose accumulation and endodormancy are synchronized events induced by the short-day photoperiod in grapevine buds.

Plant physiology and biochemistry : PPB, 2022
At the end of the summer season, grapevine buds (Vitis vinifera L) grown in temperate climates enter a state of winter recess or endodormancy (ED), which is induced by the shortening of the photoperiod, and during this period, the buds accumulate sucrose.

PsSOC1 is involved in the gibberellin pathway to trigger cell proliferation and budburst during endodormancy release in tree peony.

New Phytologist
Tree peony (Paeonia suffruticosa) undergoes bud endodormancy, and gibberellin (GA) pathway plays a crucial role in dormancy regulation. Recently, a key DELLA protein PsRGL1 has been identified as a negative regulator of bud dormancy release. However, the

Ecodormancy or Endodormancy? PtTFL2 as the Key Switch in Regulating Dormancy Transitions in Pinus tabuliformis

Plant, Cell and Environment
In the wild, plants face diverse harsh environments, including extreme temperatures, which compel them to evolve complex mechanisms to sense these environmental changes and adjust their growth accordingly.

Characteristics of bud endodormancy and physiology in Quercus acutissima seedlings growing in an environment with low chill availability

Journal of Forest Research
Global warming is expected to hamper bud endodormancy. Understanding endodormancy in low chill availability environments helps to predict endodormancy in future winters.

MODELS FOR QUANTIFYING EFFECTIVE WINTER CHILL ON APPLE ENDODORMANCY

Acta Horticulturae, 2010
Under southern Uruguayan conditions (34°37'SL;56°11'O, 40 m) winter chilling requirements are not always satisfied for the main commercial apple (Malus domestica Borkh) cultivars. The use of chemical rest breaking agents (mineral oils and hydrogen Cyanamid) to compensate these requirements is widely used. Therefore winter chill quantification should be
