From phenology models to risk indicator analysis [PDF]

, 2010
In this paper we outline a phenology model for estimating budbreak and full bloom starting dates of sour cherry on the effective heat sums with reasonable accuracy. With the help of RegCM3.1 model the possible trends of the phenology timing in the middle

Elucidation of molecular and hormonal background of early growth cessation and endodormancy induction in two contrasting Populus hybrid cultivars

BMC Plant Biology, 2021
Background Over the life cycle of perennial trees, the dormant state enables the avoidance of abiotic stress conditions. The growth cycle can be partitioned into induction, maintenance and release and is controlled by complex interactions between many ...

Hydrogen Peroxide Increases during Endodormancy and Decreases during Budbreak in Grapevine (Vitis vinifera L.) Buds

Antioxidants, 2021
Changes in the level of hydrogen peroxide (H2O2) is a good indicator to monitor fluctuations in cellular metabolism and in the stress responses. In this study, the changes in H2O2 content during bud endodormancy (ED) and budbreak were analysed in ...

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

Evaluation of olive flowering at low latitutde sites in Argentina using a chilling requirement model [PDF]

, 2015
Research ArticleOlive production has expanded significantly from the Mediterranean Basin into the New World over the last two decades. In some cases, cultivars of European origin have been introduced at a large commercial scale with little previous ...

The Role of Threonine Deaminase/Dehydratase in Winter Dormancy in Sweet Cherry Buds

Nitrogen, 2023
The determination of the endodormancy release and the beginning of ontogenetic development is a challenge, because these are non-observable stages. Changes in protein activity are important aspects of signal transduction. The conversion of threonine to 2-

Detecting QTLs and putative candidate genes involved in budbreak and flowering time in an apple multiparental population [PDF]

, 2016
UMR AGAP - équipe AFEF - Architecture et fonctionnement des espèces fruitièresIn temperate trees, growth resumption in spring time results from chilling and heat requirements, and is an adaptive trait under global warming.

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.

Dinâmica da dormência de gemas de dois anos de macieira 'Imperial Gala' em região de baixa ocorrência de frio Dormancy dynamics of two year old buds of 'Imperial Gala' apple tree in a region of low chill occurence

Revista Brasileira de Fruticultura, 2004
O objetivo deste trabalho foi determinar a dinâmica da dormência de gemas em ramos de dois anos de macieira 'Imperial Gala' com ou sem frio suplementar durante o outono e inverno, cultivadas em Porto Amazonas - PR, região de baixa ocorrência de frio.

Dormancy in reproductive vegetative buds in creeping perennials dominating the agricultural weed flora in Scandinavia [PDF]

, 2013
Dormancy, which is the inability to initiate normal growth under otherwise favourable conditions, is an adaptation to escape sprouting prior to seasonal cold temperatures and/or drought in areas where winters are harsh or summers dry.
