The dormancy-breaking stimuli "chilling, hypoxia and cyanamide exposure" up-regulate the expression of α-amylase genes in grapevine buds
(2014)
It has been suggested that respiratory stress is involved in the mechanism underlying the dormancy-breaking effect of hydrogen cyanamide (H2CN2) and sodium azide in grapevine buds; indeed, reductions in oxygen levels ...
H2O2 is involved in the dormancy-breaking effect of hydrogen cyanamide in grapevine buds
(SPRINGER, 2008-06)
Hydrogen cyanamide (HC) is widely used
to induce the breakage of endodormancy (ED) in
grape and other deciduous fruit crop, though its
mechanism of action is poorly understood. Applications
of HC to grapevine buds ...
ABA represses the expression of cell cycle genes and may modulate the development of endodormancy in grapevine buds
(Frontiers Media S.A., 2017)
© 2017 Vergara, Noriega, Aravena, Prieto and Pérez. Recently, the plant hormone abscisic acid (ABA) has been implicated as a key player in the regulation of endodormancy (ED) in grapevine buds (Vitis vinifera L). In this ...
Relationship Between Endodormancy and Cold Hardiness in Grapevine Buds
(Springer, 2016)
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 ...
Abscisic acid (ABA) and low temperatures synergistically increase the expression of CBF/DREB1 transcription factors and cold-hardiness in grapevine dormant buds
(Oxford University Press, 2019)
Background and Aims: It has been reported that low temperatures (LTs) and the plant hormone abscisic acid (ABA) induce the expression of CBF/DREB1 transcription factors in vegetative tissues and seedlings of Vitis vinifera ...
Image classification for detection of winter grapevine buds in natural conditions using scale-invariant features transform, bag of features and support vector machines
(Elsevier, 2017-04)
In viticulture, there are several applications where bud detection in vineyard images is a necessary task, susceptible of being automated through the use of computer vision methods. A common and effective family of visual ...
Rootstock on production and quality of 'Niagara Rosada' grapevine
(Soc Brasileira Fruticultura, 2018-01-01)
In Brazil, the producers have changed used rootstocks to get more vigor to scion. Rootstocks change the distribution of bud fruitfulness over grapevine shoots and the expression of the bud fruitfulness into fruit yield. ...

(Elsevier, 2014)
It has been suggested that respiratory stress is involved in the mechanism underlying the dormancybreaking

On the mechanism of dormancy release in grapevine buds: A comparative study between hydrogen cyanamide and sodium azide
(2009)
Sodium azide (NaN3), a well-known inhibitor of mitochondrial respiration, stimulated bud-dormancy release in grapevines similar to hydrogen cyanamide (HC), while HC, a well-known dormancy release agent, inhibited the O2 ...
Hypoxia induces H2O2 production and activates antioxidant defence system in grapevine buds through mediation of H 2O2 and ethylene
(2012)
Paradoxically, in eukaryotic cells, hydrogen peroxide (H2O 2) accumulates in response to oxygen deprivation (hypoxia). The source of H2O2 under hypoxia varies according to the species, organs, and tissue. In nonphotosynthetic ...
