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. ...
Hypoxia and hydrogen cyanamide induce bud-break and up-regulate hypoxic responsive genes (HRG) and VvFT in grapevine-buds
(Springer, 2012)
It has been reported that dormancy-breaking
compound hydrogen cyanamide (HC) stimulates the fermentative
pathway and inhibits respiration in grapevinebuds,
suggesting in this way, that a respiratory stress must
be ...
The dormancy-breaking stimuli “chilling, hypoxia and cyanamide exposure” up-regulate the expression of a-amylase genes in grapevine buds
(Elsevier, 2014)
It has been suggested that respiratory stress is involved in the mechanism underlying the dormancybreaking
effect of hydrogen cyanamide (H2CN2) and sodium azide in grapevine buds; indeed, reductions
in oxygen levels ...
Similarities between natural and chemically induced bud-endodormancy release in grapevine Vitis vinifera L.
(ELSEVIER SCIENCE BV, 2010-05-19)
Bud-break in grapevines (Vitis vinifera L) can be poor and uneven in locations that have warm winters
with insufficient chilling. Growers in these regions use hydrogen cyanamide (HC), a dormancy-breaking
compound, to ...
Is GABA-shunt functional in endodormant grapevine buds under respiratory stress?
(Springer, 2013)
It has been suggested that a respiratory stress is
part of the mechanism through which the dormancy-breaking
compounds, hydrogen cyanamide (HC) and sodium
azide, induce the release of buds from the endodormancy
(ED) ...
Is erratic bud-break in grapevines grown in warm winter areas related to disturbances in mitochondrial respiratory capacity and oxidative metabolism?
(2007)
Bud-break and the length and depth of endodormancy (ED) were studied in grapevine (Vitis Vinifera L.) cv. Thompson Seedless (Sultana) grown in the Elqui (warm winter) and in the Maipo (temperate winter) valleys of north ...
Short day-photoperiod triggers and low temperatures increase expression of peroxidase RNA transcripts and basic peroxidase isoenzyme activity in grapevine buds
(2007)
Expression of peroxidase (Prx) RNA transcripts was studied in grapevine cv. Thompson seedless through use of semi-quantitative RT-PCR. In roots, the three Vitis vinifera Prx ESTs, reported in the genomic facility database ...
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 ...
The expression of VvPHYA and VvPHYB transcripts is differently regulated by photoperiod in leaves and buds of grapevines
(2009)
Light signals perceived by phytochromes (Phys) and cryptochromes (Crys) play key roles in plant growth and development and in photoperiod dependant process such as flowering, tuberization, seasonal growth cessation and ...
