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 ...
Grapevine buds detection and localization in 3D space based on Structure from Motion and 2D image classification
(Elsevier Science, 2018-08)
In viticulture, there are several applications where 3D bud detection and localization in vineyards is a necessary task susceptible to automation: measurement of sunlight exposure, autonomous pruning, bud counting, type-of-bud ...
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 ...
Alterations in the pattern of peroxidase isoenzymes and transient increases in its activity and in H2O2 levels take place during the dormancy cycle of grapevine buds: The effect of hydrogen cyanamide
(2004)
Polymorphism of peroxidase (Px) and changes in its activity and in H 2O2 content were studied in buds of grapevine during dormancy. Three isoforms of Px were detected in bud-extracts, two basic and one acidic, however, the ...
Possible role of catalase in post-dormancy bud break in grapevines
(URBAN & FISCHER VERLAG, BRANCH OFFICE JENA, 2005-03)
Changes in the activity of catalase (Cat) and in the levels of H2O2 were followed throughout dormancy in buds of grapevines (Vitis vinifera L.). In grapevines grown in the Elqui valley in Chile, a region with warm-winters, ...
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. ...
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 ...
Relationship between endodormancy, FLOWERING LOCUS T and cell cycle genes in Vitis vinifera
(Springer, 2016)
Main conclusion In grapevines, the increased expression of VvFT, genes involved in the photoperiodic control of seasonal growth (VvAP1, VvAIL2) and cell cycle genes (VvCDKA, VvCDKB2, VvCYCA1, VvCYCB, VvCYCD3.2) in the shoot ...
Effect of leaf‐to‐fruit ratios on phenolic and sensory profiles of Malbec wines from single high‐wire‐trellised vineyards
(Wiley, 2020-08)
BACKGROUND: The single high‐wire system is a free canopy trellis system suitable for warm to hot climates. In a global warming scenario, it arouses as a technological solution since it prevents berry overheating and sunburn. ...
