Sprouting of paradormant and endodormant grapevine buds under conditions of forced growth: similarities and differences
(Springer Verlag, 2018)
© 2018, Springer-Verlag GmbH Germany, part of Springer Nature. Main conclusion: Bud-break assays under forced growth conditions suggest that a drop in ABA content and an increase in sugars are common features in the sprouting ...
ABA promotes starch synthesis and storage metabolism in dormant grapevine buds
(Elsevier GmbH, 2019)
© 2019 Elsevier GmbH In grapevine (Vitis vinifera L.) buds, the short day (SD)-photoperiod induces endodormancy and increases the level of ABA and the expression of ABA key biosynthesis genes, which suggests that ABA could ...
Hydrogen peroxide increases during endodormancy and decreases during budbreak in grapevine (Vitis vinifera L.) buds
(MDPI, 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 ...
ABA and its signaling pathway are involved in the cold acclimation and deacclimation of grapevine buds
(Elsevier B.V., 2019)
The grapevine (Vitis vinifera L.) buds as well as the buds of other deciduous fruit trees acclimate and deacclimate to the cold during the autumn-winter season. Cold acclimation (CA) is characterized by an increase in bud ...
Testing the Ferguson model for the cold-hardiness of dormant grapevine buds in a temperate and subtropical valley of Chile
(Springer, 2020)
A dynamic thermal time model (DTTM) has been developed to predict cold-hardiness in dormant grapevine buds, which uses
daily mean temperatures as the only input variable. However, it has been recently reported that ...
ABA biosynthesis genes are down regulated while auxin and cytokinin biosynthesis genes are up-regulated during the release of grapevine buds from endodormancy
(Springer, 2017)
Auxin–cytokinin (CK) interactions have been
extensively studied in the control of bud outgrowth in herbaceous
plants. However, in temperate woody plants where
the meristem of dormant buds can be repressed by either
exogenous ...
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 ...
Cell cycle genes are activated earlier than respiratory genes during release of grapevine buds from endodormancy
(Taylor & Francis, 2017)
Single-bud cuttings of Vitis vinifera L exposed to forced growing conditions were used to investigate the involvement of phytohormones, abscisic acid (ABA), auxin (Aux) and cytokinin (CK) in the release of buds from 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, ...
Relationship between bud cold hardiness and budbreak in two vitis vinifera L cultivars, chardonnay and thompson seedless
(Springer, 2021)
The lack of winter cold is a severe limitation for the cultivation of grapevines (Vitis vinifera L) in areas with warm winter climates. This phenomenon is currently becoming quite important due to global warming, which ...
