Participation of ascorbic acid in the dormancy establishment of poplar lateral branch buds
(Springer Tokyo, 2014-04-19)
This work studied the participation of ascorbic acid (AA) in the dormancy establishment of apical buds of poplar (Populus deltoides BARTRAM ex MARSHALL cv. Catfish 2) lateral branches. AA content was highest during the ...
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 ...
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 ...
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 ...
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 ...
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, ...
Kinetin establish the volatile chemical profile after rhizome dormancy is released in Curcuma zedoaria (Christm.) Roscoe
(Taylor & Francis Ltd, 2020-02-20)
The aim of this work was to provide information about kinetin effects on chemical volatile profile of Curcuma zedoaria (Christm.) Roscoe after several days of plant dormancy release. Rhizomes of C. zedoaria were immersed ...
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 ...
Dormancy in peach (Prunus persica) flower buds. V. Anatomy of bud development in relation to phenological stage
(Canadian Science Publishing, 2002-09)
Anatomical changes in the peach (Prunus persica (L.) Batsch.) flower buds were defined and then assessed and correlated with the phenological stage from early dormancy through to flower opening. The peach flower bud, unlike ...
