Acrotonia da brotação de macieira em região de inverno ameno
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilPrograma de Pós-Graduação em AgronomiaUTFPR, 2017-02-02)
During dormancy, temperate plants temporarily stops visible growth. In apple trees, it is known that temperature is the environmental factor that most influences dormancy. The plant requires low temperatures to ...
Determinación de los requerimientos térmicos otoño-invernales en almendro (Prunus amygdalus Batsch) cv. Guara y cv. MarinadaDetermination of Autumn-Winter Thermal Requirements in Almond (Prunus amygdalus Batsch) cv. Guara and cv. Marinada
(Universidad de Colima, México, 2022)
Objetivo: determinar en almendros cv. Guara y cv. Marinada la fecha de transición entre
endodormancia y ecodormancia, y los requerimientos de frío y de calor para la salida del
reposo otoño-invernal. Materiales y ...
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 ...
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 ...
Análises biológicas e bioquímicas na dinâmica da dormência de macieiras em Palmas – PR
(Universidade Tecnológica Federal do ParanáPato BrancoPrograma de Pós-Graduação em Agronomia, 2014-02-27)
The present study aimed to characterize the dormancy dynamics and the variation of
carbohydrates and other shoots constituents of apple tree with low ('Eva') and high
chilling requirement ('Fuji Suprema' and 'Galaxy'), ...
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 ...
Dormant but Active: Chilling Accumulation Modulates the Epigenome and Transcriptome of Prunus avium During Bud Dormancy
(2020)
Temperate deciduous fruit tree species like sweet cherry (Prunus avium) require long periods of low temperatures to trigger dormancy release and flowering. In addition to sequence-based genetic diversity, epigenetic variation ...
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 ...
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 ...
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 ...
