Dormancy attributes in sunflower achenes (Helianthus annuus L.): II. Sowing date effects
(Crop Science Society of America, 2021-11)
Sunflower (Helianthus annuus L.) seed industry needs nondormant seeds (i.e., seeds with the capacity to germinate in a wide range of environmental conditions) for processing and packaging. Thus, the presence of persistent ...
Structural aspects of dormancy in quinoa (Chenopodium quinoa): Importance and possible action mechanisms of the seed coat
(2015-05)
Two possible sources of resistance to pre-harvest sprouting were evaluated in quinoa. They showed dormancy at harvest and significant variations in dormancy level in response to environmental conditions experienced during ...
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 ...
Dormancy and germination responses of kiwifruit (Actinidia deliciosa) seeds to environmental cues
(Cambridge University Press, 2016-12)
Seed germination of the kiwifruit (Actinidia deliciosa A. Chev. C.F. Liang and A.R. Ferguson), a deciduous, perennial vine, is low because of seed dormancy. The main purpose of this study was to characterize kiwifruit seed ...
Dormancy breakage and germination are tightly controlled by hypoxic submergence water on Echinochloa crus-galli seeds from an accession resistant to anaerobic germination
(Cambridge University Press, 2020-12)
In wetlands, dormancy may be a key functional trait enabling seeds to avoid underwater germination, which could be lethal for seedling establishment. Our objectives were to find out (i) if shallow dormant (i.e. conditionally ...
Vicia villosa ssp. villosa Roth field emergence model in a semiarid agroecosystem
(Wiley Blackwell Publishing, Inc, 2018-03)
Hairy vetch (Vicia villosa Roth) is a winter annual legume cultivated for pasture and hay with the capability for natural reseeding. Vicia villosa increases N concentrations in the soil, thus contributing to the sustainability ...
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 ...
Seed anatomy and water uptake and their relation to seed dormancy of Ormosia paraensis DuckeAnatomia de sementes e absorção de água e sua relação com a dormência de sementes de tento (Ormosia paraensis Ducke)
(2018-07-01)
Ormosia paraensis Ducke has ornamental seeds widely used in the manufacture of bio-jewels and wood used in the furniture industry. For seedling production, the information on its seed physiology is scarce. Thus, the aim ...
Seed dormancy and hybridization effect of the invasive species, Helianthus annuus
(Wiley Blackwell Publishing, Inc, 2014-01)
Helianthus annuus is an invasive alien species naturalised in the central region of Argentina where it shares an extended area with the sunflower crop. As this species has also invaded several other sunflower crop growing ...
Maternal environment and dormancy in sunflower: The effect of temperature during fruit development
(Elsevier Science, 2017-01)
A rapid and uniform germination in the field is an important requirement for commercial hybrid sunflower seed. Persistence of dormancy after harvest can negatively affect this aspect of seed quality, and seed lots with ...
