Structural aspects of dormancy in quinoa (Chenopodium quinoa): Importance and possible action mechanisms of the seed coats
(Cambridge University Press, 2015-09)
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 ...
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 ...
Optimization of timing of next-generation emergence in Amaranthus hybridus is determined via modulation of seed dormancy by the maternal environment
(Oxford University Press, 2021-05)
The timing of emergence of weed species has critical ecological and agronomical implications. In several species, emergence patterns largely depend on the level of dormancy of the seedbank, which is modulated by specific ...
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 ...
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 ...
Heat shock effects on germination and seed survival of five woody species from the Chaco region
(Elsevier Gmbh, 2021-02)
In tropical dry forests, fire is a common disturbance and seed traits may drive regeneration of plant populations during these events. In this study, we aimed to (i) investigate whether the seed coat and/or fruit endocarp ...
Effect of storage temperature on dormancy release of sunflower (Helianthus annuus) achenes
(Cambridge University Press, 2018-06)
Published information regarding the effect of storage temperature on dormancy alleviation of sunflower achenes is contradictory and ambiguous. In the present study we explored the effect of temperature during dry storage ...
Differences in seed dormancy associated with the domestication of Cucurbita maxima: Elucidation of some mechanisms behind this response
(Cambridge University Press, 2017-11)
This work presents the results of physiological studies developed to understand modifications linked to the reduction of seed dormancy provoked by domestication processes. The experiments performed compared wild and ...
Dormancy in sunflower line A-3: The role of the pericarp
(Canadian Science Publishing, 2017-03)
Sunflower (Helianthus annuus L.) can often display seed dormancy, which causes a delay for immediate sowing. The final degree of “whole seed” dormancy is determined by the contributions of the tissues that comprise it, ...
