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 ...
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 ...
Dormancy attributes in sunflower achenes (Helianthus annuus L.): I. Intraspecific variability
(Crop Science Society of America, 2021-11)
Cultivated sunflowers (Helianthus annuus L.) display variable degrees of achene dormancy at harvest and persistence during storage, interfering with high-quality hybrid seed production. Information on intraspecific variability ...
Spontaneous dormancy protects Trypanosoma cruzi during extended drug exposure
(eLife Sciences, 2018-03-26)
The ability of the Chagas disease agent Trypanosoma cruzi to resist extended in vivo exposure to highly effective trypanocidal compounds prompted us to explore the potential for dormancy and its contribution to failed drug ...
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 ...
Host plant stimuli effects on survival and duration of dormancy of Rhagoletis zoqui, Rhagoletis completa (Diptera: Tephritidae) and associated parasitoids
(Cambridge University Press, 2022-06)
Tephritid fruit flies in the genus Rhagoletis bridge between predictable periods of fruit availability by becoming dormant. To cope with acyclic unpredictable events (e.g., frost, mast seeding, etc), a proportion of the ...
Understanding dormancy breakage and germination ecology of Cynara cardunculus (Asteraceae)
(Wiley Blackwell Publishing, Inc, 2018-12)
Cynara cardunculus is a troublesome weed in temperate grazing lands. Cynara cardunculus achenes are usually dormant at dispersal and require alternating temperatures to terminate dormancy and germinate. Laboratory and ...
The Effect of Seasonal Humidity on Survival and Duration of Dormancy on Diverging Mexican Rhagoletis pomonella (Diptera: Tephritidae) Populations Inhabiting Different Environments
(Entomological Society of America, 2019-07)
Phytophagous insects synchronize emergence with plant phenology by engaging in dormancy during periods of host scarcity and environmental stress. Regulation of dormancy is achieved through response to seasonal cues. While ...
