Timing of seed dispersal and seed dormancy in Brazilian savanna: Two solutions to face seasonality
(2018-05-11)
Background and Aims The relationship between fruiting phenology and seed dispersal syndrome is widely recognized; however, the interaction of dormancy classes and plant life-history traits in relation to fruiting phenology ...
Molecular mechanisms underlying the entrance in secondary dormancy of Arabidopsis seeds
(Wiley, 2016-01)
As seasons change, dormant seeds cycle through dormant states until the environmental conditions are favourable for seedling establishment. Dormancy cycle is widespread in the plant kingdom allowing the seeds to display ...
Environmental control of dormancy in quinoa (Chenopodium quinoa) seeds: Two potential genetic resources for pre-harvest sprouting tolerance
(Cambridge University Press, 2011-06)
Pre-harvest sprouting (PHS) is a serious risk when adapting quinoa (Chenopodium quinoa) seed production to different temperate environments. Two quinoa accessions, 2-Want and Chadmo were evaluated under field conditions ...
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 ...
The role of seed water content for the perception of temperature signals that drive dormancy changes in Polygonum aviculare buried seeds
(Csiro Publishing, 2020-08)
Seedling emergence in the field is strongly related to the dynamics of dormancy release and induction of the seed bank, which is mainly regulated by soil temperature. However, there is limited information on how ...
Echinochloa crus-galli seed physiological dormancy and germination responses to hypoxic floodwaters
(Wiley Blackwell Publishing, Inc, 2019-07-06)
Hypoxic floodwaters can seriously damage seedlings. Seed dormancy could be an effective trait to avoid lethal underwater germination. This research aimed to discover novel adaptive dormancy responses to hypoxic floodwaters ...
Pre-harvest sprouting and grain dormancy in sorghum bicolor: What have we learned?
(Frontiers Media S.A., 2018-06)
The possibility of obtaining sorghum grains with quality to match the standards for a diversity of end-uses is frequently hampered by the susceptibility to pre-harvest sprouting (PHS) displayed by many elite genotypes. For ...
Spontaneous Gene Flow between Cultivated and Naturalized Vicia villosa Roth Populations Increases the Physical Dormancy Seed in a Semiarid Agroecosystem
(MDPI, 2021-05)
Hairy vetch (Vicia villosa Roth) is the second most cultivated vetch worldwide being used as a forage and cover crop. As it is not domesticated, it displays several wild traits including seed dormancy. The physical seed ...
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 ...
