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 ...
Pericarp-imposed dormancy in sunflower: Physiological basis, impact on crop emergence, and removal at an industrial scale
(Crop Science Society of America, 2016-03-15)
Sunflower (Helianthus annuus L.) achenes often display pericarp-imposed dormancy, which is long-lasting and causes serious problems to crop production and the seed industry. For this study we assessed an extensively used ...
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 ...
Effect of FLOWERING LOCUS C on seed germination depends on dormancy
(Csiro Publishing, 2017-03)
FLOWERING LOCUS C (FLC) has a major regulatory role in the timing of flowering in Arabidopsis thaliana (L.) Heynh. and has more recently been shown to influence germination. Here, we investigated the conditions under which ...
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 ...
