A framework for the interpretation of temperature effects on dormancy and germination in seed populations showing dormancy
(Cambridge University Press, 2015-06)
Temperature is a key factor affecting both dormancy and germination. In non-dormant seeds, when temperature is within the thermal range permissive for germination, it just regulates germination velocity, while in seeds ...
On the germination and dormancy of dispersal units of Brachiaria decumbens STAPF
(Inst Tecnologia Parana, 1996-01-01)
The effect of light and temperature on germination of Brachiaria decumbens as well as the action of some dormancy breaking chemicals were tested. Two seed batches stored different times were used. The results show that ...
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 ...
Temperature-dependent regulation of induction into secondary dormancy of Polygonum aviculare L. seeds: A quantitative analysis
(Elsevier Science, 2017-05)
In seeds of many summer annuals low temperatures under moist conditions provoke dormancy release while high temperatures induce secondary dormancy. Seed dormancy level establishes the range of temperatures under which ...
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 ...
GERMINATION AND DORMANCY IN SEEDS OF Sorghum halepense AND Sorghum arundinaceum
(Univ Federal Vicosa, 2015-04-01)
Light, temperature and dormancy are factors that influence the germination of seeds and are strictly linked to the emergence of weeds. The objective of this work was to assess the germination of Sorghum arundinaceum and ...
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 ...
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 ...
