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 ...
The roles of light and pericarp on seed dormancy and germination in feral Raphanus sativus (Brassicaceae)
(Wiley, 2019-08-19)
The timing of seed germination may determine the success of a weed species in an agroecosystem, and its expression is modulated by environmental conditions, but also by seed physiology and anatomy. The aims of this study ...
Physical seed dormancy in native legume species of Argentina
(Sociedad Argentina de Botánica, 2016-03)
Leguminosae is a family with high value of use for food, medicine, forage, ornamental and restoration ecology purposes. One obstacle for the use and management of many legume species is the presence of seeds with physical ...
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 ...
Effect of Scarification, Self-Inhibition, and Sowing Depth on Seed Germination of Lupinus campestris
(Instituto de Investigaciones Agropecuarias, INIA, 2010)
Disturbance as a factor in breaking dormancy and enhancing invasiveness of African grasses in a Neotropical Savanna
(Soc Botanica Brasil, 2016-01-01)
The Cerrado is threatened by wildfires and invasive species. We aimed to evaluate in laboratory conditions whether temperature fluctuation at the soil surface, resulting from the absence of vegetation due to fire, can ...
Dormición física y conservación ex situ de semillas de Amburana cearensis y Myroxylon peruiferum [Fabaceae] = Physical dormancy and ex situ seed conservation of Amburana cearensis and Myroxylon peruiferum (Fabaceae)
(2015-06)
Amburana cearensis y Myroxylon peruiferum son dos especies nativas del noroeste argentino que se encuentran amenazadas por la explotación de su madera, siendo prioritario establecer programas de manejo, restauración ecológica ...
Fire and legume germination in a tropical savanna: ecological and historical factors
(2019-07-08)
BACKGROUND AND AIMS: In many flammable ecosystems, physically dormant seeds show dormancy-break patterns tied to fire, but the link between heat shock and germination in the tropical savannas of Africa and South America ...
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 ...
Light sensitivity changes during dormancy induction in Polygonum aviculare L. seeds: development of a predictive model of annual changes in seed-bank light sensitivity in relation to soil temperature
(Wiley Blackwell Publishing, Inc, 2020-12)
Seeds of weed species require light to terminate dormancy and give way to germination. It is documented that sensitivity to light in Polygonum aviculare seeds increases during dormancy release. However, it is not known ...
