Maternal Environment Effects on Common Groundsel (Senecio vulgaris) Seed Dormancy
(WEED SCI SOC AMER, 2010)
Common groundsel adapts readily to new environments and selection pressures and has been variably described as both a winter and summer annual. We characterized germination response to temperature in seeds from populations ...
The role of domestication and maternal effects on seed traits of crop–wild sunflower hybrids (Helianthus annuus)
(Wiley, 2017-08-18)
Hybridization between crops and their wild relatives may promote the evolution of weeds. Seed germination and dormancy are the earliest life-history traits and are highly influenced by the maternal parent. However, the ...
Physiological and molecular mechanisms underlying the integration of light and temperature cues in Arabidopsis thaliana seeds
(Wiley, 2017-09-23)
The relief of dormancy and the promotion of seed germination are of extreme importance for a successful seedling establishment. Although alternating temperatures and light are signals promoting the relief of seed dormancy, ...
How does fire affect germination of grasses in the Cerrado?
(2020-01-01)
Fire is a frequent disturbance in the Cerrado and is one of the major factors affecting vegetation structure and diversity. Fire events open gaps within the herbaceous layer and increase temperature fluctuation in the soil ...
Digitaria sanguinalis seed dormancy release and seedling emergence are affected by crop canopy and stubble
(Wiley Blackwell Publishing, Inc, 2020-04)
Digitaria sanguinalis is a troublesome annual weed that causes important yield losses in different crops. Despite this, there is scarce information about different aspects of its biology under field conditions. New knowledge ...
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 ...
Seed dormancy and germination in different populations of the Argentinan endemic halophyte grass, Sporobolus phleoides (Poaceae: Chloridoideae)
(Csiro Publishing, 2016-09)
Sporobolus phleoides Hack. is an endemic grass of Argentina that is considered an important genetic resource for saline environments. Knowledge of its germination behaviour is an indispensable requirement for the future ...
Seed dormancy QTL identification across a Sorghum bicolor segregating population
(Springer, 2016-05)
Pre-harvest sprouting (PHS) in Sorghum bicolor is one of the main constrains for its production in the central region of Argentina, as grain maturation often coincides with rainy or high environmental humidity conditions. ...
Methods of overcoming dormancy in seeds and initial development of Black Wattle
(Universidade Federal de Santa Maria, 2020)
