Fire cues trigger germination and stimulate seedling growth of grass species from Brazilian savannas
(2019-01-01)
Premise: Although fire cues (high temperatures and smoke) influence seed germination in numerous species from fire-prone environments, their effects on seed germination of species from neotropical savannas are poorly ...
Photoperiod throughout the maternal life cycle, not photoperiod during seed imbibition, influences germination in Arabidopsis thaliana
(Botanical Society of America, 2017-04)
PREMISE OF THE STUDY: Plants adjust their phenology in response to seasonal cues experienced both by their parents and by themselves, and coordinating responses to these cues is necessary for expressing adaptive phenology. ...
Germination response of common annual and perennial forbs to heat shock and smoke treatments in the Chaco Serrano, central Argentina
(Wiley Blackwell Publishing, Inc, 2018-08)
Fire is a key ecological factor affecting plant dynamics. In the last few decades, fire occurrence in the Chaco region has increased noticeably, challenging the adaptive capacity of plants to regenerate after a fire. ...
Fire cue effects on seed germination of six species of northwestern Patagonian grasslands
(Copernicus Publications, 2012-09-06)
Postfire recruitment of seedlings has been attributed to a stimulation of germination by fire-related cues. The germination response to heat shock (80 °C-5 min), smoke (60 min), the combination of both factors and no heat ...
The effects of fire-related cues on seed germination and viability of helenium aromaticum (hook.) Hl bailey (asteraceae)
(EDICIONES UNIV, CONCEPCION, 2011)
Field-burn vs. fire-related cues: germination from the soil seed bank of a South American temperate grassland
(Cambridge University Press, 2020)
Fire and grazing are large-scale disturbances that shape the structure and function of open habitats. In temperate grasslands of southern South America, fire is used as a management tool to control tussock grasses and ...
Fire cues and germination of invasive and native grasses in the Cerrado
(Soc Botanica Brasil, 2020-01-01)
Fire-related cues may enhance seed recruitment in flammable ecosystems and differences in fire-germination responses of invasive vs. native species can drive the invasion process. We evaluated the effects of heat shock and ...
Heat and smoke affect the germination of flammable resprouters: Vellozia species in the Cerrado
(2019-01-01)
Fire is an important ecological factor shaping plant strategies. Plants that are not able to survive fire and rely on seed reproduction may have seeds adapted for surviving heat shock or their germination may even be ...
The effect of simulated heat-shock and daily temperature fluctuations on seed germination of four species from fire-prone ecosystems
(Soc Botanica Brasil, 2016-07-01)
Seed germination in many species from fire-prone ecosystems may be triggered by heat shock and/or temperature fluctuation, and how species respond to such fire-related cues is important to understand post-fire regeneration ...
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 ...
