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 ...
Banco de sementes do solo: o estado da arte
(Universidade Tecnológica Federal do ParanáFrancisco BeltraoBrasilEngenharia AmbientalEngenharia AmbientalUTFPR, 2015-11-24)
The modern lifestyle has caused many negative impacts on the environment, promoting the exhaustion of natural resources, pollution and changes in natural environmental conditions. In this way, it shows up valuable development ...
Grazing impact on desert plants and soil seed banks: implications for seed-eating animals
(Gauthier-Villars/Editions Elsevier, 2014-05)
We assess whether the knowledge of livestock diet helps to link grazing effects with changes in plant cover and soil seed bank size, aiming at inferring the consequences of grazing on seed-eating animals. Specifically, we ...
Tolerance to desiccation and cryopreservation of seeds of seven south american llex species
(American society for horticultural science, 2018-06)
This research aimed at evaluating the desiccation tolerance and ability to withstand cryostorage of intact seeds of seven South American Ilex species, and comparing different methodologies for in vitro germination of fresh ...
Aboveground vegetation and perennial grass seed bank in arid rangelands disturbed by grazing
(Elsevier, 2015)
Recruitment by seeds can be an important mechanism for recovery of plant communities following disturbance. Our objective was to assess the density and spatial patterning of perennial grass (highly preferred by herbivores) ...
Soil seed bank in and between vegetation patches in arid Patagonia, Argentina
(Elsevier Science, 2009-02)
This study was conducted at two sites, 1.5 km from 1 to another in arid Argentina (39◦S, 69◦W). Vegetation is distributed in patches. Four microenvironments can be identified in the soil surface of these patches, and the ...

(Universidade Federal de Santa MariaBRRecursos Florestais e Engenharia FlorestalUFSMPrograma de Pós-Graduação em Engenharia Florestal, 2009-02-27)
This study evaluated the mechanisms of natural regeneration represented by seeds rain, seeds bank of the soil and the regeneration vegetation, considering the
seedlings bank and the established regeneration, in a fragment ...
