Processing in the quality of tanzania grass seeds
(2016-01-01)
The available research concerning the processing of grass seeds is scarce, despite its fundamental importance for national and international agribusiness. The objective of this project was to evaluate the effects of ...
Continuous grazing disrupts desert grass-soil seed bank composition under variable rainfall
(Springer, 2021-02)
Long-term field studies help unveil mechanisms of grass soil seed bank (SSB) persistence and resilience. We wonder whether grazing is a disruptive force that changes grass SSB composition and size, while heavy rainfall is ...
SEED CONDITIONING PROCESS IN THE SANITARY QUALITY OF MARANDU GRASS SEEDS
(Univ Federal Uberlandia, 2020-05-01)
The purpose of seed conditioning process is to separate seeds and their associated structures into different fractions and retain only good and healthy seeds. Thus, the aim of this study was to evaluate the effects the ...
The presence of invasive grasses affects the soil seed bank composition and dynamics of both invaded and non-invaded areas of open savannas
(2020-12-15)
One of the major threats to tropical savannas globally is the invasion by alien grasses. In systems frequently disturbed, individuals can be recruited from the seed bank, and areas under natural regeneration can be more ...
Grass seed production in the central Monte desert during successive wet and dry years
(Springer, 2010-05)
In desert regions, water availability triggers primary production, which determines seed production, the composition and size of soil seed reserves and the abundance and behaviour of seed-eating animals. In the central ...
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 ...
Variation in Cactaceae Seeds in the Soil as a Function of an Invasive Exotic Grass in Mona Island Reserve
(External Scientific Advisory Committe (ESAC), 2012)
INCIDENCE OF FUNGI IN MOMBASA GRASS SEEDS DURING THE STAGES OF THE SEED CONDITIONING PROCESS
(Soc Brasil Engenharia Agricola, 2019-03-01)
The objective of this study was to evaluate the effect of the seed conditioning process on the sanitary quality of Panicum maximum 'Mombasa' seeds. The seeds were sampled before processing and after exiting the seed blower ...
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 ...
Invasive exotic grasses and seed arrival limit native species establishment in an old-field grassland succession
(Springer, 2012-12)
Plant communities developing in abandoned semi-natural areas are being increasingly dominated by invasive exotic species. How these 'novel residents' affect re-colonisation by native perennial species, a process generally ...
