Seed Storage and Germination of Three Grass Species: Effect of Spikelet Weight and Dormancy

Brazilian Archives of Biology and Technology
Dormancy is a plant strategy that distributes germination over time. Domestication changed this in many cultivated species. However, many still retain this characteristic because it has not been completely removed or domesticated, especially in apomictic

Soil organic carbon increase on conversion of native savanna to improved pasture in two regions of Colombia

Grassland Research, Volume 3, Issue 4, Page 318-330, December 2024.
Our study revealed how landscape transformation from native savanna to improved pastures increases soil organic carbon (SOC) in two regions of Colombia. The results show a significant change in SOC to along profile (0–60 cm), influenced by factors such as grass type, geographic conditions, and soil texture.

Wheat genetic resources have avoided disease pandemics, improved food security, and reduced environmental footprints: A review of historical impacts and future opportunities

Global Change Biology, Volume 30, Issue 8, August 2024.
This review presents examples of successful use of plant genetic resources including the relentless battle against wheat rust epidemics/pandemics, defending against diseases that jump species barriers like blast, biofortification giving nutrient‐dense varieties and the use of novel genetic variation for improving polygenic traits like climate ...

Herbage Yield and Nutritive Value of Selected Grasses in Subhumid Agroecological Environments in Ethiopia

International Journal of Agronomy, Volume 2024, Issue 1, 2024.
The introduction of improved forage varieties could play a crucial role in meeting the growing demand for livestock and livestock products in Ethiopia. However, different cultivars exhibit varied performance. Therefore, this study aimed to assess the performance of Brachiaria cultivars and other grass cultivars in two subhumid agroecological areas of ...

Manejo de campos de produção de sementes de Urochloa humidicola €˜comum€™: II - Efeito de práticas culturais

Boletim de Indústria Animal, 2015
Desde a década de 1970, sementes de Urochloa (syn. Brachiaria) humidicola €˜comum€™ têm constituído fração importante do mercado brasileiro de sementes de pastagens tropicais cultivadas. Maior parte dessas sementes provém de áreas de pastagens nas quais os animais são excluídos desde a primavera até a colheita, no verão.

Toxicity and Availability of Manganese in the Growth of Tropical Grasses in Contaminated Soil

Applied and Environmental Soil Science, Volume 2024, Issue 1, 2024.
Phytoremediation is a technique with high viability due to its low cost and minimal environmental impact. However, there are a few results regarding the use of tropical grasses in the phytoremediation of manganese (Mn), and there is no clear definition of which extractor is more suitable for assessing Mn availability in soils.
