Ethanol and hormones in physiological conditioning on germination and seed dormancy of Urochloa humidicola cv. Llanero

Journal of Seed Science, 2022
Abstract: Seed conditioning improves germination uniformity, speed, and dormancy release. This work aimed the study the physiological conditioning of Urochloa humidicola cv. Llanero, using two lots of dormant seeds conditioned by imbibition with water, commercial bioregulator (auxin, gibberellin - 0.144 mM and cytokinin), gibberellin (0.144 and 1.44 mM)

The barrier to radial oxygen loss impedes the apoplastic entry of iron into the roots ofUrochloa humidicola

Journal of Experimental Botany, 2021
AbstractLack of O2 and high concentrations of iron (Fe) and manganese (Mn) commonly occur in waterlogged soils. The development of a barrier to impede radial O2 loss (ROL) is a key trait improving internal O2 transport and waterlogging tolerance in plants. We evaluated the ability of the barrier to ROL to impede the entry of excess Fe into the roots of

CGIAR Operations under the Plant Treaty Framework

Crop Science, Volume 59, Issue 3, Page 819-832, May–June 2019., 2019
The history of CGIAR and the development and implementation of the International Treaty on Plant Genetic Resources for Food and Agriculture (“Plant Treaty”) are closely intertwined. In accordance with the agreements that 11 CGIAR centers signed with the Plant Treaty's Governing Body under Article 15 of the treaty, >730,000 accessions of crop, tree, and

Genetic Diversity and Population Structure of Brachiaria Species and Breeding Populations

Crop Science, Volume 57, Issue 5, Page 2633-2644, September–October 2017., 2017
Several apomictic Brachiaria (Trin.) Griseb. (syn. Urochloa P. Beauv.) species are commercially important tropical forage grasses, but little is known about the interspecific diversity and population structure within this genus. Previously published genus‐level Brachiaria phylogenies were conducted with few genotypes and contradicted well‐established ...

Population structure and genetic diversity of Brachiaria grass (Urochloa spp.) accessions from the Democratic Republic of Congo using DArTseq single nucleotide polymorphism markers

Crop Science, Volume 65, Issue 4, July/August 2025.
Abstract Brachiaria grass (Urochloa spp.) is one of the key forage grasses utilized in sub‐Saharan Africa for improving livestock productivity, particularly in terms of milk production and feed sufficiency. Limited information on its genetic resources has hindered its breeding and conservation strategies.

Genetic Diversity and Structure of Ruzigrass Germplasm Collected in Africa and Brazil

Crop Science, Volume 55, Issue 6, Page 2736-2745, November-December 2015., 2015
ABSTRACT Ruzigrass [Urochloa ruziziensis (R. Germain & Evrard) Crins, syn. Brachiaria ruziziensis Germain & Evrard] is a tropical forage native to Africa, first introduced in Brazil in the 1960s. Ruzigrass is diploid, presents sexual reproduction, and is a model species for the generation of genomic resources in the Brachiaria genus. Brachiaria species

High rhizospheric ammonium levels in Sorghum halepense (johnsongrass) suggests nitrification inhibition potential

Agricultural &Environmental Letters, Volume 9, Issue 2, December 2024.
Sorghum halepense (johnsongrass) has the ability to retain high rhizospheric ammonium. This suggests potential nitrification inhibition capability of johnsongrass. Under resource competition on the roadsides, johnsongrass might have undergone adaptive evolution to retain more ammonium than in croplands, which are fertilized periodically with nutrients,
