Methods for overcoming dormancy in Brachiaria brizantha seeds

Australian Journal of Crop Science, 2021
Brachiaria brizantha is a forage species widely used in Brazilian pastures and its seeds have contamination in several areas of countries. Its high germination is fundamental in pasture formation. However, it is common for seeds of this species to have natural dormancy, negatively influencing pasture formation, resulting in losses to the producer. Thus,

Amélioration des pâturages. Le Brachiaria brizantha

Revue d’élevage et de médecine vétérinaire des pays tropicaux, 1966
Le Brachiaria brizantha est cultivé dans des zones écologiquement très différentes. Dans chacune de ces zones, ses qualités de rusticité, d'adaptation à la sécheresse, et ses facultés de propagation en font une espèce fourragère particulièrement adaptée à la diffusion du pâturage artificiel en milieu rural.

Microsporogenesis in Brachiaria brizantha (Poaceae) as a selection tool for breeding

Genetics and Molecular Research, 2012
The genus Brachiaria comprises more than 100 species and is the single most important genus of forage grass in the tropics. Brachiaria brizantha, widely used in Brazilian pastures for beef and dairy production, is native to tropical Africa. As a subsidy to the breeding program underway in Brazil, cytological studies were employed to determine the ...
