Adubação nitrogenada em híbridos de Brachiaria spp.

open access: diamondOBSERVATÓRIO DE LA ECONOMÍA LATINOAMERICANA
As exigências nutricionais dos híbridos de Brachiaria spp. ainda são pouco conhecidas, uma vez que, durante o processo de melhoramento genético, são utilizadas espécies com diferentes demandas nutricionais. Assim, o objetivo deste estudo foi verificar se os híbridos de Brachiaria apresentam variações quanto à exigência de nitrogênio e identificar quais

Characterizing herbivore resistance mechanisms: spittlebugs on Brachiaria spp. as an example. [PDF]

open access: yesJ Vis Exp, 2011
Plants can resist herbivore damage through three broad mechanisms: antixenosis, antibiosis and tolerance(1). Antixenosis is the degree to which the plant is avoided when the herbivore is able to select other plants(2). Antibiosis is the degree to which the plant affects the fitness of the herbivore feeding on it(1).Tolerance is the degree to which the ...

Toward in vitro fertilization in Brachiaria spp. [PDF]

open access: yesSexual Plant Reproduction, 2010
Brachiaria are forage grasses widely cultivated in tropical areas. In vitro pollination was applied to accessions of Brachiaria spp. by placing pollen of non-dehiscent anthers on a solid medium near isolated ovaries. Viability and in vitro germination were tested in order to establish good conditions for pollen development.

Characterization of Resistance to Adult Spittlebugs (Hemiptera: Cercopidae) in <I>Brachiaria</I> spp. [PDF]

open access: bronzeJournal of economic entomology, 2013
Nymphs and adults of several spittlebug (Hemiptera: Cercopidae) species are key pests of forage brachiariagrasses (Brachiaria spp.) in tropical America. To support current breeding programs, a series of experiments aimed at characterizing the mechanisms of resistance to adult feeding damage were carried out.

Chronic liver disease in cattle associated with ingestion of Brachiaria spp. [PDF]

open access: yesCiência Rural, 2016
ABSTRACT: One hundred and ninety livers condemned due to chronic disease (fibrosis) were evaluated in a bovine slaughterhouse over 12 months. Hepatic lymph nodes were also examined while still attached to livers. The major macroscopic lesion observed in the livers was moderate to severe atrophy of the left lobe associated with compensatory hypertrophy ...
