EFEITO DA TEMPERATURA DA ÁGUA NA QUEBRA DE DORMÊNCIA DE SEMENTES DE Canavalia brasiliensis

INFORME ECONÔMICO (UFPI), 2020
O Canavalia brasiliensis (feijão bravo-do-ceará) é uma leguminosa anual ou bianual que apresenta grande potencial de produção de biomassa e rusticidade durante períodos de deficiência hídrica, devido ao sistema radicular profundo, que absorve água e nutrientes em maiores profundidades do solo.

Lectin from Canavalia brasiliensis (ConBr) protects hippocampal slices against glutamate neurotoxicity in a manner dependent of PI3K/Akt pathway

Neurochemistry International, 2013
The excitotoxicity induced by excessive activation of the glutamatergic neurotransmission pathway is involved in several neuropathologies. In this sense, molecules that prevent the release of glutamate or the excessive activation of its receptors can be useful in preventing the neuronal cell death observed in these diseases.

Farm-Scale Tradeoffs Between Legume Use as Forage versus Green Manure: The Case ofCanavalia brasiliensis

Agroecology and Sustainable Food Systems, 2013
To support a sustainable increase in agricultural productivity, the multipurpose legume Canavalia brasiliensis was integrated as forage and green manure into the smallholder crop-livestock system of the Nicaraguan hillsides. Through on-farm trials, surveys, and on-station experiments, we investigated the biophysical and socioeconomic tradeoffs in ...
