Aluminum‐resistant Brachiaria decumbens Stapf cv. Basilisk (signalgrass) and closely related, but less resistant Brachiaria ruziziensis Germain & Evrard cv. Common (ruzigrass) both accumulated high concentrations of aluminum (Al) in roots. Approximately two thirds of the total Al was complexed by...

Se evaluaron en invernadero en un suelo de Matazul, Meta, Colombia durante 6 semanas, 2 genotipos de Brachiaria (uno mejor adaptado a bajo P, B. decumbens y otro menos adaptado, B. ruziziensis) y 8 progenies del cruzamiento entre ellos ( mejores adaptados: H-7, H-40, H-28, H-58; menos adaptados: ...

Phosphorus (P) deficiency and aluminium (Al) toxicity are widespread in Oxisols of the tropical savannas of eastern Colombia. A field experiment was conducted to determine the effect of Al toxicity and P deficiency on plant growth and nutrient uptake of two Brachiaria species. To examine the infl...
