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...

The phosphorus (P) content of whole roots and root apices has been reported to increase under aluminum (Al) stress, particularly in Al-sensitive plant varieties. We investigated the impact of Al toxicity on the P content of root apices of two tropical forage cultivars of the Brachiaria genus, gro...

Al resistance of signalgrass (Brachiaria decumbens Stapf cv Basilisk), a widely sown tropical forage grass, is outstanding compared with the closely related ruzigrass (Brachiaria ruziziensis Germain and Evrard cv Common) and Al-resistant genotypes of graminaceous crops such as wheat, triticale, a...
