Resumos

Foi estudada a absorção de fosfato marcado com 32P por raizes destacadas de três variedades de sorgo granífero. A influência do tempo, concentração iônica externa, pH, aeração, venenos respiratórios e desacopladores de fosforilação oxidativa foi considerada; o estudo da cinéstica da absorção mostrou diferenças entre as variedades nos parâmetros michaelianos.

Experiments were carried out in order to study the effect of time external concentration, pH, temperature, aeration and inhibitors (KF, KCN and 2,4-DNP) on the phosphate absorption by the excised roots of grain Sorghum bicolor L. Moench var. Contibrasil 102, DeKalb and Tey-101, using 32P as tracer.

RESUMO

Foi estudada a absorção de fosfato marcado com ³²P por raizes destacadas de três variedades de sorgo granífero. A influência do tempo, concentração iônica externa, pH, aeração, venenos respiratórios e desacopladores de fosforilação oxidativa foi considerada; o estudo da cinéstica da absorção mostrou diferenças entre as variedades nos parâmetros michaelianos.

SUMMARY

Experiments were carried out in order to study the effect of time external concentration, pH, temperature, aeration and inhibitors (KF, KCN and 2,4-DNP) on the phosphate absorption by the excised roots of grain Sorghum bicolor L. Moench var. Contibrasil 102, DeKalb and Tey-101, using ³²P as tracer.
