Resumo: A field experiment was carried out at the experimental field of Embrapa Arroz e Feijão with the objective to select representative parameters of the common bean (Phaseolus vulgaris L.) plant growth to be correlated with acid phosphatase activity. The importance of this phosphatase is related with its ability to improve phosphorus up fall under low concentration in acid soil. Five common bean cultivars were tested harvesting plants at weekly interval starting from 7 till 56 days after germination. The enzyme activity in decreasing order was observed in the LM 300030, Carioca, A-176, CNF-10 and Jalo cultivars at l4 day old plants. All the plant parameters analyzed correlated negatively with enzyme activity. Then, the phosphatase activity was considered as a complementary mechanism to the plant to supply its phosphorus needs. The curves of acid phosphatase activity, inorganic and total phosphorus were similar and expressed by second grade equations while both, inorganic and total phosphorus, decreased according to negatively exponential equation modelings. KEY-WORDS: Phosphatase; acid soil; common bean; Phaseolus vulgaris; genotypes.

Um experimento em condições de campo foi realizado no campo experimental da Embrapa Arroz e Feijão, Goiânia (GO), com a finalidade de selecionar parâmetros representativos do desenvolvimento do feijoeiro (Phaseolus vulgaris L.) para serem correlacionados com a atividade da fosfatase ácida. A importância desta fosfatase está relacionada com a sua habilidade de retirar fósforo em condições de baixo teor deste nutriente em solo ácido. Foram testadas cinco cultivares de feijão através do recolhimento semanal de plantas entre 7 e 56 dias após germinação. Os maiores valores da atividade, em ordem decrescente, foram observadas nas cultivares LM 300030, Carioca, A-176, CNF-l0 e Jalo, em plantas com idade entre 7 e 14 dias. Todos os parâmetros de crescimento analisados correlacionaram-se negativamente com a atividade desta enzima. Por isso, a atividade da fosfatase foi considerada um mecanismo complementar que a planta utiliza para suprir suas necessidades em fósforo. As curvas de atividade da fosfatase ácida, fósforo inorgânico e fósforo total foram semelhantes e expressas por equações do segundo grau, enquanto os fósforos, inorgânico e total, decresceram de acordo com o modelo negativo de equações exponenciais.
