Conteúdo: 	The reationship between acid phosphatase activity (APA) and phosphorus(P) stress in two bean genotypes (Phaseolus vulgaris var Tacarigua andvar Manuare) and in cowpea (Vigna unguiculata var TUY) are reported inthis paper. A highter APA was found in young as compared to mature leaves, and the expression of APA also showed intraspecific variation. Acid phosphatase activity was related to the age of the leaves and was easily measured in leaf discs, specially for bean. This and the ratio of P concentration between young and mature leaves may be an alternative to absolute P-status determination in plants.
