RESUMEN Se present an trazas evolutivas para galaxias de disco en el marco de un regimen de formaci6n estelar estacionaria. Se comparan estas trazas con las propiedades integrales observadas de galaxias compiladas de la literatura. La comparaci6n involucra fundamentalmente la historia de la formaci6n estelar de las galaxias. Se obtiene una concordancia razonable en los casos de las correlaciones de tres parametros luminosidad en el azul vs. masa de gas vs. densidad superficial y densidad superficial de gas vs. indice de color B-V vs. brillo en el azul. ABSTRACT Evolutionary tracks for disk galaxies are presented in the frame of a stationary star formation (SF) regime. These tracks are compared with the integral observed features for a sample of galaxies compiled from the literature. The tests carried out involve basically the SF history of the galaxy. We obtain a reasonable agreement in the cases of the three parameter correlations: blue luminosity vs. gas mass vs. surface density and surface gas density vs. B-V color index vs. B brightness. Key words: GALAXIES: EVOLUTION
