The field of pomology, or fruit science, has undergone a radical transformation from traditional orchard management to a high-precision, science-driven discipline. At the heart of this academic and practical evolution in the Spanish-speaking world is the seminal work Fruticultura Manuel Agustí Fonfría
Fruticultura by Manuel Agustí is a definitive technical manual covering the physiology and cultivation of fruit trees, primarily focusing on temperate species with extensions into tropical agronomy.
Beyond mere size, Agustí dedicates substantial analysis to the qualitative parameters of fruit: sugar content (Brix), acidity, and firmness. He argues that maturity is not simply the end of growth but a distinct physiological process involving the breakdown of complex structures and the accumulation of specific metabolites.
