In this work there were established that the native populations of tomato present different characteristics of quality (internal and external) in relation with the commercial varieties. Likewise, the pattern of maturity of the native populations is different from that of commercial varieties and that the native populations are better accepted by the consumers. The fruits were evaluated in three states of maturity, deciding the variables of response; acidity titulable, total soluble solids, pH, vitamin C, firmness, color, concentration of CO2 and ethylene, days postharvest and acceptability. The design was completely at random with arrangement factorial and for the acceptability a design of blocks at random. Both the chemical composition and the external factors evolve as it advances the maturity of the fruit, diminishing the firmness and the life postharvest, and increasing the total soluble solids, pH, acidity, the production of CO2 and ethylene. The native populations present excellent characteristics of quality in such a way that they can compete with commercial varieties.PATRONES DE MADURACION POSTCOSECHA EN POBLACIONES220117s xx 000 0 und d a185959 aDisponible en PDF aFruit maturity9156724 aMaduración de las fruras 9160824 aTomatesxTecnología postcosecha 9160825 aTomatoesxPostharvest technology 9160826 aGarcía Osorio, Cecilia, asesor9163763 aMena Nevarez, Gustavo, asesor 91637641 aValle Guadarrama, Salvador9151202 cTESIS C65 2009 c185959d185959
