andina colombiana, sin embargo, no se tiene reportes del crecimiento y desarrollo de los frutos de clones importantes como el clon 41 (Quimba) y el clon 8-4. En este estudio se evaluaron los cambios fisicos desde la antesis hasta la madurez fisiologica, mientras que los cambios bioquimicos se evaluaron en la ultima etapa del crecimiento. Los clones 41(Quimba) y 8-4 en las variables: diámetro transversal, diametro longitudinal, peso fresco y peso seco, exhibieron una curva de tipo sigmoidal. Asi mismo, se determino que los frutos de feijoa tienen muy bajos contenidos de almidon. Ademas, utilizando la tecnica de cromatografia liquida de alto desempeño (HPLC), se encontro que los azucares mas abundantes eran fructosa, sacarosa y glucosa. Otras variables medidas fueron los solidos solubles totales (SST), el pH y la acidez total titulable, que se incrementaron gradualmente durante el desarrollo del fruto.</span></p>
