Calidad de frutos y maduración en naranjo dulce ‘Valencia Late’ [Citrus sinensis (L) Osbeck] cv Limeira, sobre diferentes portainjertos M. D. CHABBAL L. I. GIMÉNEZ S. M. MAZZA M. D. J. RAMIREZ V. A. RODRÍGUEZ Agrociencias calidad Cítricos análisis multivariante Para responder a las exigencias de los mercados mundiales es necesario la búsqueda permanente de portainjertos que confieran calidad a los frutos y maduración anticipada. El objetivo de este trabajo fue caracterizar plantas de naranjo dulce ‘Valencia late’ injertadas sobre 17 portainjertos, según atributos de calidad de frutos y precocidad de la maduración e identificar grupos de similares características. En un diseño completamente aleatorizado con seis repeticiones, se probaron combinaciones de naranjo dulce ‘Valencia late’ con 17 portainjertos. Al momento de la cosecha se seleccionaron al azar 15 frutos y se determinaron las siguientes variables: DE, GC, PJ, SST y ATT %, también se calculó el IM. Mediante un análisis de componentes principales, gráfico biplot y análisis de la varianza multivariado se pudieron agrupar los 17 portainjertos estudiados en cuatro grupos de acuerdo con la anticipación en la maduración. El grupo que más anticipa la cosecha se caracterizó por tener frutos con altos IM y contenidos de SST y menor ATT %; el segundo presenta frutos con altos PJ y contenidos de SST y, pero también alta ATT %; el tercero contiene los frutos con los mayores GC, los menores valores de PJ, SST, ATT % y valores intermedios para IM y DE; el grupo de menor anticipación se caracterizó por frutos con mayor ATT %, menores valores de IM y DE y valores intermedios de las otras variables. 2019 artículo científico 0325-8718 https://www.redalyc.org/articulo.oa?id=86458941006 https://www.redalyc.org/journal/864/86458941006/ https://www.redalyc.org/journal/864/86458941006/html/ https://www.redalyc.org/journal/864/86458941006/86458941006.epub https://www.redalyc.org/journal/864/86458941006/movil es http://www.redalyc.org/revista.oa?id=864 RIA.
