Assim sendo, o objetivo do trabalho foi caracterizar a distribuição do sistema radicular ao longo do perfil do solo das diferentes combinações de cultivares de pereiras europeias sobre porta-enxertos de marmeleiro em sistemas de média densidade (2.500 plantas ha-1). Informações sobre desenvolvimento das raízes constituem ferramenta essencial capaz de identificar, dentre as plantas de uma espécie, a que tenha maior capacidade de potencializar características de crescimento e desenvolvimento em sua parte aérea. It was observed that the average of six combinations, 86% of root growth in the horizontal distance is located up to 80 cm. For the effective distance, it was observed that 80% of the total root length is distributed in up to 80 cm for all combinations, except for Clapp’s Favourite/EMA, whose actual distance was 100 cm. In relation to effective depth, it was observed that up to 40 cm deep, 80% of the total root length and 83% of root concentration were found for all combinations. The combinations evaluated were: Abbè Fetel/Adams, Clapp´s Favourite/EMA, Santa Maria/Adams, Rocha/Adams, Decana du Comice/Adams, Packham´s Triumph/EMA, Packham´s Triumph/Adams and Conference/ Adams. The aim of this study was to characterize the distribution of the root system throughout the soil profile of different European pear cultivars and quince rootstock combinations on medium plant density systems (2500 plants ha-1). Information on root development is an essential tool capable of identifying, among plants of a species, the one that has the greatest capacity to potentiate growth and development characteristics in its aerial part.
