Abstract
Low fruiting is the main problem related to the pear production in Brazil, which makes the country one of the major pear importers. This research aimed to evaluate different rootstocks to pear tree cultivar 'Carrick' to be used in commercial orchards. The experiment was carried out in Pelotas/RS, located at latitude 31°52'00S, longitude 52°21'24W Greenwich and altitude of 13.24 m. The orchard was set up in 2002 with a density of 2000 trees.ha -1 . The trees were conducted in slender spindler system trained on three-wire support with a dripping irrigation system. The treatments assessed were 13 quince rootstocks (Cydonia oblonga) cultivars 'Adams', 'Alaranjado', 'BA 29', 'Bereczcki', 'Champion', 'Du Lot', 'D'Vranja', 'EMC', 'Inta 267', 'Lageado', 'Melliforme', 'PineApple' and 'Portugal' and one Pyrus calleryana. The experimental design utilized was a complete randomized block with 3 replications of 5 trees each. The variables assessed were rootstock/scion trunk diameter, tree height, canopy volume, pruning weight, productivity and productivity efficiency. 'D'Vranja' rootstock provided the highest vigor to the tree, whereas the rootstock cultivars 'Du Lot', 'Lageado' and 'Bereczcki' the lesser vigor, however not differing from most of the rootstocks in the study. The highest productivity was verified by using the rootstock 'Portugal' (1.12 t.ha -1 ), followed by 'EMC' that did not differ from 'D'Vranja' and 'BA 29'. 'D'Vranja' showed the highest vigor and also had the highest productivity efficiency (9.53), but did not differ from 'BA 29'. Although 'D'Vranja' provided more vigor to the tree, it is still a good rootstock alternative to the pear cultivar 'Carrick'.
