The Rootstock Influences Growth and Development Of ‘Deveci’ Pear

The vegetative and reproductive performance of the ‘Deveci’ pear (Pyrus communis L.) grown on three rootstocks [Quince BA 29, EMC (Cydonia oblonga) and a seedling of P. communis] were compared between 2012 and 2013. Vegetative growth characteristics such as the rootstock and trunk diameter, leaf lamina width, leaf lamina length, leaf area, leaf petiole length and thickness, plant height and canopy volume were examined. Phenological characteristics such as the time of first flowering, full flowering, days from full flowering to maturity, harvest date and fruit weight and yield were also investigated. Phenological characteristics were seen in the EMC earlier than in the BA 29 or in the seedling. The most vigorous trees were on the BA 29 followed by the EMC and the seedling. The highest leaf lamina width, length, area and leaf petiole length were obtained from trees on the BA 29 rootstock followed by the EMC and seedling. EMC had a lower leaf petiole thickness than the others. The trees grafted on the BA 29 rootstock had a higher rootstock diameter, trunk diameter, plant height, and plant width and canopy volume than the others. The highest fruit weight and yield per tree were obtained from the trees on the BA 29 (405.7 g and 8.33 kg, respectively) and the EMC (157.6 g and 2.37 kg, respectively) followed by the seedling (62.6 g and 0.69 kg, respectively). As a result of this growing period, we suggest that the ‘Deveci’ pear should be grown on the BA 29 quince rootstock because of the more vigorous growth and the higher yield
