| Abstract:
Pyrus communis is the main pear rootstock in Argentina, due to the lack of compatibility of quince with the main cultivars (Bartlett, Beurré d'Anjou and Packham's Triumph). In order to overcame this limitation, and permit high density orchards, since 1991 studies are conducted on quince MA/Bartlett and Beurré d'Anjou, utilizing interstocks of the selections OH x F # 51, 69 and 333, with Pyrus communis as check. Results show that during the first five years there was a reduced vegetative growth and increased precocity on the trees grafted on quince. Incompatibility problems were not detected up to now. | |
