| Abstract:
A research plot was planted at the Érd-Elvira research farm at the Research Institute for Fruitgrowing and Ornamentals, Budapest, in spring 1997 with the aim testing rootstocks and investigating scion/rootstock interactions. Seven dwarfing rootstocks (‘Weiroot 13’, ‘Weiroot 53’, ‘Weiroot 72’, ‘Weiroot 154’, ‘Weiroot 158’, ‘GiSelA 5’, ‘P-HL-A’), one Hungarian selected Mazzard seedling Cerasus avium ‘C. 2493’ and Cerasus mahaleb ‘Cema’ seedling as a control were combined with 3 sweet cherries (‘Germersdorfi 3’, ‘Linda’, ‘Katalin’) and one sour cherry variety (‘IV-2/152 (Piramis)’). The dwarfing effect of the rootstocks on the sweet and sour cherry varieties was different. However, the greatest vigour was induced by ‘Cema’,followed by Cerasus avium ‘C. 2493’, ‘Weiroot 13’, ‘P-HL-A’, ‘Weiroot 158’, ‘Weiroot 154’, ‘Weiroot 72’, ‘Weiroot 53’, and ‘GiSelA 5’. When observing reproductive traits, the most remarkable effects were on bloomtime, fruit yield and fruit size. Compared to the trees on Cerasus mahaleb ‘Cema’, yields of all other sweet cherry combinations were higher except those on the seedling and on ‘P-HL-A’ rootstocks. The highest cumulative yield efficiency was produced on ‘GiSelA 5’ but trees on this rootstock showed some negative features (early bloom time, tendency to overcrop and barewood formation), which might be caused by site and our climatic conditions. ‘Weiroot 158’ produced the healthiest trees among the rootstocks tested. Among the sour cherry trees, those on Cerasus mahaleb ‘Cema’ and on ‘Weiroot 13’ produced the highest yield. The largest fruit size was produced on trees grafted on ‘Weiroot 72’; 28% of the fruit were larger than 26 mm diameter. | |
