| Abstract:
The influence of Gisela® 5 rootstock on the growth, yield and fruit quality of 'Burlat', 'Vega', 'NY 9801' and 'Kordia' sweet cherry was investigated. The same cultivars grafted on Mazzard seedlings (P. avium L.) were used as controls. The field experiment was carried out on grey-brown podzolic soil at the Experimental Station in Dabrowice (Central Poland) from 1995 to 2000. In the orchards, a drip irrigation system was installed for applying water during the vegetation season. Compared to Mazzard, Gisela® 5 reduced significantly sweet cherry tree growth. Depending on the cultivar, trunk cross-sectional areas of six-year-old trees grafted on Gisela® 5 were from 18 to 33% smaller than those on Mazzard. Cumulative yields and yield efficiencies for all of the cultivars on Gisela® 5 were higher than for the control trees. However, fruit from trees on Mazzard were larger for all cultivars than on Gisela® 5. Fruit soluble solids were not affected by rootstocks. | |
