Abstract
Budding height effect on sweet cherry (Prunus avium L.) growth was investigated using several rootstocks.
In 1997, a nursery trial was set up that included Burlat, Summit and Van sweet cherries budded onto Edabriz, Gisela 5 and Maxma 14 rootstocks at 10, 20 and 30 cm above soil level and onto Cab 11E and Mazzard (P. avium) seedlings at 10, 30 and 60 cm above soil level.
With those trees, an orchard trial was established in 1999 in three locations of north-eastern Portugal.
Trunk diameter was recorded at the 6th leaf (2003), and trunk cross-sectional area (TCSA) was calculated.
Cherry tree growth varied with rootstock and budding level, but no significant differences were observed between cultivars.
TCSA reduction on Edabriz, Gisela 5 and Maxma 14 was 28, 25 and 19%, respectively, when comparing budding at 10 and 30 cm.
There was a reduction of 22% in the trees on Cab 11E, but only 5% on Mazzard, when comparing budding at 10 and 60 cm.
Thus, by the 6th year, higher budding height decreased tree vigour in all locations and rootstocks, except Cab 11E, for which budding at 30 cm rather than 60 cm had a greater TCSA reduction (26%). Thus, budding height can contribute to control of tree cherry growth, helping to manage canopy size and crop accessibility.
