EVALUATION OF ROOTSTOCKS FOR CHERRY TREES

In 1989, two experimental orchards were established at the Jerte Valley in Spain, studying the performance of the scion cultivars Burlat and Hedelfingen grafted on five rootstocks.
Trees were placed in a complete randomized block design with six single-tree replications for each rootstock-scion combination.
Trees were spaced at 5 x 5 m, and trained to the vase tree form. ‘Burlat’ scions were grafted and evaluated on four rootstocks: Colt (P. avium x P. pseudocerasus), SL-64 (P. mahaleb), Reboldo (P. avium) and Stockton Morello (SM) (P. cerasus). In 1996, the SM rootstock had the highest cumulative yield for all rootstocks, whereas SL-64 had the lowest one.
Trees on Reboldo were the most vigorous, while trees on SM were the smallest ones.
Yield efficiency, measured as kg of fruit/cm² of trunk cross-sectional area (TCSA) has been calculated; SM was the best rootstock and there were no significant differences among the other rootstocks.
Mean fruit weight ranged from 7.68 g on SL-64 to 7.44 g on SM. Trees on SM and SL-64 bloomed and ripened earlier than trees on Colt and Reboldo.

‘Hedelfingen’ scions were grafted and studied on four rootstocks: Colt, SL-64, Reboldo and Masto de Montañana (MM) (P. cerasus). The MM rootstock had a significant higher cumulative yield than the others ones, whereas Reboldo had the lowest productivity.
Trees on Colt were the most vigorous, while trees on MM were the least vigorous.
MM had the highest yield efficiency, whereas Reboldo had the lowest.
Mean fruit weight ranged from 7.86 g on Colt to 6.26 g on MM.
