Abstract
The influence of the peach-almond hybrid rootstocks GF 677 and Garnem on the growth and reproductive characteristics were studied in combination with the peach cultivars ‘Redhaven’, ‘UFO 4’ and nectarine cultivar ‘Big Top’. The experimental orchard was planted at the density of 571 trees ha‑1 (5.0×3.5 m) in the spring of 2014 and trees were formed as peach free growing crown.
The poorly known in Bulgaria peach-almond hybrid rootstock Garnem induced significantly higher growth, expressed in a larger trunk-cross section area and crown volume in all three cultivars.
The trees on rootstock Garnem had significantly lower indexes of productivity in comparison with those of commonly grown GF 677 in combination with the three cultivars included in the study.
Both rootstocks do not induce significant differences in terms of fruit weight.
