Methodology for evaluating the vigor of cherries genotypes in the garden

Abstract

The methodology for assessing the vigor of the cherry and sweet cherry genotypes in the garden, the crown volume, the crown projection area and the cross-sectional area of the stem were used. For each vigor group, specific indicators of these characteristics were defined. It was recommended to use the methods when studying growth processes of varieties and selection of genotypes with different vigor and recommended optimal planting schemes for them, in which their genetic potential would be most fully realized. In accordance with the vigor group, it was recommended to use the scheme of planting in the garden: for very dwarf forms – 4 × 1.5 m, for dwarf – 4 × 1.5–2 m, for semi-dwarf – 4 × 2–2.5 m, for semivigorous – 4–5 × 2.5–3 m, for vigorous ones – 4–5 × 3–3.5 m.
