Variety traits
Pyrus communis L.
A biological parameter of the pear tree that determines tree dimensions and shoot formation intensity, used for orchard design and cultivar breeding.
In the reference 325 varieties crop European pear, where this is mentioned in the description.
To assess pear vigor, measurements of tree height, crown diameter, annual shoot length, and trunk cross-sectional area are employed. These indicators allow for the classification of cultivars into vigorous types, which require larger feeding areas, and dwarfing or semi-dwarfing types, which are suitable for high-density intensive plantings.
Pear vigor is closely related to cultivation technology, determining planting schemes, training methods, and pruning frequency. Dwarfing forms often exhibit increased specific productivity and earlier entry into fruiting compared to vigorous cultivars, which require significant expenditures for crown growth control.
