Cultivation
Pollinator cultivar — Sour cherry
Prunus cerasus L.
Most sour cherry cultivars are self-incompatible and require pollinators for cross-pollination. Selecting compatible pairs is limited by frequent cross-incompatibility and the necessity for flowering periods to overlap.
In the reference 68 varieties crop Sour cherry, where this is mentioned in the description.
Sour cherries are categorized into self-incompatible, partially self-compatible, and self-compatible cultivars. Self-incompatible forms rely entirely on pollen from other cultivars, whereas self-compatible ones can set about 50% of their fruit autonomously, although their yields significantly increase with cross-pollination.
A critical factor for this crop is cross-incompatibility, where cultivars are unable to pollinate each other even when blooming simultaneously. It is also important to note that the degree of self-compatibility for the same cultivar may vary depending on the climatic conditions of the growing region.
Interaction between sour cherry and other stone fruits is limited: sweet cherry can serve as a pollinator for sour cherry when flowering phases coincide, whereas the reverse pollination is difficult. Successful fruit set on flower spurs requires the mandatory synchronization of phenological flowering phases between the chosen pollinator cultivars.
