Cultivation
Pollinator cultivar — American plum, goose plum
Prunus americana Marsh.
Prunus americana is classified as a partially self-fertile species; however, cross-pollination between different genetic forms is recommended for stable and high productivity.
In the reference 5 varieties crop American plum, where this is mentioned in the description.
Although the American plum is considered a self-fertile species, in practice, agronomists recommend planting several genetically distinct individuals to obtain a stable yield. The high variability of wild Prunus americana forms makes cross-pollination between different seedlings or cultivars an optimal strategy for increasing productivity.
Unlike domesticated species that require strict compatibility schemes, the American plum often acts as an effective universal pollinator for various hybrid and Japanese plums. At the same time, it possesses low compatibility with the European plum (Prunus domestica), which limits its use in interspecific plantings for the pollination of European cultivars.
