Self-compatibility in 18 European plum cultivars were examined using the method of fluorescence microscopy. According to self-compatibility, the cultivars were divided into two groups: self-compatible and self-incompatible. In self-compatible cultivars the number of pistils, where pollen tubes reached the base of the style varied from 32.00% (Anna Spaeth) to 91.18% (Wangenheims Fruehzwetsche). Mean number of pollen tubes at the base of style in these cultivars ranged from 0.52 to 3.97. Cultivars were considered self-incompatible if pollen tubes stopped their growth in the style along with forming characteristic swellings at their tips. Of the studied cultivars, 13 were found to be self-compatible, while 5 were found to be self-incompatible.
