Self-compatibility in 25 apricot cultivars of European ecogeographical group was studied. Flowers were pollinated under laboratory conditions and than the growth of pollen tubers in the styles of pistils was observed by means of fluorescence microscopy. In self-compatible cultivars almost in all pistils (95-100%) at least one pollen tube reached the ovary, and frequently the ovule (33-94%). In self-incompatible cultivars pollen tubes ceased growth in the style by forming plugs due to callose accumulation. In these cultivars pollen tubes very rarely (0-14%) reached the ovary, whereas they were not found in the ovules. Out of all tested cultivars, 16 were found to be self-compatible.
