Sažetak
The olive orchard productivity largely depends on the choice of planted cultivars and their pollination needs. The self-incompatibility has been widely reported in olive, and the cross-pollination usually enhances fertilization, fruit set and yield. The efficiency of fertilization and fruit set relies on compatibility between recipient and pollen donor trees. Different methods have been employed to study compatibility relationships between olive cultivars and to obtain reliable results on compatible and incompatible combinations. The fruit set has been the established method used to test cross-compatibility in this species but the assessment of compatibility relaying on pollen performance in vivo is insufficiently examined. With the aim to determine pollen germination, pollen tube growth and fertilization percentage in flowers of different olive cultivars (‘Lastovka’, ‘Leccino’, ‘Levantinka’ and ‘Oblica’), the self-pollination and cross-pollination treatments were performed. Flowers were cross-pollinated with pollen of various pollen donor cultivars. The self-pollination treatment was also applied pollinating the flowers with their own pollen. Pollen performance in the pistil was assessed using fluorescence microscopy. Pollen tube growth and fertilization percentage depended on the genotype of pollen donor. The percentages of fertilization were significantly higher in cross-pollinated flowers than in self-pollinated flowers.
