Sažetak
Simultaneous flowering of olive cultivars enables effective pollination, fertilization, and fruit set if compatibility between recipient and polleniser trees exists. In the olive orchards we usually find cultivars with different flowering periods. Under those conditions, the fruit set of cultivars with a short effective pollination period (EPP) may be endangered. EPP integrates the duration of stigma receptivity, pollen tube growth kinetics, and ovule viability. The main objectives were to study the components of the EPP in Croatian olive cultivar Lastovka, than calculate the duration of the EPP, and elucidate the importance of each component in losses of productivity. Better pollen performance was recorded in cross-pollinated flowers than in flowers pollinated with its own pollen. The difference was already apparent at 48h after pollination, when pollen tube(s) was found in 27% of cross-pollinated flowers, while at the same time fertilization was observed in 9.5% of self-pollinated flowers. Stigma receptivity and ovule viability did not endanger duration of the EPP in ‘Lastovka’. Longer duration of the EPP was recorded from analyses of its components than from the fruit set declines resulting from sequential pollination in the orchard. Those results indicate that self- or cross- incompatibility may be more important factor than a short EPP in limiting fruit set in ‘Lastovka’.
