Sažetak
'Tugarka' is most presented cultivar grown in orchards of Mediterranean part of Croatia. Inadequate pollination caused irregular yield of that valuable cultivar. The aim of this study was to determinate the success of self-pollination, cross-pollination and free-pollination of 'Tugarka', and to define its best pollenizer(s). Cultivars used as pollen donors ('Lambert compact', 'Bing spur', 'Van compact', and sour cherry 'Marasca poljička') were selected according to their simultaneous flowering period with “Tugarka”. Pollen germination success of tested cultivars was determined in 12% sucrose solution at 22ºC using hanging drop technique. During the full bloom pollen of each pollenizer was applied to isolated branches of acceptor cultivar. Branches aimed to free-pollination were not isolated. Fruit set following self-pollination, cross-pollination and free-pollination was analysed just before the harvest. Pollen germination rates varied from 35% (Van compact) to 41.04% (Bing spur). Absence of fruit set following self-pollination described 'Tugarka' as self-incompatible cultivar. Significantly the best fruit set of 'Tugarka' was recorded after pollination with 'Lambert compact' (22.5%), and the lowest following pollination with sour cherry 'Poljička' (14.2%).
