Sažetak
Pollen performance under in vitro conditions is related to its ability to set seeds and fruits following in vivo pollination. Two in vitro tests usually used for pollen viability and germination capacity evaluation were compared in this study. Pollen performance of six sweet cherry cultivars ('Bing', 'Gomilička', 'Hedelfinger', 'Lambert', 'Stonska' and 'Tugarka') was tested using in vitro pollen germination test and fluorochromatic reaction test (FCR). Pollen germination success tested on germination medium consisted of 15% sucrose + 1% agar after 24h of incubation ranged from 22.4% ('Tugarka') to 61.4% ('Hedelfinger'). The highest germinations among the tested cultivars were recorded for 'Hedelfinger' after 2h and 24h. Significant differences among the pollen viability and germination success were recorded for all tested cultivars except for 'Hedelfinger'. Higher pollen viability was found with FCR for 'Tugarka' (83.8%) and Bing (82.6%) compared to 'Gomilička' (71.7%), 'Lambert' (69.9%), 'Hedelfinger' (69.3%), and 'Stonska' (64.6%). Pollen germination test showed lower viability of tested pollen than FCR.
