Taking five sweet cherry cultivars in the west-northern part of Hebei as materials,the pollen viability of five varieties were tested by triphenyl tetrazolium chloride (TTC) method,in solar greenhouse,choosing varieties with strong pollen viability as pollination varieties,pollen germination and pollen tube growth in the styles of two sweet cherry cultivars,‘Hongdeng’ and ‘Lapins’ were examined by utilizing fluorescence micro-technology.The results showed that the pollen viability of ‘Lapins’ was the highest,being 71.05%;followed was ‘Hongyan’,being 52.83%;the next was ‘Hongdeng’,its pollen viability was 45.21%;the pollen viability of ‘Zaodaguo’ and ‘Xianfeng’ were the lowest,and the difference was not significant,being 33.09% and 30.20%.So ‘Lapins’ and ‘Hongyan’ could be used as ideal pollination varieties,‘Lapins’ could be used as pollinator for Hongdeng,‘Hongyan’ could be used as pollinator for ‘Lapins’.In the solar greenhouse,most pollens of ‘Hongdeng’ germinated after 6 h of pollination,and the pollens of ‘Lapins’ germinated after 8 h of pollination,but the pollen tubes of two sweet cherry cultivars entered the ovary at 96 h after pollination.
