In order to ascertain the reason for low percentage of fruit setting of apricot, the pollen germination of different varieties and fruit branch types was studied. The results showed that there was no remarkable difference in the percentage of pollen germination between different fruit branches of the same variety. But the remarkable difference between different varieties was observed. The percentage of pollen germination of Chetou apricot is highest, 31 7%.Suitable sugar concentration in the culture medium for pollen germination of the varieties is different. The suitable concentration for the most varieties is 10%,but for Badou apricot is 5%.800 thousand international units of penicillin can promote or restrict the pollen germination of different varieties.
