Abstract: In order to study the pollen vigor and germination status of Fragaria vesca, the flower buds at different growth stages were used as materials. Pollen morphology was observed under a microscope, pollen vigor was determined by I-KI staining method, and the germination was carried out on a liquid medium containing boric acid and calcium. The results showed that the pollen morphology, vigor and germination status were different for the small buds, medium buds, large buds (which were not flowering), blossoming and blooming periods. The pollen in the big bud anthers was mostly large and round, with full peripheral shape, yellow-orange, high pollen vigor, high germination rate, and long pollen tube length. In the small bud and medium bud periods before the large bud period, the blossoming and blooming periods afterwards, the pollen was small, the surrounding shape was irregular, the pollen vigor was not high, germination rate was also very low, and the pollen tube was short. It indicates that the large bud stage of Fragaria vesca is the period with the highest pollen vigor and germination rate, which is suitable for hybrid pollination or storage.

Key words: pollen vitality, pollen germination, Fragaria vesca
