The experiment was conducted to determine pollen morphology of Chinese peony and its germination. The results were obtained as following ; Pollen shpae was usually large ellipse and the pol­len germination rate of Eui-seong Peony line was 71% which was lower than that of other Peony lines. In a bud, the pollen began to be observed on $7{\sim}9days$ before flowering and as getting on for flowering time, normal pollen and germination rates were higher. The pollen germination and elongation beganat 30 minutes after incubation on artificial medium and were completed after $2{\sim}3\;hours$. As the storage time went on, the pollen life span was shortened. The germination rate was 51% at 8 days-storage of room temperature. The germination rate was 48% ad 43% at 95 day-storage in $0^{\circ}C$ and $-15^{\circ}C$, respectively.
