Actinidia arguta is distributed in the mountainous areas in Korea and has well adapted to the climate with high resistance to coldness and pests. A. arguta has an edible smooth skin and containing high amounts of nectar and pollen with mild flavors satisfy the good honey plant. Optimal condition for pollen germination was suggested as a basic research of flowering physiology in order to identify the characteristics of flowering and seed setting of A. arguta. Pollen samples were collected during flowering season from the May to the June. From the study, we found that the flowering time and pollen amount of each 9 clones were different. Also, pollen germination were significantly different among the levels of germination temperature and time. In this study, the interactive effects were also observed between germination time and temperature. Pollen germination was examined in 9 clones and found that there was little different with germination time. Pollen germination was high when the pollen cultured at 25Celsius (71.67%) for 24 hours.
