A: The kiwifruit commercial pollen must be used with it. Mix it according to the amount of flowers and how much it is mixed with. If storage is required, the pollen can be stored in a clean glass bottle (cannot be stored in metal containers) and stored in a low-temperature and dry place. The pure pollen can be stored in a sealed container at -20°C for 1 to 2 years at 5°C. It can be stored for about 10 days. The percentage of fruit set in pollination stored under dry room temperature for 5 days can reach 100%, but as the storage time prolongs, the quality of fruit after pollination will gradually decrease, and it will be stored for 24 hours to 48 hours under normal room temperature storage conditions. Pollen pollination works best. KOKEN Co., Ltd , https://www.hnb-maker.com
