Abstract: The methods to test pollen viability and to store the pollen of taro were studied in order to ensure taro crossbreeding experiment. The results showed that both stigma dilution culture method and medium culture method could be used to test the pollen viability of taro, and the best medium of pollen germination was 10 mg/L boric acid 0.01% calcium chloride anhydrous 5% sucrose. Taro pollen had short life, but different varieties of taro had different pollen lifetimes. Pollen could be stored longer in the 15% air humidity and -20℃ under drying.
