Conteúdo: 	It was found in the germination test of citrus pollen that the optimum sucrose concentration of artificial medium was about 20 percent, and optimum germination temperature was 25 °C. Pollen stored at 5 °C in relative humidity of 20 percent or 30 percent remained viable for three years. Pollen stored at -20 °C maintained high viability for three years. No differences were found between the pollen stored for three years at -20 °C and the one freshly collected in fruit set and seed numer per fruit. The viability of freeze-dried pollen was not reduced after one year of storage at -20 °C. Pollen storage in liquid nitrogen maintained high viability for two years. When pollen was stored in various organic solvents, it remained viable for four months, but eventually lost its germinability after seven months of storage.
