Abstract: The vitality, moisture and room temperature lifetime of 20 Spathiphyllum floribundum fresh pollen were determined, and vitality changes of these 20 Spathiphyllum floribundum pollen at cryopreservation in 2 years were studied. The results showed that: the rang of 20 Spathiphyllum floribundum pollen germination rate was about 28%-59%, varieties of fresh pollen vitality differences greatly. Testing each fresh pollen varieties of Spathiphyllum floribundum, the rang of these moisture content was about 10%-13%. The fresh pollen lifetime of Spathiphyllum Kochii varieties was not exceeding 15 days. To the same Spathiphyllum floribundum varieties, cryopreservation time would make the Spathiphyllum floribundum pollen vitality changes at some extent; in cryopreservation of 2 years, all tested Spathiphyllum floribundum pollen were not vitality loss, part of the pollen vitality improved significantly, described that cryopreservation as an germplasm resources long-term preservation for Spathiphyllum floribundum pollen was an effective method.
