Influences of Storage Temperatures on Activated Pollen Ratio in Ginkgo biloba

WANG Yan,ZHANG Li ming (Department of Horticulture, Hubei Agricultural College,Jingzhou,Hubei 434025,China)  
The influences of different storage temperatures on activated pollen ratio in Ginkgo biloba L were studied in 2000. The results indicated that activated pollen ratio was 92.9%~98.2% at the moment when the pollen were just collected, and then decreased under the 3 different treatments. However, there were very significant differences among 3 kinds of treatments(Treatment I: storage at normal temperature; Treatment Ⅱ: storage at 2~5 ℃; Treatment III: storage at -5~-10 ℃).Of all treatments, treatment Ⅱ had the best effect, i.e.: the activated pollen ratio was the highest, and still reached 65% after 14 days the pollens were stored, which could meet cultivation demand.
