By means of MTT staining method, pollen viability of Pinus dabeshanensis C. Y. Cheng et Y. W. Law stored for 1-170 d under conditions of room temperature (20℃-28℃), 4℃and -20℃was measured. The result shows that pollen viability of P. dabeshanensis is 95. 97% during pollen flourishing period. When storage for 7 d at different temperatures, pollen viability is still over 90%. Pollen viability decreases to 40. 33% when storage for 75 d at room temperature, while that decreases to 81.67% and 73.33% when storage for 75 d at 4℃and -20℃, respectively. But when storage for 115 d at different temperatures, pollen viability is lower than 20%. It is indicated that short-term (one month) storage at room temperature is suitable to keep pollen viability of P. dabeshanensis, but 4℃is more suitable for keeping pollen viability for longer time..
