Abstract: The experiments studied the vitality of the pollens of black pines and the Japanese red pines, and established the grading and qualitative regulation of pine pollen. The best method for producing staminate flower pollens from black pines and Japanese red pine was screened. Meanwhile, the optimum drying temperature and treating time of the pine pollens were determined, and the optimum packing way of pine pollen and the criteria of water content during the long-term storage of pine pollens were established.

Key words: black pine pollen, Japanese red pine pollen, vitality, producing pollen, drying, storage
