The Provenance test was performed using seeds from six provenances of eastern white pine(Pinus strobus) originated from USA. The main purpose of this study was to determine the best seed source which shows the best growth in Korea and has the most beautiful tree-form. Seed quality, growth performance in a seed bed and field, and needle characteristics of each provenance were investigated to distribute the seeds after separating seed provenances for wood producing and landscaping. There were a lot of variations in the number of seeds per gram and per litter and the average weight of 1,000 seeds among provenances. In the height growth of four-rear-old trees, Georgia and North Carolina provenances which were heavy in seed weight showed better results than other provenances. The height growth of Pinus strobus started later than that of Pinus koraiensis, but the volume growth of the trees of Pinus strobus started earlier than that of Pinus koraiensis. In the volume growth of 16-rear-old trees, Georgia(71% higher than average value) and North Carolina(61% higher than average value) provenances showed the best growth while Minnesota provenances showed the poorest growth(60% less than average value). Georgia and North Carolina provenances were considered to be appropriate seed provenances for wood producing because of the good tree growth, and New York provenance was considered to be the best seed provenance for landscaping purpose because of the good tree form.
Key words: Pinus strobus, seed quality, seed provenances, Pinus koraiensis
