Eastern White Pine Seed Source Variation in the Northeastern United States: 16-Year Results
Twelve eastern white pine ( Pious strobus L.) provenance plantations in the northeastern United States were measured for 16-year height and diameter. Differences in height between northern and southern sources have diminished since the 10-year measurements. In general, the 16-year diameter measurements follow the same trends as do the 16-year-height measurements. Recommendations for selection and movement of seed from one region to another are discussed.
