Bud-Break on Red Oak Seedlings Varies With Elevation of Seed Source

Observation of northern red oak (Quercus rubra L.) seedlings for three growing seasons has indicated a probable relationship between elevation where the seed source grows and the time of budbreak. Seedling survival and growth following late spring frosts in the second and third growing seasons showed that time of bud-break may be a critical factor in selecting planting stock for a given site. These observations add to our knowledge about the importance of the source of seed in forest planting. Open-pollinated seed from three trees were collected in the fall of 1965 and placed in cold storage. In the spring of 1966, 270 seedlings from each mother tree were established in nursery beds at Bent Creek Experimental Forest in western North Carolina, at an elevation of 2,100 feet. One of the mother trees was located at an elevation of 5,000 feet, the second at 3,300 feet, and the third at 2,700 feet. The mother trees and the planting site were within 40 miles of each other.
