- W896281606 abstract "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. Dates of seed germination were not observed. At the end of the first growing season, survival was good for all sources, but seedlings from the two lower-elevation trees were considerably taller than those from the tree at 5,000 feet. The difference in first-year heights was not surprising because acorns from the two lower-elevation trees were much larger than those from the tree at 5,000 feet. In the second growing season, seedlings from the two lower-elevation trees were well into bud-break by April 7. About 2 weeks later seedlings from the tree at 5,000 feet began bud-break (fig. 1). Some of the seedlings from lower-elevation trees had grown 6 inches or more before the higher-elevation seedlings began bud-break. It appeared as though the seedlings from the two lowerelevation trees would increase their height advantage over those from the higher-elevation trees. This advantage" @default.
