Temperature Effects on Dormancy and Germination of Loblolly Pine Seed
Abstract:For after-ripening Pinus taeda seed, 10° C was superior to 5° or 15°, but 5° is recommended to decrease the danger of heating. At 10°, a period of 112 days was required when tests were conducted in darkness. Excellent germination of after-ripened seed was obtained at 17.5° to 27.5°, but there was a tendency toward poor radicle development at the higher temperature.
