Effect of Seed Condition, Stratification, and Germination Temperature on the Laboratory Germination of Loblolly Pine Seed

Stratified and nonstratified loblolly pine (Pinus taeda L.) seed of dormant, nondormant, and weak lots were germinated at 6 temperatures for 28 days. Germination percentages and germination values were evaluated. Constant 22 or 25 ºC is best for laboratory germination. An alternating 20-30 ºC and 30-20 ºC sometimes acted as a mean temperature, a low temperature and a heat sum equivalent depending on the seed condition. Tree Planters' Notes 46(4):139142; 1995.
