Germination temperatures for container culture of southern pines

Abstract

Peak germination of unstratified longleaf, shortleaf, loblolly, and slash pine seeds occurred at 75° F. Longleaf seeds germinated better at lower temperatures and less successfully at higher temperatures than those of slash, loblolly, and shortleaf pine. Stratification broadened the range at which slash, loblolly, and shortleaf germinated satisfactorily. Improvement in germination was greater at temperatures below 75° than above 75°. Temperatures of 95° resulted in low germination under all conditions.
