Kiln Temperatures for Northern White Pine Cones
Abstract:Kilns have been used for extracting conifer seeds from cones for a considerable number of years. However, until comparatively recently these kilns were operated largely on an empirical basis. In the present paper results are reported of carefully controlled studies to determine safe working temperatures and humidities. The work of Messrs. Rietz and Torgeson shows that a kiln treatment up to 140° F. for a duration of 12 hours did not reduce the vigor of germination of white pine seed. Kiln temperatures of 160° F. definitely reduce the viability of the seed.
