Moisture content and temperature were the most important factors in inducing secondary dormancy. Length of storage did not strongly influence the percentage of dormant seed. Secondary  dormancy was induced by reducing moisture content to 13% or less and/or by exposing seed to temperatures of 23oC or higher for 48 hours. Both seed sources and seed sizes reacted in a similar to treatments used to induce secondary dormancy.  adormancy  aDormência  aPinus Taeda  aSemente  aSeed
