Abstract

Speed of germination affects seedling quantity and quality. This study investigated the effect of germination speed on loblolly pine (Pinus taeda) seedling diameter at lifting. Studies were installed at three forest nurseries in Alabama to test the effects of stratification treatments on speed of germination and of seedling emergence date on final seedling diameter. Results varied with the length of stratification employed. However, in all cases, seedlings which emerged earliest (first 40%) attained significantly larger diameters than seedlings from seeds which germinated later.¹
