The Effects of Seed and Seedling Size on Survival and Growth of Loblolly Pine

In studies of morphological grades of slash and longleaf pine seedlings, Wakeley (9) found that large seedlings tended to grow faster than small seedlings but survival was lower. Many small seedlings survived and grew well. The physiological condition of the seedlings was more important than the morphological grade. In a study with loblolly pine seedlings (10), large seedlings grew faster than the smallest grade and survived better. By age 34 years, seedlings of the largest grade had produced twice as much volume per unit area. Other studies with loblolly pine in Texas have shown that a large planting stock maintains a growth advantage over small stock for several years (5,6,7).
