- Intervention effect Intensive culture significantly altered slash pine root surface area and distribution.
- Association Airlayers and seed-grown trees did not differ significantly in shoot growth.
- Observation All seedlings had well-defined taproots.
- Observation Most airlayers had one to three heavy sinker roots reaching maximum rooting depth.
- Observation Half of total root surface area was in the surface 0.3 m of soil.
- Observation Six percent of total root surface area occurred below 1.35 m.

- Observation Within 1 m of the bole, 24% of roots were below 1.35 m.
- Observation Roots under 2 mm diameter made up half of total root surface area.
- Association Vegetative propagules developed as well as seedling stock.
- Observation Both vegetative propagules and seedling stock rooted profusely to 2.5 m.
