Title: Food reserves in mountain longleaf pine roots during shoot elongation.

Roots of saplings appear to be models for healthy tissues in longleaf pines. Results show that roots of mountain longleaf pine have a normal anatomy, but also have unusual amounts of starch when compared to loblolly pine roots growing during phenologiexecy equal time periods. Roots appear large in diameter and grow much nearer the soil surface than roots observed from Coastal Plain longleaf pine. Starch grains are large in size and uniformly filled root cells. These results yield methodology potentially useful in assessment of health and productivity of longleaf pine.
