Effects of Air Drying on Survival, Height, and Root Growth Potential of Loblolly Pine Seedlings
Loblolly pine (Pinus taeda) seedlings were dried by exposure to ambient conditions and their subsequent quality evaluated for both field performance and root-growth potential. Seedling survival after one growing season was diminished 6.9% and first-year height growth 17% for each 10 minutes of exposure out-doors. Root-growth potential was significantly diminished by air drying with the half-life of a seedling ranging from 15 to 35 minutes depending on ambient conditions. A strong relationship between field performance and root-growth potential was shown. Results support earlier research concluding that seedling desiccation must be avoided if seedling quality is to be maintained at the planting site.¹
