OSTI ID:6441596
This study was undertaken to ascertain the significance of loss of ectomycorrhizae encountered during lifting of nursery seedlings to the capacity of the seedlings. Loblolly pine seedlings with abundant Pisolithus tinctorius (Pt) or naturally occurring (NI) ectomycorrhizae were nursery grown. Seedlings from the 2 groups were graded to similar sizes and either 100, 66, 33 or 0% of the ectomycorrhizae were removed to simulate degrees of roughness in machine handling of seedlings. The 8 treatments were outplanted on an upland site in a complete randomized plot design. Although the results are only preliminary at this time, they do indicate that seedlings with intact Pt ectomycorrhizae survive better, regenerate more roots, and initiate more height growth than seedlings with their roots stripped to different degrees. Generally, seedlings with Pt ectomycorrhizae are doing better than those with NI ectomycorrhizae. 1 table.
