Dry Site Survival of Barefoot and Container Seedlings of Southern Pines from Different Genetic Sources Given Root Dip and Ectomycorrhizal Treatments
Survival rates of loblolly pine (Pinus taeda L.) seedlings from two seed sources and shortleaf pine (P. echinata Mill.) seedlings from one source were compared for the first 2 years after outplanting on drought-prone sites. Several combinations of stock type and preplanting treatments were examined: bareroot seedlings with no pretreatment, bareroot seedlings treated with Terra-Sorb® root dip, container seedlings, and container seedlings inoculated with ectomycorrhizae. Survival rates were not significantly different for seed sources. However, after two growing seasons, bareroot seedlings survived better than . container seedlings and container seedlings with ectomycorrhizae on the most severe sites. On a more moderate site, container seedlings showed the highest survival, and treated bareroot seedlings showed higher survival rates than untreated bareroot seedlings.
