Pine Nursery Stock

Soils of southern pine nurseries are known to contain the beneficial mycorrhizal fungi. What has not been recognized, generally, is that a considerable portion of the seedlings may not become visibly infected with the fungi before they leave the nursery. A recent study in Louisiana showed that the presence of visible mycorrhizae on roots of seedlings of slash pine (Pin us elliottii Engelm.) may be as important as seedling grade in determining survival after outplanting. This suggests the value of insuring greater infection of nursery stock.
