Abstract
Ericoid mycorrhizae were measured on roots of wild and cultivated highbush blueberries (Vaccinium corymbosum L.) from 7 locations in southeastern North Carolina over 4 sampling dates. An adequate clearing and staining procedure was developed specifically for observing endomycorrhizae in blueberry roots. Abundant mycorrhizae were found in wild blueberry plants, but few mycorrhizae were noted in cultivated plants. Phosphorus levels were lower in the wild than in the cultivated blueberry soils at most locations.
