Use of Mycorrhizal Inoculation for Plant Establishment on Highway Sites

摘要

Three highway soils were tested for presence of spores from mycorrhizal fungi. A newly disturbed soil had virtually no mycorrhizal spores present, while a soil successfully revegetated with herbaceous species and one revegetated with herbaceous and woody species had very high numbers of mycorrhizal spores. Compatibility of plants, commonly used in highway plantings, with mycorrhizal fungi was also examined. Growth of Liriodendron tulipifera was promoted by association with Glomus fasciculatus, and growth of Ligustrum obtusifolia Regelianum was promoted by Glomus mosseae. Inoculum for plants used in highway plantings should include many species of fungi, to compensate for any host specificity.
