Abstract:

The growth of red maple was increased when the plants, grown in either sand or anthracite waste containing bonemeal, were infected with Glomus macrocarpus var. geosporus or Gigaspora gigantea, respectively. The importance of phosphate and nitrate for normal development was shown in plants grown in sand culture. Mycorrhizal plants grown in sand or anthracite contained more phosphorus than nonmycorrhizal plants. Effects of the various nutrient treatments and mycorrhizal infection on the size of the plants, leaf numbers, leaf areas, stem anatomy, and chemical composition of the plant tissues are reported. Both the secondary and beaded tertiary roots became infected with the fungal endophytes. The possible exploitation of this symbiosis on anthracite spoil areas is discussed. Forest Sci. 23:207-216.
