Description

  • This article investigates the effect of using mycorrhizae from four native species (Inga acreana, Tabebuia chrysantha, Cedrela montana and Heliocarpus americanus) to inoculate nursery grown seedlings of two of the native species (C. montana and H. americanus).
  • First, a preliminary trial germinated seeds from the four species and planted the seedlings with a substrate of sterilized mine sand and humus from the mountain rainforest.
  • After 6 months the plant roots were harvested and observed for mycorrhizae.
  • For 150 plants of H. americanus and C. montana, some seedlings were inoculated with mycorrhizal roots of the same species, some with a mixture of all four species, and some were not inoculated.
  • Additionally, fertilizer was added to some plants in each category.
  • The authors found that tree seedling growth was significantly improved by the inoculation with mycorrhizae of either individual tree species or the mixture of the four tree species.
  • The moderate fertilization improved growth in H. americanus but not in C. montana.
  • The authors assert that inoculation of mycorrhizae into nursery seedling soils can help improve the viability of those native species for reforestation.
