Overview

Greenhouse and field experiments reveal how mycorrhizal type and light availability affect biomass in trees, indicating complex soil dynamics.

Key Points

  • To examine how mycorrhizal identities of tree seedlings and adults, along with light conditions, impact biomass-based plant-soil feedbacks.
  • Conducted greenhouse and field experiments with various tree species
  • Tested biomass responses under different mycorrhizal interactions and light regimes
  • Analyzed soil conditioned by conspecifics and heterospecifics
  • AM species showed negative plant-soil feedbacks under low light, shifting to neutral or positive in higher light
  • EM species generally had positive feedbacks across light levels, but with species-specific variations
  • Field results sometimes differed from greenhouse findings, particularly for certain EM species
