Effects of long-term water reduction and nitrogen addition on fine roots and fungal hyphae in a mixed mature Pinus koraiensis forest

The lack of synchronous studies on fine roots and fungal hyphae makes it difficult to gain insight into changes in how mycorrhizal trees search for nutrients under reduced precipitation increased nitrogen deposition. We applied a modified version the ingrowth bag approach estimate community-level responses long-term water availability mixed mature forest. Water reduction, addition two treatments combination decreased root length density, biomass hyphal with lowest values occurring combined treatment. Compared control treatment, reduction treatment had thinner diameter, lower branching intensity greater specific length. Fungal significantly diameters than at 0–10 cm soil depths. Root biomass, density increasing depth. In contrast, diameter was positively related but negatively diameter. Forest respond plastically availability. An integrative simultaneous understanding both trait plasticity can provide better insights resource acquisition strategies experiencing environmental changes.
