Mineral nutrient acquisition in nonmycorrhizal and mycorrhizal plants

1995

Marschner, H. (Hohenheim Univ., Stuttgart (Germany). Plant Nutrition Inst.)

Root-induced changes in the rhizosphere and root colonization with mycorrhizal fungi have marked influence on mineral nutrient acquisition from soils. Enhanced exudation of organic acids under phosphorus deficiency is a widespread phenomena in woody species forming root clusters. Root colonization with endomycorrhizas (AM) and ectomycorrhizas (ECM) increases the spatial availability of nutrients in the soil and enhances plant growth particulary on nutrient-poor soils. Most of these studies have been conducted under controlled environmental conditions and with annual plant species mycorrhizal with AM. Conclusions on the role of ECM colonization for nutrient acquisition of trees in forest stands are not possible at the present state of knowledge.
