Faster acquisition of symbiotic partner by common mycorrhizal networks in early plant life stage
Abstract Arbuscular mycorrhizal ( AM ) fungi usually improve plant performance yet our knowledge about their effects on seed germination and early plant establishment is very limited. We performed a factorial greenhouse experiment where the seeds from four low Arctic co‐occurring mycorrhizal herbs (...

We performed a factorial greenhouse experiment where the seeds from four low Arctic co‐occurring mycorrhizal herbs ( Antennaria dioica , Campanula rotundifolia , Sibbaldia procumbens , and Solidago virgaurea ) were germinated alone or in the vicinity of an adult Sibbaldia plant with or without AM fungi; given either as spores or being present in a common mycorrhizal network ( CMN ).
