Summary
This peer-reviewed study employed a controlled bioassay approach to assess the mycorrhizal status of quinoa (Chenopodium quinoa Willd.), a nutrient-dense pseudocereal of increasing agronomic interest. The authors' classification of quinoa as inconsistently mycorrhizal—meaning it forms variable associations with arbuscular mycorrhizal fungi depending on conditions—has implications for understanding quinoa's soil health relationships and nutrient uptake pathways. The finding suggests that quinoa's mycorrhizal dependency may not be constant across diverse growing environments, which could influence management practices and crop performance in different agricultural systems.
UK applicability
Whilst quinoa is not a traditional UK crop, understanding its mycorrhizal status is relevant to UK growers adopting this species under climate change or for local food system diversification. The findings may inform soil management and inoculant strategies if quinoa cultivation expands in the UK.
Key measures
Mycorrhizal colonisation rates, plant growth response to inoculation, fungal colonisation frequency and intensity
Outcomes reported
The study used a plant–fungus bioassay to evaluate mycorrhizal colonisation patterns in quinoa, classifying the crop as inconsistently mycorrhizal. This characterisation suggests variability in quinoa's fungal associations depending on environmental or cultivation conditions.
