Summary

This controlled bioassay study examined the mycorrhizal associations of quinoa (Chenopodium quinoa), a globally important pseudocereal crop. The authors propose that quinoa should be classified as inconsistently mycorrhizal—meaning it shows variable and context-dependent responses to arbuscular mycorrhizal fungi—rather than as obligately or facultatively mycorrhizal. This classification has implications for understanding quinoa's nutrient acquisition strategies and soil management in cultivation.

UK applicability

Quinoa is not widely cultivated in the United Kingdom climate, but findings may inform research into novel crop adaptation and soil inoculant strategies for experimental UK cultivation or breeding programmes seeking stress-tolerant cereals.

Key measures

Mycorrhizal colonisation frequency and intensity; plant growth responses to fungal inoculation

Outcomes reported

The study evaluated mycorrhizal colonisation of quinoa roots using a plant-fungus bioassay to assess the crop's mycorrhizal dependency classification. The research classified quinoa as inconsistently mycorrhizal based on variable fungal colonisation responses.
