Research focus: Mechanisms of weed suppression in Chenopodium quinoa
Conventional agriculture and climate change are driving major changes in natural ecosystems, increasing the demand for resilient and diversified cropping systems. Chenopodium quinoa is a nutrient-dense and stress-tolerant crop with strong potential for sustainable agriculture. Field observations indicate that certain quinoa genotypes exhibit weed-suppressive properties; however, the molecular and ecological mechanisms underlying this effect remain poorly understood. Weed suppression in quinoa is likely mediated by a combination of competitive interactions and allelopathic effects.My research aims to unravel the mechanisms responsible for weed suppression in quinoa by linking genotype-specific traits to the production and activity of phytotoxic metabolites. In particular, I investigate the identity of these compounds and the biochemical processes through which they inhibit growth in other plant species.Elucidating these mechanisms will facilitate the development of more resilient cropping systems by enabling the targeted use of weed-suppressive quinoa genotypes and their associated bioactive compounds.
