Microbial Ecology

Microbial ecology in cannabis cultivation refers to the complex community of bacteria, fungi, and other microorganisms that colonize plant tissues and growing media. Rather than a terpene, this term describes the biological interactions that influence plant chemistry and secondary metabolite production, including terpene synthesis. Breeders and cultivators increasingly recognize that microbial communities—both beneficial and pathogenic—can affect the expression of volatile compounds and overall plant phenotype. Research into cannabis rhizosphere microbiota has expanded understanding of how microbial partners may modulate plant biochemistry. Understanding these interactions remains an active area of horticultural science with significant implications for consistency and trait expression across generations.

Breeders working with controlled microbial consortia or monitoring rhizosphere health report variation in secondary metabolite profiles across genetically identical plants grown in different microbial environments. Selecting parent plants grown in consistent microbial conditions may improve phenotypic stability in breeding programs.
