Plant Immunity Compounds

Plant immunity compounds refer to secondary metabolites that cannabis plants produce in response to environmental stress, pathogens, and pest pressure. These include phenolic compounds, alkaloids, and specialized terpenes that serve protective functions in the plant's physiology. Breeders and researchers have observed that certain genetic lines consistently express higher concentrations of these compounds, making them valuable for understanding natural resilience traits. Lineage records frequently report that strains descended from landrace or heirloom cultivars display robust immunity profiles. These traits are typically assessed through phytochemical analysis rather than visual inspection, and their expression varies significantly across phenotypes within the same genetic family.

Breeders working in this category often select parent plants with documented immunity compound profiles to develop lines with improved resilience to environmental stressors and pathogens. Understanding the genetic basis of these compounds helps inform selection strategies for cultivation environments with specific disease or pest pressure histories.
