Plant Phytochemistry

Plant phytochemistry encompasses the diverse array of organic compounds naturally synthesized by cannabis plants, including cannabinoids, terpenes, flavonoids, and phenolic compounds. These secondary metabolites develop through the plant's biosynthetic pathways and accumulate primarily in trichomes—the resinous glands covering flowers and leaves. Phytochemical composition varies significantly across cultivars due to genetics, environmental conditions, and cultivation practices, making it a central focus of cannabis breeding research. Understanding phytochemistry is essential for lineage documentation, as chemical profiles often correlate with known parent genetics and regional breeding populations. Breeders and researchers use phytochemical analysis to verify cultivar authenticity, track trait inheritance, and select for specific compound ratios in breeding programs.

Breeders leverage phytochemical profiling to select parent plants with desired compound combinations and to verify breeding outcomes through laboratory testing. Tracking phytochemical expression across generations helps establish stable cultivar standards and informs decisions about backcrossing, hybridization, and line stabilization.
