Plant Biochemistry Fundamentals

Plant biochemistry fundamentals describe the molecular processes through which cannabis plants synthesize cannabinoids, terpenes, and flavonoids. These pathways—including the mevalonate route for monoterpene production and the polyketide pathway for cannabinoid biosynthesis—are shaped by genetics, environmental conditions, and developmental stage. Understanding these mechanisms is essential for breeders seeking to stabilize trait expression, predict chemical outcomes across generations, and develop cultivars with consistent secondary metabolite profiles. Biochemical knowledge also informs cultivation practices, as light spectrum, temperature, and nutrient availability directly influence enzyme activity and compound accumulation.

Breeders working with biochemical principles can select parent plants based on enzymatic capacity and metabolite precursor availability rather than relying solely on phenotypic observation. This knowledge supports rational crossing strategies, helps predict offspring cannabinoid and terpene ratios, and enables development of stable F1 and inbred lines with reproducible chemical signatures across m
