Terpene Synthesis Environmental Control

Terpene synthesis in cannabis is influenced by environmental factors including light spectrum, temperature, humidity, and soil composition. Research in cannabis cultivation has documented that UV exposure, cooler nighttime temperatures, and specific nutrient regimens can modulate the expression of terpene profiles across flowering cycles. Breeders and cultivators often study these interactions to understand how environmental conditions shape the volatile organic compound (VOC) expression in different genetic backgrounds. Unlike cannabinoid synthesis, which is largely genetically predetermined, terpene production shows greater phenotypic plasticity—meaning the same plant can express different terpene ratios under varied growing conditions. This environmental responsiveness makes terpene synthesis a useful model for studying gene-environment interactions in cannabis.

Breeders working with terpene-forward selections monitor environmental variables during phenotyping to distinguish true genetic traits from environmentally-induced expression. Understanding environmental terpene control helps breeders identify stable germplasm and predict how cultivars will perform across different production systems and climates.
