Green Plant Volatile

Green Plant Volatile (GPV) compounds are C6 aldehydes, alcohols, and esters produced when cannabis plant tissue is damaged or stressed, commonly associated with fresh-cut grass, green leaf, and herbal aromatics. These volatile organic compounds are synthesized through the lipoxygenase (LOX) pathway and represent early plant defense chemistry rather than cannabinoid or terpene biosynthesis. GPV profiles are frequently observed across diverse cannabis genetics and often intensify during harvest, drying, or processing when cell walls rupture. Breeders studying GPV expression are typically interested in understanding how these volatiles interact with other aromatic families to shape cured phenotype character. The GPV family includes compounds like hexanal, hexenal, and hexenol, which may evolve significantly during cure and storage as plant enzymes remain active.

Breeders working in preservation and post-harvest optimization monitor GPV profiles to predict how fresh-plant aromatics will transform during drying and cure phases. Understanding GPV expression helps inform decisions about cultivar selection for specific consumer or commercial processing pathways, as these volatiles directly influence early-stage aroma development.
