Green Plant Volatiles

Green Plant Volatiles (GPVs) are a class of organic compounds produced by cannabis and other plants in response to environmental stress, herbivory, or developmental stages. Common GPVs in cannabis include hexanal, hexenal, and hexenol—compounds that create fresh, grassy, or leafy aromatics often detected in early-stage plant material or live-resin products. These volatiles are frequently detected in younger plants or those exposed to mechanical stress, making them markers of harvest timing and post-harvest handling conditions. GPV profiles are less stable than monoterpenes or sesquiterpenes, degrading or transforming during drying and curing. Understanding GPV expression helps breeders and cultivators assess plant stress responses and optimize preservation techniques for aromatic integrity.

Breeders track GPV expression as an indicator of plant vigor, stress tolerance, and terpene stability during development. Cultivators use GPV profiles to monitor harvest readiness and evaluate post-harvest processing methods that preserve or reduce grassy notes.
