Oxidation Markers

Oxidation markers refer to chemical compounds and browning patterns that develop in cannabis plant material over time, influenced by exposure to oxygen, light, and temperature. These include chlorophyll degradation, carotenoid conversion, and the formation of secondary metabolites that alter flower color from green to brown, red, or purple hues. Breeders and cultivators monitor oxidation progression as an indicator of harvest timing, cure quality, and storage stability. The rate and extent of oxidation varies significantly across genetic lines, with some cultivars showing rapid color shifts while others maintain structural integrity longer. Understanding oxidation markers helps distinguish between genetics-driven pigmentation and degradation caused by environmental stress or improper handling.

Breeders select for oxidation resistance when targeting shelf stability and long-term potency retention in seed lines intended for commercial cultivation. Conversely, some breeding programs intentionally work with rapid oxidation traits to develop visually distinctive cultivars or to understand senescence genetics.
