Stem Pigmentation
Stem pigmentation refers to the coloration of plant stems and petioles, ranging from green to purple, red, or near-black hues. This trait arises from anthocyanin and other pigment accumulation, influenced by genetics, temperature, light exposure, and nutrient availability. Stem color is often visible during vegetative and flowering stages and varies significantly across cannabis cultivars. Documentation of stem pigmentation helps breeders track lineage characteristics and environmental responses. Unlike leaf pigmentation, stem coloration is sometimes more stable under consistent growing conditions, making it a useful phenotypic marker for strain identification and breeding records.

Breeders monitor stem pigmentation as a visual marker for genetic purity, phenotype expression, and environmental stress responses. Consistent stem coloration across generations can indicate stable genetic traits within a breeding line, supporting selection work and cultivar documentation.
