Serrate Margins

Serrate margins refer to the distinctly saw-toothed or jagged edges commonly observed on cannabis leaf blades. This leaf morphology is a visible phenotypic trait influenced by genetics, environmental stress, and developmental factors. The pattern of serration—ranging from fine to coarse—varies widely across strains and cultivars, making it a useful descriptive marker in breeding records and plant identification. Serrate leaf margins are considered a normal characteristic in most cannabis populations, though the degree of expression differs significantly. Breeders and cultivators document serration patterns as part of morphological profiles, particularly when establishing strain stability and phenotype consistency across generations.

Serrate margin expression is tracked in breeding programs as a morphological descriptor for phenotype documentation and plant identification. While not typically a primary selection target, consistent serration patterns help breeders confirm genetic lineage and detect phenotypic drift in stabilized lines.
