Chlorophyll Dominance

Chlorophyll dominance refers to plants that maintain unusually high chlorophyll concentrations throughout flowering, resulting in deep green foliage even at harvest. This trait is influenced by genetics, environmental conditions (light, temperature, nutrient availability), and phenotypic expression within a strain family. Cannabis lineages bred from parents showing strong chlorophyll retention often produce offspring with similarly robust green coloration. Breeders working with chlorophyll-dominant genetics have frequently observed extended vegetative vigor and delayed senescence patterns. This trait appears across multiple cannabis families and is sometimes associated with specific indica or sativa-dominant backgrounds, though expression varies significantly by phenotype and cultivation conditions.

Breeders select for chlorophyll dominance when seeking cultivars with extended metabolic activity or distinctive visual phenotypes. This trait can correlate with delayed maturation schedules and may influence nutrient cycling and overall plant structure during the flowering window.
