Floral Morphology

Floral morphology describes the physical structure and developmental characteristics of cannabis flowers, including calyx shape, pistil arrangement, bract density, and resin gland distribution. Breeders and researchers use morphological traits to distinguish between phenotypes, assess maturity, and identify desirable structural features that influence yield efficiency and cannabinoid expression. Understanding floral architecture is essential for lineage documentation, as consistent morphological markers often correlate with specific parent genetics. Different cultivars commonly exhibit variation in flower compactness, calyx-to-leaf ratio, and pistil coloration—traits frequently selected for in breeding programs. Floral morphology also informs cultivation decisions, as dense versus airy flower structure affects drying time, storage stability, and post-harvest processing.

Breeders select for specific floral morphologies to achieve desired yields, aesthetics, and processing characteristics. Morphological consistency within a line serves as a phenotypic marker for genetic stability and parentage verification across generations.
