Dense Floral Structure

Dense floral structure refers to tightly packed bract and calyx formations along the flowering sites of cannabis plants. This phenotypic trait is characterized by minimal spacing between individual flower components, resulting in compact, consolidated flower clusters. Dense structure is influenced by genetics, growing conditions, and cultivar lineage—some plant families consistently express this trait across generations. Breeders often observe dense flowers in indica-dominant and hybrid lineages, though expression varies significantly within strain families. The physical density of flowers affects handling, drying, curing, and storage characteristics, making it a practical consideration in breeding programs and cultivation records.

Breeders working with dense floral structure typically select parent plants exhibiting tight bract-to-calyx ratios for consistent expression in offspring. This trait has practical implications for yield per unit volume, post-harvest processing efficiency, and long-term seed storage, making it relevant for both commercial and preservation-focused breeding goals.
