Plant Structure Dense Flowers

Dense flower structure describes cannabis cultivars that develop compact, tightly-packed inflorescences with minimal spacing between calyxes and bracts. This trait is often associated with indica-dominant genetics and certain landrace populations, though it appears across diverse lineages. Dense flowers typically feature higher resin gland concentration per unit volume, making them of particular interest to breeders developing cultivars for specific end-uses. The compactness can influence drying time, curing requirements, and overall yield density per plant. Breeding programs frequently select for this trait when working toward cultivars suited to controlled environments or specific processing applications.

Breeders targeting dense flower structure often cross proven genetics showing this phenotype, using it as a selection criterion across multiple generations. This trait can affect plant architecture decisions, as breeders balance density with airflow management to reduce disease pressure during cultivation.
