Plant Structure

Plant structure refers to the physical architecture and morphology of cannabis plants, including characteristics like internode spacing, branching patterns, leaf blade width, and overall height-to-width ratio. These traits are genetically determined and significantly influenced by environmental conditions such as light intensity, temperature, and photoperiod. Breeders categorize plants into broad types—such as compact/bushy, tall/columnar, or intermediate forms—to predict growth behavior and optimize cultivation strategies. Understanding plant structure is essential for indoor and outdoor production planning, canopy management, and breeding objectives. Structure differs from yield or cannabinoid profile; it describes the plant's physical form rather than its chemical composition or potency.

Breeders select for specific plant structures to match growing environments (height-restricted indoor spaces, outdoor wind tolerance) and to improve cultivation efficiency. Structure traits are often combined with other agronomic characteristics to develop stable cultivars suited to particular production systems.
