Plant Structure Development

Plant structure development encompasses the genetic and phenotypic traits that determine how cannabis plants grow—including internode spacing, branching patterns, leaf morphology, and overall architecture. Breeders have long selected for structure traits to optimize cultivation environments, yield potential, and cannabinoid/terpene expression. Structure is influenced by both nuclear genetics and environmental factors, making it a complex trait for reproducible breeding programs. Understanding structural genetics helps cultivators and breeders predict plant behavior across different growing conditions and breeding objectives. Key structural variants range from compact, bushy phenotypes to tall, open-canopy types, each suited to different production systems.

Breeders actively select for specific structural traits to match cultivation methods (indoor versus outdoor), light penetration, pest management, and harvest efficiency. Structural stability and consistency across generations is a primary selection criterion in modern cultivar development.
