Morphology Plant Structure

Plant morphology refers to the physical structure and architectural characteristics of cannabis plants, including height, branching patterns, leaf shape, and internode spacing. Breeders and cultivators assess morphological traits to predict yield potential, space efficiency, and growing requirements. Different morphotypes—such as tall, columnar plants versus compact, bushy specimens—suit different cultivation environments and techniques. Understanding morphology is fundamental to breeding programs, as these traits are heritable and influence how a plant develops across vegetative and flowering stages. Morphological classification helps growers select cultivars matched to their space, training methods, and production goals.

Breeders deliberately select for specific morphological traits to create cultivars suited to indoor, outdoor, or greenhouse production. Compact, short-stature plants may be crossed to produce high-density crops, while vigorous, tall phenotypes are chosen for outdoor cultivation or to maximize canopy surface area.
