Cytokinin

Cytokinins are plant hormones that regulate cell division and growth in cannabis development. These molecules accumulate in roots and are transported throughout the plant, influencing shoot branching, leaf expansion, and flowering timing. Breeders and cultivators monitor cytokinin levels because they affect plant architecture—higher ratios relative to auxin often promote lateral branching and bushier phenotypes, while lower ratios may encourage apical dominance and vertical growth. Understanding cytokinin expression helps breeders select for specific plant structures suited to different cultivation environments. Genetic lineages are often characterized partly by their natural cytokinin-auxin balance, which contributes to recognizable growth habits across seed lines.

Breeders working with plant structure selection often account for cytokinin sensitivity when developing compact or branching phenotypes. Selecting parent plants with desirable growth architecture indirectly selects for cytokinin-regulated traits that influence yield structure and canopy management.
