Gibberellins

Gibberellins are plant hormones that regulate growth and development across cannabis and other plant species. These endogenous compounds influence stem elongation, flowering timing, and seed germination in cannabis genetics. Breeders and cultivators track gibberellin expression as an indirect indicator of plant vigor and developmental stage progression. Lineage records frequently report that certain seed lines express higher gibberellin activity, correlating with taller plant architecture and delayed flowering onset. Understanding gibberellin dynamics helps breeders select for desired phenotypic traits across generations.

Breeders working in cannabis genetics monitor gibberellin-responsive traits—such as internode spacing and flowering latency—as markers for selecting parent plants with desirable growth characteristics. Exogenous gibberellin application in breeding programs is sometimes used experimentally to manipulate flowering timing or test genetic sensitivity to hormone regulation.
