Training Method Lst

LST (Low Stress Training) is a cultivation technique where growers gently bend and secure branches to manipulate plant architecture without removing tissue. This method works by redirecting auxins—plant hormones controlling growth—to encourage lateral branching and create a more horizontal canopy structure. Breeders and cultivators employing LST commonly report improved light penetration and more uniform canopy development, which can affect breeding selections for plant architecture traits. Unlike high-stress techniques, LST avoids tissue damage and recovery periods, making it relevant for preserving genetic expression during phenotype evaluation. The technique's effectiveness varies with cultivar—some lineages respond more readily to bending than others, providing useful data for breeders assessing plant structure genetics.

Breeders use LST during phenotype hunts and cultivar testing to standardize growing conditions and reveal structural traits without stress-induced morphological changes. Observing how candidate plants respond to LST helps identify desirable branching patterns, internode spacing, and overall architecture for stable breeding lines.
