▶ AI Summary
The study investigated how tightly controlled drought regimes affect biochemical, physiological, and anatomical traits of three THCA‑dominant Cannabis sativa cultivars. Drought reduced canopy conductance, inflorescence weight, and the concentrations of major phytocannabinoids (THCA, CBGA), while terpene levels varied genotype‑specifically, indicating that yield losses stem primarily from suppressed biosynthetic activity rather than metabolite degradation.
