        To study the effects of drought stress and Abscisic Acid (ABA) on morpho-physiological and biochemical traits of hemp (Cannabis sativa L.), an experiment was conducted in a factorial based on a completely randomized design at Gorgan University of Agricultural Sciences and Natural Resources in 2017. The treatments included four levels of drought stress (55, 70, 85, and 100 F.C) and the foliar application of abscisic acid (0, 10, 20 and 30 ppm). At flowering stage, growth characteristics and morphology including stem diameter, fresh, and dry weight of shoot, fresh and dry weight of root, stem height, root length, leaf area, leaf number, seed number, flower number, total weight of seeds, number sub branch, sub-branch diameter, total phenolic content, total flavonoid content of root, antioxidant activity, amounts of proline, soluble sugars of root and abscisic acid of leaf were evaluated. ing the amount of leaf abscisic acid, number of branches and total sugars. Based on the results of this study, it can be concluded that water stress has negative effects on plant growth and spraying of the abscisic acid improves some traits in drought stress.
