Licorice (Glycyrrhiza glabra)—Growth and Phytochemical Compound Secretion in Degraded Lands under Drought Stress

Water deficiency restricts plant productivity, while excessive soil moisture may also have an adverse impact. In light of this background, field trials were conducted in secondary saline (EC 6.5 dS m−1) at the experimental station Tashkent State Agrarian University (TSAU), Uzbekistan to determine drought tolerance licorice (Glycyrrhiza glabra) by exposure four levels water deficit, namely control (70–80%), moderate (50–60%), strong (30–40%) and intense (10–20%) relative content (WC) soil. The stress exhibited positive effects on morphological physiological parameters licorice, was considered be most suitable regime for cultivation. Plant growth under 50–60% WC treatment slightly higher as compared 70–80% treatment, exhibiting weak deficit promotes growth, root yield metabolite production. particular, metabolites i.e., ash, glycyrrhizic acid, extractive compounds flavonoids, tended increase however further intensification brought a sharp decline these values. These results contribute development cultivation technologies arid regions important consideration is restoration ecological economical functions dryland agricultural system.
