Analysis of the yield and quality of cultivated licorice in China. (A) The age distribution of licorice samples collected in the study, (B) The longitudinal distribution of licorice samples, (C) The root weight of licorice at different ages, (D) The content of glycyrrhizic acid and glycyrrhizin in licorice at different ages. (E) The output of licorice in different provinces (in the sample number, the first letter X refers to “Xinjiang,” G refers to “Gansu,” N refers to “Ningxia,” S refers to “Shaanxi,” M refers to “Inner Mongolia Autonomous Region,” and D refers to the three provinces in Northeast China. The first digit indicates that the age of the collected sample was 2 years; the values from the second to the third digit indicate the sample number under the first letter), (F) Refers to the content of glycyrrhizic acid and glycyrrhizin in licorice in different longitudinal ranges. Different letters in the figure indicates significant differences between groups.
