The underground part of plants is not only an important part for plants to obtain nutrients from the outside world, but also an impor-tant place for the synthesis and transformation of various hormones, organic acids and amino acids in plants. The medicinal plants with the un-derground part as the main medicinal part, the growth status of the underground part directly affects the yield and quality of the medicinal ma-terials, and indirectly affects the income of the farmers, the therapeutic effect of the disease, the health level of the people and so on. In re-cent years, with the deepening of the research on the underground part of medicinal plants, the influencing factors related to their growth and development have received increasing attention. Therefore, this paper reviews the effects of environmental factors and hormones on the under-ground part of plants and the molecular mechanism of underground growth and development, so as to provide reference for further research on the underground part of medicinal plants.
