Mild Drought Promotes Biomass Accumulation and Increases Diosgenin Content in Rhizomes of <i>Dioscorea nipponica</i>.

ABSTRACT: Dioscorea nipponica is an important medicinal and edible plant in northern China, and its extract dioscin is an important raw material for the modern pharmaceutical industry. To investigate the key environmental factors influencing diosgenin accumulation in the rhizomes of D. nipponica and their action mechanism, we collected wild D. nipponica plants from 60 plots on Zhongtiao Mountain and analyzed the effects of environmental conditions on both plant growth and diosgenin synthesis. Additionally, physiological parameters of D. nipponica were investigated under different intervals of watering treatments: control (CK, 3 days), mild drought (MID, 5 days), moderate drought (MD, 8 days) and severe drought (SD, 10 days). The results showed that the water content of rh
