Ginsenoside contents (%) of four-year-old P. ginseng roots. a Mixed standards. b HPLC chromatogram profiles of P. ginseng roots. c Contents of Rg1, Re, Rb1, Rc, Rb2, and Rd in P. ginseng roots. CK represents the treatment without biofertilizers. T1-L, T1-M, and T1-H represent treatments with growth-promoting biofertilizers at low, middle, and high concentrations, respectively. T2-L, T2-M, and T2-H represent treatments with disease-biocontrol biofertilizers at low, middle, and high concentrations, respectively. Data are presented as mean ± SD (n = 3). Identical letters denote insignificant differences among treatments at the same developmental stage at the 0.05 level
