Effects of plant growth-promoting rhizobacteria on growth indicators and physiological characteristics of Peucedanum praeruptorum Dunn leaves

As a kind of medicinal plant, Peucedanum praeruptorum Dunn has been over-harvested in the wild population, which leads to its artificial cultivation. The present study aims to analyze the effects of different plant growth-promoting rhizobacteria (PGPR) on the growth and physiological characteristics of P. Praeruptorum leaves. Compared with the CK, the content of malondialdehyde (MDA) was drastically reduced in the leaves of P. Praeruptorum in different treatment groups (P
