Effects of soil and genotype mediated root exudates on the quality of Salvia miltiorrhiza

This study used in-situ soil from five different cultivation areas (Beijing, Henan, Sichuan, Shandong, Shaanxi) to plant 4 different varieties of Salvia miltiorrhiza. At the same time, Beijing soil was separately selected for bacterial agent pot experiments. These root exudates were collected at different growth stages of Salvia miltiorrhiza for metabolomics detection and analysis. The effects of different soil types and genotypes mediated root exudates on Salvia miltiorrhiza quality were observed, as well as the effects of different microbial agents mediated root exudates on the active ingredients of Salvia miltiorrhiza.
