Abstract:

The study aims to investigate the differences in inter-root soil metabolites between forest-grown ginseng (PSM) and ginseng grown on farmland (NPSM), and provide a scientific reference for improving the quality of forest-grown ginseng. The study employed GC-MS/MS assay and molecular biology analysis to compare the inter-root soil metabolites of the two types of ginseng. We detected a total of 68 metabolites in the inter-root soil of wild-like forest cultivated ginseng and farmland cultivated ginseng. Among these metabolites, 17 were significantly different, with 14 up-regulated and 3 down-regulated metabolites. The detected metabolites included sugars, lipids, organic acids, esters and other substances. Sugars accounted for 47% of the total significant differential metabolites, which was the largest category of differential metabolites. These different metabolites in rhizosphere soil could directly or indirectly affect the quality of forest ginseng. This study examined the differences in inter-root soil metabolites between forest-cultivated ginseng and farmland-cultivated ginseng. The findings provided a scientific reference for improving the quality of forest-cultivated ginseng and exploring the cultivation environment of forest ginseng to overcome the obstacles of ginseng continuous cropping, improving the medicinal and edible value of forest ginseng and to provide new ideas and methods for the rural revitalization strategy of the understory ginseng industry in the northeast region of China.
