- Abstract
Allelopathy is the main cause of soil sickness of ginseng (Panax ginseng C. A. Mey.) crop, but the source of very effective allelochemicals and their possible physiological damage have not been determined. In this study, we used 5-types of soils viz., (i). Healthy soil (HS), (ii). Soil with stems and leaves extracts (SEL), (iii). Soil + stems and leaves (BS), (iv). Rhizosphere soil (RS) and (v). Continuous cropping problem soil (CCS) in pot culture. We simulated the different release pathways of allelochemicals from ginseng plants and the contents of ginsenoside Rg1, Rb1, Re and Rd were determined in these soils. We determined the activity of soluble protease and antioxidant enzymes in ginseng soil and also monitored the growth and development of ginseng plants. The results showed that the effects of the single allelochemicals release pathway of Panax ginseng followed the order: (RS) > (BS) > (SEL). The ginsenosides Rg1, Rb1, Re and Rd were mainly released as root exudates. The interactions occurred between these ginsenosides in soil, which seemed to be one of the key inducements to cause the oxidative stress injury. This study may provide a theoretical basis to explain the release pathways and accumulation patterns of ginsenoside allelochemical in soil.
