Abstract: By nutrient solution culture method, effects of benzoic acid, diisobutyl phthalate, diisobutyl succinate, palmitic acid, 2,2-bis(4-hydroxyphenyl) propane on root exudates of Panax ginseng were studied. GC-MS results in-dicated that, 15 to 23 components were detected in treatments including control, which were organic acids, alcohol, amino acid esters, phenols, amines, condensed nucleus, saccharine, etc. Through compared with control we found that, phenol and phenolic acids in root exudates increased in most of stress treatments. So we deduced that, the re-laxation of autotoxins from roots to outside environment was stimulated by autotoxins released into soil, and which ac-celerated the autotoxicity to ginseng seedlings.
