Newly sprouted American ginseng (Panax quinquefolium L.) seedlings were transplanted to forest pots with mycorrhizae-infested soil and grown in screenhouse for 2 years. Growth patterns, mortality rate and fresh root weight were investigated. Plants in VAM soil had lower mortality rales than control. In soils infested with two species of mycorrhizal fungi (Glomu deseyicola, frappe, Bloss and Merge and G. intraradices, Schenck and Smith), 28-35% of plants produced 3-prongs in the second season and significantly increased fresh root weight by 41 to 43%.
