V. A. Mycorrhizae가 미국삼의 생육에 미치는 영향

Effects of Vesicular-Arbuscular Mycorrhizae on The Growth of American Ginseng

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%.
