This study was conducted to investigate into the marketing states of ‘Hangalku (Cirsium japonicum DC.)’ for the soup stock of wild vegetables with Jangheung as the central districts, and to clarify the distribution of arbuscular mycorrhizal fungi in the native soil and roots of Cirsium japonicum DC. Hangalku for wild vegetables was used for the soup stock with soft leaves and roots. Total fresh and dry weights of leaves per 1,000won were 226.0g and 24.6g. And total root fresh and dry weights by 1,000won were 175.6g and 37.5g. Leaf fresh and dry weights of Hangalku per plant sold for wild vegetables were 9.1g and 0.9g, and number of leaves was 10.8. Root fresh and dry weights of Hangalku per plant were 19.2g and 4.1g. Thirty five soil samples were collected from the native soils grown Cirsium japonicum DC., and mycorrhizal spores in soils were separated using wet-sieving methods. Number of mycorrhizal spores per 30g fresh soil sized over 500㎛, 355~500㎛, 251~354㎛, 107~250㎛ and 45~106㎛ were 0.6, 2.1, 6.0, 55.3 and 126, etc. Total number of mycorrhizal spores per 30g fresh soil were 190. Root infection by vesicles, hyphae and arbuscules were 13%, 4% and 3%, respectively. As a result of identification, mass propagated mycorrhizal spores by the host plant of sudangrass were Glomus sp., Gigaspora sp., and Acaulospora sp., and so on.
