Distribution of Arbuscular Mycorrhizal Fungi in Greenhouse Strawberry Plants

This study was conducted to investigate into the distribution of arbuscular mycorrhizal fungi (AMF) in the greenhouse soils grown strawberry plants in Damyang and Jangheung districts. Twenty three soil samples were collected from strawberry plants under greenhouse conditions, and mycorrhizal spores in soils were separated using wet-sieving methods. Number of mycorrhizal spores per 30g fresh soil sized over 500${\mu}$m, 355~500${\mu}$m, 251~354${\mu}$m, 107~250${\mu}$m and $45{\sim}106{\mu}m$ were 0.3, 1.0, 4.2, 50.4 and 119, etc. Total number of spores per 30g fresh soil were l73.9. Root infection by vesicles and hyphae were 25% and 4%, respectively. Mycorrhizal root infection by arbuscules was not shown in strawberry roots. Isolated mycorrhizal spores were inoculated into the host plant of sudangrass to identify the genus of arbuscular mycorrhizal fungi, and propagated for 4 months. As a result of identification, mass propagated mycorrhizal spores were Glomus sp., Gigaspora sp., and Acaulospora sp., and so on.
