VA-mycorrhizal spores were collected from the 14 citurs orchards of different soil textures and locations in Cheju island. Five species and two kinds of spores were identified as based on the morphological characteristics of the spores; Acaulospora bireticulata, Glomus deserticola, G. geosporum, G. vesiculiferum, and Sclerocystis pachycaulis. Additionally, two kind spores of Acaulospora were also observed but difficult to be identified in this moment. Glomus deserticola and unidentified spores of Acaulospora (brown spores sized 90 to $125\;{\mu}m$ in diameter) were most frequently observed in the all soil specimens in Cheju, while the other kinds of spores were rarely observed in the soil of Cheju.

Ten species of the leguminous plants were collected from the soils around Kongiu National University $(127^{\circ}\;08'\;41"\;E,\;36^{\circ}\;28'\;04"\;N)$. All of them were infected with VA-mycorrhizae in the root tissues, and twelve azygospores or chlamydospores of VA-mycorrhizal fungi were found and identified (twelve species of four genera); Acaulospora denticulata, A. scrobiculata, Gigaspora margarita, Glomus australe, Gl. constrictum, Gl. convolutum, Gl. diaphanum, Gl. flavisporum, Gl. glomerulatum, Gl. manihotis, Gl. tortuosum, Scleroystis microcarpus. Seven among them were not reported in Korea yet (seven species of three genera); A. denticulata, Gl. australe, Gl. constrictum, Gl. convolutum, Gl. diaphanum, Gl. flavisporum, S. microcarpus.

Glomus species forming sporocarps were collected at limestone areas in Danyang, on coal mine overburdens in Munkyung, on plantations of Celtis sinensis in the Jindo island and Cryptomeria japonica in the Namhae island, on the Ilchulbong crater base and at a shrubby land near the Chunjiyeon fall. One of the characteristics of Glomus clavisporum is the thick wall ($25-33{\mu}m$) of its cylinderic chlamydospores at the apex. G. heterosporum chlamydospores are loosely connected with each other through brown thick-walled hyphae. G. liquidambaris has paraphysis between chlamydospores. G. rubiforme is blackberry alike. G. sinuosum has a peridium composed of golden yellow thick-walled($2-3{\mu}m$) sinuous hyphae. G. taiwanense has red brown sporocarps with yellow spores of which wall is thickest at the apex.

The symbiotic properties of arbuscular mycorrhizal fungi(AMF) such as the absence and/or presence of symbiosis, spore density, and six factors of phycochemical properties of soil were investigated in the rhizosphere of seven sand dune plants and three control plants around Kum river. The infection of AMF was confirmed in all plants. Three genera, nine species of the AMF spores were identified in the sand dune; Ac. scrobiculata, G. aggregatum, G. convolutum, G. diaphanum, G. dimophicum, G. geosporum, G. vesiculiferum, G. tortuosum, S. pachycaulis. All of them were also found in the control, but S. pachycaulis were only separated in the sand dune. In the control, three genera, four species were identified; G. flavisporum, Gi. margarita, Sc. gregaria. Sc. persica. The species specificity was not found between the sand dune plant and AMF. However, the AMF was thought to be correlated with the soil factors. The spore density was stimulated with increase of the organic matter and the nitrogen content, but inhibited with the water content and the phosphorus content. In respect of the seasonal factor, the spore density was increased in the late growth period of plants.

Status of Arbuscular Mycorrhizal (AM) colonization in seven tree species (Albizia saman, Acacia auriculiformis A. Cunn. ex Benth., Albizia lebbeck, Chickrassia tabularis A. Juss., Eucalyptus camaldulensis Dehnn., Gmelina arborea (Roxb) DC, Swietenia macrophylla King.) collected from the hilly areas of Chittagong University (CU) was investigated. Roots and rhizosphere soil samples were collected in different seasons (pre-monsoon, monsoon and post monsoon). Percentage of AM colonization in root and number of spores/100 gm dry soil were assessed. The result of the investigation reveals that the intensity and percentage of AM colonization varied in different forest tree species in different seasons. In this study, maximum AM colonization and spore population were found in pre-monsoon and minimum were in monsoon season. The intensity of colonization was maximum in C. tabularis (74.43%) in pre-monsoon, A. lebbeck (69.45%) in monsoon and S. macrophylla (67.8%) in post monsoon seasons and minimum in A. auriculiformis (53.75%) during pre-monsoon, A. saman (24.4%) in monsoon and A. saman (19.36%) in post monsoon. The number of spores found per 100 g dry soil ranged between 164-376 during pre-monsoon, 27-310 during monsoon and 194-299 in post monsoon season. Out of six recognized genera of AM fungi, Glomus, Sclerocystis, Entrophospora, Scutellospora, Acaulospora and other unidentified spores were observed.
