  • Of the 103 species (41 families) sampled from two limestone bites in Korea, 98 species (95.1%) contained VA mycorrhizae. No mycorrhizal structures were observed in the other 5 species. The nonmycorrhizal species were members of the following 4 families: Equisetaceae, Davalliaceae, Amaranthaceae and Ericacene. Of the 124 species (51 families) sampled from two different nonlimestone sites, 99 species (79.8%) were found to contain VA mycorrhizae and no mycorrhizal structures were observed in the other 25 species. The nonmycorrhizal species were members of the following 16 families: Equisetaceae, Pteridacaea, Davalliaceae, Cyperaceae, Commelinaceae, Polygonaceae, Chenopodiaceae, Phytolaceaceae, Amaranthaceae, Aizoaceae, Portulacaceae, Caryophyllaceae, Fumariaceae, Cruciferae, Ericaceae and Rubiaceae.

  • Mulberry Seedlings germinated and grown under green house conditions were inoculated with Glomus mosseae, Mosse and Trappe (a Kind of Vesicular arbuscular mycorrhizae) prior to outplanting into unsterilized soil. They were grown on phosphate deficient soil for 6 months after planting. Shoot length, stem diameter and leaf yield of the inoculated plants were found to be significantly greater than uninoculated ones. It was observed in foliar mineral content that the levels of N, P$_2$O$\sub$5/, CaO of the inoculated plants were higher but the level of MgO of the inoculated plants was lower than the uninoculated ones. In the mineral content of roots, it was observed that the level of P$_2$O$\sub$5/ was higher but the level of N was lower significantly in the inoculated plants than the uninoculated ones.

  • 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%.

  • Out of the 36 species (22 families) of horticultural plants collected from the horticultural shop around Cheong Ju, the 17 plant species (47.2%) were infected with VA-mycorrhizae in the root tissues. Also, the chlamydospores or azygospores of VA-mycorrhizae were identified (two genera, three species); Acaulospora spinosa, Glomus etinucatum, and G. tortusom. VA-mycorhizae found from the cultivated plants around Korea National University of Education and other area were also identified (four genera, six species); A. myriocarpa, Gigaspora decipiens, G. caledonium, G. glomerulatum, G. microcarpum, and Scutellospora calospora.

  • Vesicular-arbuscular mycorrhizal fungi were isolated from the soils of three different plant communities (Cassia mimsoides var. nomame, Themeda triandra var. japonica, Miscanthus sinensis var. purpurascens). Eight azygospores or chlamydospores of VA-mycorrhizal fungi were identified (eight species of four genera), and six among them newly described in Korea (six species of two genera); Glomus aggregatum, Gl. ambisporum, Gl. geosporum, Gl. mosseae, Scutellospora coralloidea, Sc. heterogama.

  • This study was carried out to acguire some basic information on nutritional and lhysiological effects of vesicular arbuscular mycorrhizae(VAM) on mulberry trees inoculated with Glomus mosseae, Gerd. & Trap. grown in clay for 65 days and treated with 5 different levels of phosphorus, ie 30, 60, 120, 240, 480 ppm as (NH4)2 HPO4. At the End of the expermental period the levels of fixed phosphate in the soil was measared. And the native VAM fungi were collected to select the most effective VAM species on mulberry tree. The nutritional and biochemical effects of VA mycorrhizae on the mulberry leaves were also studied. Those results are as follow. 1. The mulberry trees grown in clay and inoculated with VAM were heavier in shoot dry weight as much as 197% than uninoculated plants. But in vermioulite, uninoculated mulberry trees were heavier as much as 135% than inoculated. 2. The rates of endo mycorrhizal formation in clay was highest at 60 ppm level of phosphorus, and vesicles in roots were formed in 240ppm and 480ppm level of phosphorus, but not in 30ppm, 60ppm and 120ppm. 3. The greatest growth responses of VAM inoculation was found at 60ppm level of hosphorus, and the optimum phosphorus level for VAM responese appeared to be 60ppm. 4. VAM was also to absorb soil-fixed phosphate. VAM abosrbed Fe-bound phosphate most efficiently and Ca-bound phosphate with ease but not Al-bound phosphate and Al-Fe occluded phosphate. 5. Three species of Gigaspora and one species of Glamus growing naturally in mulberry plantations were collected and tested for the growth responses. Gigaspora tricalipta and Gigaspora calospora revealed the greatest growth responses on mulberry tree among tested VAM fungi. 6. Mulberry leaves inoculated with VA mycorrhizal fungi contained 9.8% more phosphate and 15.2% more nitrogen, 22.2% more water-soluble carbohydrates and 15.2% more proteins than uninoculated plants. 7. The electrophoretic pattern of mulberry leaf protein inoculated with VAM fungi has 19 bands. 8. The patterns of peroxidase zymogram and Amulase zymogram were different between the mulberry leaves inoculated and uninoculated with VA mycorrhizal fungi. The peroxidase zymogram of inoculated leaves has 1 less majour band than unioculated leaves The amylase zymogram of inoculated leaves has 2 bands near the +pole, but that of uninoculated leaves has 1 band near the $pole.

Growth Stimulation of Alnus firma and Robinia pseudoacacia by Dual Inoculation with VA Mycorrhizal Fungi and Nitrogen-Fixing Bacteria and Their Synergistic Effect (VA 내생균근균(內生菌根菌)과 질소고정균(窒素固定菌)으로 이중접종(二重接種)한 사방오리나무와 아까시나무의 생장촉진(生長促進)과 접종(接種)의 상승효과(相乘效果))

  • To evaluate potential of VA mycorrhizal fungi for promoting growth of nitrogen-fixing trees and efficiency of fungal inoculation in relation to soil fertility and dual inoculation with bacteria, Alnus firma was grown for six months in pots with steam-sterilized soil after inoculation with Glomus mosseae, and Robinia pseudoacacia was grown in the fumigated field after inoculation with native Glomus sp. and Gigaspora sp. In unfertilized Alnus plants, 27% increase in dry weight(or 18% in height) was observed by Glomus inoculation, while plants inoculated with both VA mycorrhiza and actinomycete(crushed nodule inoculum) showed synergistic effect of 83% dry weight increase over uninoculated plants. In fertilized Alnus plants, mycorrhizal inoculation alone or dual inoculation with actinomycete resulted in depression of height and dry weight of plants. In case of Robinia, dual inoculation stimulated height growth by 23% (or dry weight by 25%) over the control in unfertilized field, while 13% more height growth(or 21% more dry weight) was observed in fertilized field. It is concluded that VA mycorrhizae, especially Glomus mosseae, have a potential for growth enhancement in Alnus, that synergistic effect of dual inoculation(mycorrhiza + actinomycete) exists in both Alnus and Robinia, and that responses of these plants to VA mycorrhiza are more pronounced in unfertilized soil.

  • A search for presence of Versicular-Arbuscular endomycorrhiza was attempted using 6-year-old Panax ginseng roots. Hyphae without septum, and vesicles were observed in the cortex of fine roots of Panax ginseng. Brown chlamydospores with thick wall were found in the soil of root zone and it is classified as Glomus sp.
