  • 화삼회토양에서 감귤대목으로 사용되는 탱자 유모의 생육에 미치는 arbuscular mycorrhizae(AM)의 영향을 조사하기 위하여, N, P, K 시비수준을 달리한 화산회토에서 감귤뿌리를 접종 재료로 하여 AM균을 접종시킨 탱자 유묘를 재배하였다. 유모의 생육과 식물체내 무기 함량을 분석하고 감염된 화분토양에서 채취한 포자의 종류를 동정하였다. 토양 5L당 21-17-17 복비 40g과 용성인비 50g을 준 다비인산구에서만 감염된 화분의 비율이 70%였고 나머지 인산을 첨가하지 않거나 시비량이 적은 처리들에서는 감염 비율이 20% 이하였다. AM 형성율의 증가에 따라 지상부의 생채중과 건물중은 유의하게 증가 되었으며, 초장과 지하부 생채중 및 건물도 5% 수준에서 유의성은 인정되지 않았지만 증가하는 경향이었다. 따라서 식물체 내의 P와 Cu, Mg의 함량은 AM 형성율의 증가에 따라 비례적으로 유의하게 증가하였으며, N과 Zn의 함량도 증가하지만 Ca 함량은 감소하는 경향이었다. 접종 재료를 채취한 토양에서 발견되는 Glomus desertcola, G. rubiforme, G. vesiculiferm 과 Acaulospora sp. 등 4종의 AM균 포자 모두가 접종된 화분토양에서도 확인되어 이들 균이 모두 탱자 뿌리에서 AM을 형성하는 것으로 판단되었다. 토양중의 인산 수준이 감귤 뿌리의 AM균 감염을 결정하는 요인으로 작용하는 것 같으며 감귤원에서 AM을 효과적으로 이용하기 위해서는 우선 AM의 형성율을 높일 수 있는 적정 토양 인산 수준에 대한 연구가 이루어져야 할 것이다.

  • Results from an innovative approach to improve remediation in the rhizosphere by encouraging healthy plant growth and thus enhancing microbial activity are reported. The effect of arbuscular mycorrhizal fungi (Am) on remediation efficacy of wheat, mungbean and eggplant grown in soil spiked with polyaromatic hydrocarbons (PAH) was assessed in a pot experiment. The results of this study showed that Am inoculation enhanced dissipation amount of PAHs in planted soil, plant uptake PAHs, dissipation amount of PAHs in planted versus unplanted spiked soil and loss of PAHs by the plant-promoted biodegradation. A number of parameters were monitored including plant shoot and root dry weight, plant tissue water content, plant chlorophyll, root lipid content, oxido-reductase enzyme activities in plant and soil rhizosphere and total microbial count in the rhizospheric soil. The observed physiological data indicate that plant growth and tolerance increased with Am, but reduced by PAH. This was reflected by levels of mycorrhizal root colonization which were higher for mungbean, moderate for wheat and low for eggplant. Levels of Am colonization increased on mungbean > wheat > eggplant. This is consistent with the efficacy of plant in dissipation of PAHs in spiked soil. Highly significant positive correlations were shown between of arbuscular formation in root segments (A)) and plant water content, root lipids, peroxidase, catalase polyphenol oxidase and total microbial count in soil rhizosphere as well as PAH dissipation in spiked soil. As consequence of the treatment with Am, the plants provide a greater sink for the contaminants since they are better able to survive and grow.

  • 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.

  • A sucrose-agar globule (SAG) was newly introduced to increase production of the vesicular arbuscular mycorrhizal (VAM) fungal spores, Gigaspora gigantea and Glomus fasciculatum. An SAG inoculum and a sucrose-agar globule with root exudates (SAGE) inoculum were prepared, and their spore productions were compared with a soil inoculum. When the SAGE was used as the inoculum on sucrose-agar medium plates the number of spores was increased (35% more than the soil inoculum). After the soil inoculum and SAGE were inoculated on an experimental plant, Zingiber officinale, the percentage root colonization, number of VAM spores, and dry matter content were analyzed. It was observed that the SAGE showed a higher percentage of root colonization (about 10% more), and increases in the number of spores (about 26%) and dry matter (more than 13%) for the two VAM fungal spores than the soil inoculum. The results of this study suggested that the SAGE inoculum may be useful for the mass production of VAM fungi and also for the large scale production of VAM fungal fertilizer.

  • 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.

  • An experiment was carried out to investigate the effects of pre-inoculation with the mycorrhizal fungus Glomus clarum and foliar application of kinetin on the growth of mungbean plant irrigated wht different dilution of seawater. Arbuscular-mycorrhizal(AM) infection significantly increased dry weight, height, chlorophyll, sugar and protein content, nitrogen and phosphorus-use efficiencies, leaf conductivity, transpiration rate, nitrogenase, acid and alkaline phosphates activities of all salinized mungbean plants in comparison with control and non-mycorrhizal plants irrespective of the presence or absence of kinetin. Mycorrrhizal plants showed higher concentrations of N, P, K, Ca and Mg and lower Na/N, Na/P, Na/K, Na/Ca and Na/Mg ratios than non-mycorrhizal plants when irrigated with certain dilution of seawater. Mungbean plants showed 597% and 770% dependency on AM fungus G. clarum in absence and presence of kinetin, respectively, for biomass production under a level of 30% of seawater. The average value of tolerance index for mycorrhizal plants accounted 267% and 364% in absence and presence kinetin respectively. This study provides evidence for the benefits of kinetin which are actually known for mycorrhizal than non-mycorrhzal plants. AM fungus and kinetin protected the host plants against the detrimental effects of salt. However, mycorrhizal infection was much more effective than kinetin applications. Thus management applications of this arbuscular mycorrhizal endophyte(G. clarum) with kinetin could be of importance in using seawater in certain dilution for irrigation in agriculture.

  • This study was to investigate the origin of meridian through the relationship between Five Su Points and arteriovenous anastomosis. We searched traditional studies about origin of merdian and papers on relationship origin of merdian and blood vessels. As bibliographic search results, we got the conclusion that it is funtion of arteriovenous anastomosis and its anatomical position. Next we compared relationship between it and merdian. We found that Jeong-Acupuncture Points of Five-Su Points and Geun-Acupuncture Points of merdian have close relate to anatomical position(similarities). When we compared relationship between arteriovenous anastomosis and hypertension, we found that Biao Acupuncture Points and Geun Acupuncture Points of merdian have close relate to regulation of blood pressure and blood circulation. According to this results, Five Su Points and arteriovenous anastomosis have close relationship in anatomical position and regulatory function of blood pressure.
