When medicinal mushroom, Poria cocos, is cultured , inoculation method of spawn is cross slice inoculation of which the both sides of pine tree were peeled and spawn of P.cocos was inoculated. However, this method required lots of inoculation amount. This study was carried out to improve the culturing method of P. cocos. A good growth of P.cocos was observed in MCM(mushroom complete medium), showing proper mycelia growth and density. In inoculation amount, conventional method(cross slice inoculation) requires 20 bottles of spawn. In contrast, short log method required 8 bottles of spawn and drilling inoculation method 2~3 bottles, which could save by 60% and 85-90% respectively. In the selectrion of tree species, pine and larch had better condition for spawn culture and sclerotia formation condition.In terms of yield , pine was 33.7kg/3.3$m^2$. In the yield of pine, conventional method was 23.4kg/3.3$m^2$, drilling inoculation 29.4kg/3.3$m^2$, short log inoculation 31.7kg/3.3$m^2$, therefore drilling inoculation could increase by 25% and short log inoculation 35%, In addition, management cost was also saved.

Effect of inoculum concentration inoculation method and plant age on development of clubroot disease of Chinese cabbage seedling were examined in growth chambers. Root galls were developed at the concentration of 105 resting spore or above per ml of incoulum and as the inoculum concentration became higher rate of development of root galls was faster. In the plants with root gall development fresh weight of above ground parts was reduced to 30-44% of that of healthy plants but root weight increased by 4-10 times. Growth of diseased plants was greatly reduced as compared to healthy plants. Planting in the diseased soil as a inoculation method was most effective for disease development showing uniform infections but time of initial root gall development was delayed by root soaking inoculation. Some plants inoculated by soil drenching method did not develop root galls. However root gall enlargement after its initial formation did not differ greatly among inoculation methods. Nine-day-old seedlings showed poor development of root gall but 16-days-old seedlings was found to be most adequate for inoculation for gall development.

Three kinds of inoculation methods, capillary, root cutting and dipping were compared for an efficient way to screening the resistant tobacco variety against bacterial wilt, Ralstonia solanacearum. The pricking a capillary tube contained the pathogenic bacterial suspension(10$^{7}$ cfu/$m\ell$) to an axillary bud of each tobacco plant showed different resistance well between varieties. The less period was required in inoculating work and in disease development for the inoculation method used with capillary tube than for two other inoculation methods tested also.

Information on the effective application method of arbuscular mycorrhizal fungi (AMF) inoculum is still inadequate. This work was performed to assess two AMF inoculation methods (dispersed and proximate) on root colonization of sorghum-sudangrass hybrid (Sorghum bicolor L.). In dispersed inoculation method, spores were inoculated in 2 kg pots of soil in which 5 day-old seedlings were transplanted and maintained for 50 days. In the proximate inoculation method, spores were first introduced in 500 mL pots where seeds were sown. After 10 days, the seedlings with the 500 mL soil were transferred to 2 kg pots without disturbing the contents. After 50 days of growth, root colonization and arbuscule abundance significantly increased (over 100%) in proximate method of inoculation. Moreover, sorghum-sudangrass hybrid had higher shoot growth (182.5 cm) and Glomalin related soil protein (GRSP) production in proximate method. Nutrient accumulation, particularly total nitrogen (82.61 mg $plant^{-1}$), was also found to be higher in proximate method of inoculation. Our results demonstrate that the proximate method of inoculation may improve the early stage mycorrhizal symbiosis and inoculum performance in Saemangeum reclaimed soil.

벼 흰빛잎마름병에 대한 새로운 포장 저항성 검정법을 모색하기 위하여 검정 식물체 접종법과 인접 식물체 접종법을 비교 검토하였다. 새로운 검정법인 검정 식물체 접종법에서는 포장 저항성 검정 식물체를 전엽접종한 발병엽으로부터 새로 출엽된 잎에 이차전염된 발병 엽면적율을 측정하였다. 검정 식물체 접종으로 검정된 포장 저항성 정도는 인접 식물체 접종 결과와 높은 상관이 인정되었으나 포장 저항성 정도는 검정 식물체 접종법에서 명확히 구분되었다. 공시한 33품종 중에서는 밀양 42호, 삼강벼, 태백벼, 한강찰벼, 섬진벼, 70 X-46, 중국 45호 등이 강한 포장 저항성을 보였다. 새로운 포장 저항성 검정법은 품종의 질적 저항성 및 포장 저항성을 동시에 검정할 수 있을 뿐만 아니라 다른 검정법에 비하여 노력과 포장 면적이 적게 들기 때문에 유용한 검정법으로 이용될 수 있을 것으로 생각된다.

This report described a simple, inexpensive, faster, and effective graft inoculation method for the artificial transmission of Mungbean yellow mosaic virus (MYMV). Success of grafting and disease transmission was 100％ in this method. Screening of mungbean germplasm using this method will prevent the chance of escape infection, probably as a consequence of non-preference mechanism and loss of vector infectivity. The grafting method described here is applicable to both screenhouse and field trials.

For comparison of mycelial colonization of Phellinus linteus on logs, several techniques of inoculation were tested; sterilized short log inoculation, drilling inoculation and log-end sandwich inoculation. The mycelial colonization of P. linteus on logs was good in the treatment of sterilized short log inoculation, but poor in the traditional methods such as drilling inoculation and log-end sandwich inoculation. The initial mycelial growth and the full mycelial colonization of P. linteus in logs were the best in case of 20 cm logs under the condition of 42% moisture content. Also, the initial mycelial growth of P. linteus was accelerated over 12 hours of sterilization. Burying method of logs after $5{\sim}6$ months of incubation was the best for formation of basidiocarps of P. linteus. The formation of fruiting body of P. linteus was quite good in the cultivation house at $31{\sim}35^{\circ}C$ and over 96% of relative humidity.

The purpose of the present work is to establish an ultra-minimal invasive percutaneous puncture inoculation method for a VX2 orthotopic lung cancer rabbit model with fewer technical difficulties, lower mortality of rabbits, a higher success rate and a shorter operation time, to evaluate the growth, metastasis and apoptosis of tumor by CT scans, necropsy, histological examination, flow cytometry and immunohistochemistry. The average inoculation time was 10-15 min per rabbit. The tumorbearing rate was 100%. More than 90% of the tumor-bearing rabbits showed local solitary tumor with 2-10 mm diameters after two weeks post-inoculation, and the rate of chest seeding was only 8.3% (2/24). The tumors diameters increased to 4-16 mm, and irregularly short thorns were observed 3 weeks after inoculation. Five weeks post-inoculation, the liquefaction necrosis and a cavity developed, and the size of tumor grew further. Before natural death, the CT images showed that the tumors spread to the chest. The flow cytometry and immunohistochemistry indicated that there was less apoptosis in VX2 orthotopic lung cancer rabbit model compared to chemotherapy drug treatment group. Minimal invasive percutaneous puncture inoculation is an easy, fast and accurate method to establish the VX2 orthotopic lung cancer rabbit model, an ideal in situ tumor model similar to human malignant tumor growth.

Since the leaf inoculation procedures are time-consuming and require considerable growth chamber space, a rapid dioassay method for screening of pathogenicity of Didymella bryoniae, a casual agent of gummy stem blight in watermelon, was established in this paper. The method produced reliable results within 8 days ( 5 days for growing seedlings and 3 days for rapid disease response in the seedlings). After contaminants in the root of 4~5 day-old seedlings had been washed using sterilized water, 5 seedlings were dipped into a vial containing 12 ml of conidial suspension (106 cells/ml). After the vials were placed in a growth chamber (22$^{\circ}C$, RH 50%, 14hr light/10hr darkness) for 3 days, susceptibility and resistance of cultivars were determined by the degree of disease response on cotyledon. The result of obtained by the dip-inoculation method was well coincided with the results by the leaf inoculation procedures and the result that had been observed for several years in the field. Screening of collected watermelon cultivars by the dip-inoculation method revealed that all the 21 domestic cultivars collected were susceptible and only 3 foreign cultivars (PI 189225, PI 482322 and IT 188207) were resistant among 18 cultivars A cucumber cultivar (Marketer) and bitter cucumber were proven to be resistant against the D. bryoniae among 8 other different cucurbits tested. The SDS-PAGE patterns of total proteins from a susceptible (Keumcheon) and a resistant (PI 189225) watermelon cultivars were compared 0, 12, 24 and 36 hrs after inoculation. The amounts of two distinct protein bands (24 kDa and 70 kDa) were gradually increased after inoculation in both cultivars.

Fusarium oxysporum f. sp. niveum에 의해 발생하는 수박의 덩굴쪼김병 저항성을 검정하기 위해 뿌리 침지 접종 방법이 많이 사용되어 왔다. 이 방법은 정확한 저항성 검정 결과를 제공하나 많은 노동력과 시간이 소요되어 보다 빠르고 효율적인 검정 방법이 요구되어 왔다. 본 연구에서 수박 덩굴쪼김병의 간편한 대량 저항성 검정법을 확립하기 위해 저항성 및 감수성 4개 품종의 유묘에 F. oxysporum f. sp. niveum을 네 가지 접종 방법(뿌리 침지, scalpel, tip 및 무상처 토양 관주법)으로 접종하고 덩굴쪼김병 발생을 조사하였다. 이들 중 scalpel 접종 방법은 실험 방법이 간단하고 정확한 저항성 반응을 보였다. 우리는 scalpel 접종 방법을 이용하여 수박의 생육 시기, 접종원 농도 및 접종 후 재배 온도 등의 발병 조건에 따른 위의 품종들의 덩굴쪼김병에 대한 저항성 반응을 조사하였다. 그리고 이들 결과로부터 확립한 scalpel 방법의 효용성은 시판 품종 23개의 덩굴쪼김병균에 대한 저항성 정도를 뿌리침지 방법과 비교하여 확인하였다. 이상의 결과를 종합하여 수박 덩굴쪼김병에 대한 간편 대량 저항성 검정 방법으로 수박 종자를 파종하여 온실에서 10-13일 동안 재배한 수박 유묘의 뿌리를 scalpel을 이용하여 상처를 준 후에 $3.0{\times}10^6\;conidia/ml$의 포자현탁액을 포트당 10 ml씩 관주하고 $25^{\circ}C$에서 하루에 12시간씩 광을 조사하면서 약 4주 동안 재배하는 것을 제안하고자 한다.
