Wild ginseng production is increasing due to forest recovery for last 30 years. Total number of Symmani (traditional mountain ginseng digger) was 558 in 2001. Provincial distribution of Symmani in 2001 was highest in Kangwon $(32\%),$ next in Choongbook $(21\%)$ and least in Jeonnam $(0.7\%)$ and Kyoungnam $(0.9\%).$ Age distribution of Symmani was $33\%\;for\;fourties,\;32\%$ for fifties and $20\%$ for sixties. There were 8 persons in eighties. Symmanies are still keeping traditional ritual for mountain god serving clothes of colored ribbons and foods. Increased production induced open market system from underground dealing of mountain ginseng. Korea Mountain Ginseng Association established mountain ginseng assessment committee with professional Symmanies in 2001. From September to November in 2001, 987 roots were requested for quality assessment to the committee and 476 roots $(48\%)$ were passed and graded and others were rejected. Highest frequency of rejection was foreign origin. Pass rate was highest $(74\%)$ in Choongnam suggesting best place for quality. Number of collected roots in each province was positively correlated (p=0.05) with number of Symmanies. There are 3 quality groups of mountain ginseng, Heaven (pure natural), Earth (from seeding of wild ginseng) and Man (from seeding or seedling of wild ginseng with slight environmental modification). The relationship between price and age was polynomial in high quality root, Heaven, Earth and seed long head of Man group, and linear in low quality group, seedling long head of Man. The best one in 2001 was 26 g, 124 years old and sold with 109 million won. Quality criteria are age, shape, weight, color and healthy outlook. Fine roots are criteria for health status of roots and taproot is criteria for efficacy and called as medicine barrel. The implication is that ginsenosides have rarely been experienced for efficacy. The quality criteria of cultivated ginseng were originated from those of mountain ginseng. It is unique for mountain ginseng that only fresh one can be on market. Since quality criteria of mountain ginseng must be based on the efficacy experience it is well expected that present criteria might almost be established at the age of Shinnong Materia Medica.

Root-rot of ginseng caused by Fusarium solani is one of the most obstacles to ginseng cultivation. We evaluated some inoculating techniques of ginseng with Fusarium solani, for selection of disease resistant breeding lines. The most effective inoculating techniques evaluated were inserting toothpicks colonized by F. solani into the seedling roots in laboratory test and dusting seedlings with vermiculite after dipping in conidial sllspension and then replanting method in field test. The resistance to diseased by F. solani was lines of 82022 and 82066 in laboratory test. 82920-1 and 78093 in field test.

본 실험은 품종별 종자의 크기가 묘삼의 소질에 미치는 영향을 조사하고 우수한 묘삼생산의 기초자료로 삼고자 수행하 였다. 품종간 종자크기별 개갑율과 생존율을 조사한 결과 개갑율은 품종에서 선운이 가장 우수하였고, 천풍의 개갑율이 가장 불량하였다. 종자크기는 개갑율 과 생존율에 영향을 미치지 못하였다. 경장, 경직경, 엽면적은 종자의 크기가 클수록(4.7 mm 이상) 생육이 우수하였으며 종자의 크기가 작을수록 생육이 불량하여 지상부 생육에 종자의 크기가 영향을 미치는 것으로 확인되었다. 근장, 근직경, 근생체중은 종자의 크기가 큰 것(4.7 mm 이상)이 생육이 우수하였으며, 종자의 크기가 작은 것은 생육이 불량하였다. 종자크기별 이용가능 및 불용묘삼을 조사한 결과 종자의 크기가 클 수 록 이용가능 묘삼의 수량과 본수 증가하는 경향이었다. 품종에서는 연풍, 금풍, 고풍이 지상하부의 생육이 우수하였으며, 천풍은 지상하부의 생육이 낮았다. 사용가능 및 우량묘삼을 생산하기 위하여 4 mm이상의 종자만을 파종하여야 할 것으로 생각된다.

Good quality seedlings produced in the seedbed of Yangjik, traditional seedling cultivation, is one of the most important factors in determining the yield and quality of $4{\sim}6-year-old$ ginseng. This study was carried out to substitute Yacto, traditional organic fertilizer, for economical compost in the cultivation of seedling by fertilizing relatively little amount of compost into seedbed soil. Bulk density and solid phase were decreased in physical properties of seedbed soil, while air phase and porosity were increased by more addition of compost. When the amount of applied compost in seedbed soil was above $8{\ell}$ per Kan, the contents of nutrient were exceeded the range of optimal standard for ginseng cultivation. Chlorophyll content and stem length were increased by more addition of compost, while the length and the width of leaves showed the highest value at the application level of $8{\ell}$ per Kan. Heat injury was also increased distinctly above the application level of $8{\ell}$ per Kan. The number of first grade seedlings and usable seedlings, and fresh root weight per plant showed the peak at application level of $8{\ell}$ per Kan, respectively. Fertilizing the compost of $8{\ell}$ per Kan into seedbed soil was the optimal amount for producing the good quality seedlings.

왕겨부초와 피트시용한 묘포(苗圃)에서 묘삼수량(苗蔘收量)은 토양수분(土壤水分)에 의존(依存)하였으며 이 의존도는 토양칼리가 감소할수록 증가하였다. 부초와 피트처리는 토양수분을 증대시켰다. 수량의 토양수분 의존도에 대한 칼리의 영향은 일정수분 범위에서 일정할 것으로 보이며 이 수분범위는 묘삼생육의 적정수분 범위일 것 같다. 수량과 토양수분의 편상관계수 유기물, Mg, Ca에 관하여 유의성이 있었다. 수량에 관한 최적 다중(多重)회귀는 수분, K, Ca,의 조합이었다. 토양유효인산은 부초에 의하여 증가되고 피트 저수준에서 증가되나 고수준에서 감소되었다. 토양수분, pH, Ca, Mg, K, OM의 두 요인 간에는 K와 수분 또는 pH관계를 제외하고 직선유의상관이 있었다. 암모니아태질소는 Mg와 부 상관이었다. 질산태질소와 K 또는 $NH_4-N$간에 그리고 P와 K+Ca+Mg간에 2차회귀관계가 있었다. 토양요인 간에는 직선관계보다 2차회귀관계가 유의성이 컸다. 부초는 경장을 증가시켰으며 엽면적지수는 1.06~1.67범위였고 묘당엽 면적은 $16.0cm^2{\sim}18.8cm^2$범위였다.

The causal organism of Phytophthora disease on Panax ginseng Meyer in Korea was isolated and identified as Phytophthora cactorum. It's pathogenicity, etiology, and possible control measures were investigated. Disease symptoms on various parts of ginseng plants were also described The fungus caused seedling and mature plant blight and root rot. Oospores were easily formed on potato dextrose agar and corn meal agar. Oospores, however, were not formed in the diseased root tissues but did in the in footed shoots such as leaves, petioles, and stems and in the inoculated berries.

Freshly harvested, immature (green) seeds of North American ginseng (Panax quinquefolius L.) were stratified for up to 3 years in plastic pails in controlled environment rooms at $5{\pm}1^{\circ}C$ for 9 months and then $21{\pm}2^{\circ}C$ for 3 months (Trt. 1, regular stratification), or continuously at $-2{\pm}0.2^{\circ}C$ (Trt. 2), or continuously at $3{\pm}0.2^{\circ}C$ (Trt. 3). During stratification at -2 and $3^{\circ}C$ embryos did not grow. On seeding in the field embryos grew rapidly and resultant seedlings were comparable to those from regularly stratified seed. Seedling emergence rate was acceptable at the industry expected rate of 68% after one year of storage, but not after two years storage when it declined to 17.5%. Seed rot was so severe in year 3 that no planting was carried out. Seedling and second year growth were similar at the three stratification temperatures; most importantly, root dry weight (economic yield) was similar. Low-temperature storage of freshly-harvested North American ginseng seed is an acceptable method for short-term retention of propagating material.

Rice hull was reduced to ash by carbonization grades to illcuidate alkalinity increase and extract of inorganic nutrients in the rice hull charcoal. Alkaline reaction of water extraction was neutral at less carbonized charcoal, but much carbonized ash from 65% weight loss reached over 10 of pH value, also origin shape of rice hull was maintained until near 65% carbonized grade. Therefore, physical properties sustained good condition for seedling bed. The more charcoal carbonized to ash, the pH value and concentration of inorganic nutrient in their extracts were increased gradually. Nitric acid concentrations for neutralizing extract from charcoal were stronger in proportion to the carbonized grade but 0.1 N nitric acid solution was very reasonable to neutralize the 65% carbonized charcoal for mixing with heavy texture acidy soil(pH 5.3) of uncultivated deep horizon to transplant the tobacco seedlings. Volume ratio mixing for seedling bed is adequate at five of ash to one of acid solution. Neutralization with nitric acid solution also accelerated extraction of the inorganic nutrient in rice hull ash. Tobacco seedlings grown on bed mixed with neutralized rice hull charcoal and soil had shown better results on the agronomic measurement than alkaline ash bed, and phosphorus and cations were uptaken more amounts.

본 시험은 인삼비료인 약토를 대체 하기 위하여 인삼비료인 약토 외에 4종의 퇴비를 공시하여 약토 대체 가능성을 검토하였다. 퇴비종류별 식부가능묘삼의 생산량은 약토>PL퇴비)팽이버섯퇴비 >볏짚우분퇴비>HJ퇴비 순으로 약토가 가장 우수하였다. 퇴비종류별 묘삼중의 무기성분 함량은 약토구는 타 퇴비구에 이해 잎과 줄기에서 칼슘함량이 높았으나 뿌리에서는 차이가 없었으며, PL퇴비구는 잎과 줄기에서 질소함량이 다소 높게 나타났다. HJ퇴비는 잎에서 인산과 카리의 함량이 높았고, 경에서 인산이, 뿌리에서 질소의 함량이 높았고, 팽이버섯퇴비는 잎과 줄기에서 질소와 마그네슘함량이 높았고, 뿌리에서는 마그네슘함량이 높았다. 볏짚우분퇴비는 줄기에서 질소, 카리, 마그네슘 함량이 높았고, 뿌리에서 인산, 카리 함량이 높았다. 우량 양직묘 생산을 위해서는 완숙된 퇴비를 사용하여야 하며, PL퇴비와 팽이버섯퇴비는 약토 다음으로 식부가능 묘삼 생산량이 많아, 완숙시킨 후 재검토가 필요하다.
