This study was conducted to find out the optimum composition of nursery soil for raising seedling of ginseng (Panax ginseng C. A. Meyer). Total 9 kinds of raw materials were used such as peat-moss, perlite, leaf mould, rice bran, gull's guano, castor-oil plant bark, palm bark, cow manure and chicken manure for optimum composition of nursery soil in ginseng. Occurrence of damping-off in ginseng was lowered about 50% in nursery soil type 1, 2 and 4 than in other types nursery soil in June, and occurrence rate of rusty root also lowest in nursery soil type 1. As the salinity of nursery soil increased, so did the occurrence of physiological disorder in ginseng seedling. The cause of salinity increasing in nursery soil has closely relation to $NO_3-N$, $P_2O_5$ and $Na^+$ content. Plant height, root length, diameter and weight were longer and heavier in nursery soil type 1 (mixing ratio of peat-moss, perlite and leaf mould was 50 : 20 : 30 based in volume) than in other types of nursery soil. So nursery soil type 1 was selected for raising seedling of ginseng. pH and electric conductivity (EC) of selected nursery soil type 1 was 5.55 and 0.13 dS/m. Contents of $NO_3-N$ and $P_2O_5$ were 21.0 and 40.0 mg/L, and $K^+$ 0.36, $Ca^{2+}$ 3.38, $Mg^{2+}$ 2.01 and $Na^+$ $0.09cmol^+/L$, respectively.

To control the disease of root rot in ginseng nursery, inorganic sulfur solution of 0.1%, 1.0%, and 2.0% were irrigated by amount of $10{\ell}$ per $3.3m^2$ before sowing. On the last ten days of July, Fusarium solani and F. oxysporum were similarly detected by 44.8% and 43.8%, respectively, while Cylindrocarpon destructans was low detected by 4.4% in the diseased seedling. The more sulfur's concentration was increased, the more soil pH was decreased. Soil pH was decreased from 5.87 to 4.59 by the irrigation of sulfur solution of 1.0%. The more sulfur's concentration was increased, the more electrical conductivity (EC) of soil was increased. EC was increased from 0.27 dS/m to 1.28 dS/m by the irrigation of sulfur solution of 1.0%. Irrigation of sulfur solution was effective on the inhibition of damping-off caused by Rhizoctonia solani in ginseng seedling. Control value for damping-off by the irrigation of sulfur solution of 1.0% and 2.0% were 75.7%, and 78.5%, respectively. Growth of leaf was inhibited by the irrigation of sulfur solution of 2.0%. Root weight per $3.3m^2$ showed the peak in sulfur solution of 1.0%, while survived-root ratio and root weight per plant were decreased in the level of 2.0%. Survived-root ratio of seedling in sulfur solution of 1.0% was distinctly increased by 4.7 times compare to the control, but control value for root rot was relatively low as 49.2%. Mycelium growth of C. destructans, F. solani, and R. solani were distinctly inhibited by the increase of sulfur's concentration in vitro culture using PDA medium.

비닐하우스 내에서 일평균 투광율을 21.2%, 24.8%, 30.3%와 같이 3수준으로, 토양수분을 11.0%, 12.5%, 15.3%, 18.9%와 같이 4수준으로 조절하여 묘삼의 생육 및 수량을 조사한 결과는 다음과 같다. 엽록소 함량은 투광율이 낮은 조건에서 토양수분함량의 감소에 따라 완만히 감소되었으나 투광량이 높은 조건에서 토양수분함량이 낮아지면 엽록소 함량은 현저히 감소되었다.고온장해율은 투광율이 낮은 조건에서 토양수분함량이 11.0%처럼 매우 낮을 때에만 현저히 증가되었지만 투광량이 높은 조건에서는 토양수분함량의 감소에 따라 고온장해율은 급격히 증가되었다. 3.3$m^2$(칸)당 생근중, 주당 생근중 및 사용가능묘삼수는 투광율이 증가되고 토양수분함량이 감소될수록 뚜렷이 감소되었는데, 토양수분함량이 적절한 조건(18.9%)에서는 투광율이 증가되어도 묘삼수량의 감소는 적었으나 토양수분함량이 부족한 조건에서는 투광율이 증가될수록 묘삼수량은 현저히 감소되었다. 적변율은 투광율이 높고 토양수분함량이 많을 때 현저히 증가되었는데, 투광율이 높은 조건에서 토양수분함량이 감소되면 적변율도 차차 감소되었으며, 투광율이 낮은 조건에서 적변율은 토양수분함량에 따라 큰 변화를 보이지 않았다.

To know possibility of raw ginseng production for white- and red-ginseng by direct-sowing culture, seeds were directly sowed or seedlings were transplanted at soil condition of sandy loam in ginseng field. After cultivation, the characters of 5-year-old ginseng were investigated. Number of survived plants was increased with increase the seeding quantity in direct-sowing culture, the survived plants in direct-sowing culture was higher than that of transplanting one. Rate of the numbers of survived plants to numbers of seeds sowed in plots of 134 or 90 seeds sowed per tan, 180 x 90cm area, inspire of high number of survived plant was high compared to that of transplanting culture. Occurrence rate of rusty root of ginseng in direct-sowing culture was low significantly compared to that of transplanting culture. Root yield showed in the order of 134, 268, 90 seeds sowed, the values of yield in direct-sowing culture were high obviously compared to that of transplanting one. Individual root weight was increased with decrease the seeding quantity, however, the root weight in plot of 90 seeds sowed showed almost equal the weight in transplanting culture. The number of usable raw ginseng for white- and red-ginseng was increased with decrease of the seeding quantity; the numbers were higher than that of transplanting culture remarkably. We concluded that optimum seedling rate in direct-sowing culture of ginseng was 90 to 134 seeds per tan considering the yield per area and production rate of large root.

임간의 자연 방임 상태 하에서 인삼의 종자 및 묘삼을 직파 또는 1년근 묘삼으로 이식했을 때와 묘령별로 이식했을 때 년차별 생존율 및 생육 변화를 일반재배 인삼의 생육과 비교 관찰한 결과는 다음과 같다. 가. 5년 동안 년차별 인삼의 생존율은 직파재배의 경우 파종 이듬해에는 침엽수림과 일반재매에서는 높았으나, 활엽수림에서는 낮았으며, 년차별로 급격히 감소하였다. 그러나 1년생 묘삼을 이식 재배한 경우는 일반재배보다 오히려 생존율이 좋았고, 이식 후 시간이 경과하면서 어느 정도 생존율이 감소하고는 있으나, 직파재배에 비해 상대적으로 감소되는 폭이 적었다. 나. 인삼 직파 및 1년근 묘삼 이식재배 시 지상부 및 지하부 생육은 임간의 직파재배, 이식재배 모두 일반재배에 비하여 생육이 크게 저조하였고, 침엽수림과 활엽수림 간에는 차이가 없었다. 다. 임간에서 인삼 묘령별 생존율은 $1{\sim}6$년근 모두 일반재배와 비슷하거나 우수하였지 만 $4{\sim}5$년근은 $1{\sim}3$년근에 비해 이식당년부터 생존율이 낮았고, 년차별로 생존율이 급격히 떨어지는 경향을 보였다. 라. 묘령별 지상부 및 지하부 생육은 1, 2년근의 경우 임간에서 일반재배에 비해 발육속도는 느리지만 임간재배와 일반재배 모두 생육이 양호하였으나, $3{\sim}6$년근까지는 발육이 정지하거나 오히려 줄어들었고, 묘령이 많을수록 생육이 불량하였으며, 특히 일반재배에서는 임간재배보다 생육이 더욱 불량하였다.

Ginseng seeds were gathered from 3,4,5 and 6 years of age and were classified into four qroups (below 4mm, 4∼5mm, 5∼6mm and above 6mm in across sieve). They were sown in seedling bed and some characters were investigated in each qroup of seed size. 1. The distribution of seed size of below 4mm, 4-5mm, 5-6mm and 6mm were 23.7%, 60.8%, 12.4% and 4.5%, respectively. 2. The ratio of seed coat dehiscence was not affected by seed size but emergence ratio and emerging vigor were superior in large seed. 3. The large seed showed superiority in stem length, stem diameter, leat and also in root length, root diameter and root weight. but diseased root was not affected by seed size. The effect of age(seed harvest) was not significant on all those characters.

저년생 인삼의 잠아 및 화기형성시기와 양상은 고년생 인삼의 이차적인 양상과 상이하기 때문에 1년생 묘삼의 잠아발달 및 다식된 2년생 인삼의 화기형성과정을 조사관찰하였던 바 그 결과를 요약하면 다음과 같다. 1. 2년생 이상의 인삼 잠아조직은 4월중순경 분제조직의 조기포분제로 시작하는데 1년생 묘삼에서는 유근발근시인 3월 하순경 시작하는 것으로 추측되었으며 잠아의 위치는 자엽간 줄기하단 문부위에 생성되었다. 2. 3년생 이상의 인삼 화기분화는 전년도 형성된 뇌두조직내에서 형성되지만 2년생 인삼의 화기는 줄기선단 엽병사이의 경단분제조직에서 분제세포의 분열과 함께 분화, 형성되었다.

Incidence of damping-off callsed by Rhizoctonia solani was 0.6-10.9% at "Yangjik" seedbed in Pocheon, Korea. The seedbeds where the lengths of etiolated stems (underground portion) of ginseng seedlings were 0.78-1.25 cm showed 0.8-3.2% of the disease, while 6.9-10.9% disease incidence was observed at the seedbeds with the longer etiolated stem (1.89-2.26 cm). The pathogen produced a typical girdle symptom on the etiolated portion of ginseng stems close to the soil surface. The deeper the seeds were sown, the more the disease occurred in pot soil inoculated with the pathogen, AG 2-1, showing 18.4, 27.4 and 32.9% of damping-off at the seeding depth of 1, 2 and 4 cm, respectively. Cuticle layers of colored stems (over ground portion) were well - developed to be 42.8, 58.0, and 55.0 um in thickness compared to the etiolated stems with 8.5, 15.0 and 8.0um for seedling, 2 year-old, and 3 year-old ginsengs, respectively, when the disease occurred. In the seedling and 2 year-old ginseng, the colored stems were more rigid than the etiolated. There was however, no difference in rigidness of the stem of the 3 year-old ginseng where the disease is not severe as in seedlings and 2 year-old ginseng plants.ng plants.
