  • This study was conducted to elucidate the growth characteristics and change of inorganic element in the leaf of perilla by replanting. The replanting injury in the height of perilla appeared from the 2nd and 3rd year after replanting, and the sickness of soil occurred from the 4th year. Number of node of perilla by replanting was significantly affected to the middle stage of growth, but was similar at the latter stage of growth. Weight of a leaf was the highest at the 1st and 2nd year, and decreased with the replanting. Also, the rate of dry leaf decreased with the replanting. In the content of inorganic element of the perilla leaf by replanting, N in the leaf increased with the replanting, and K and S decreased. However the content of Ca, Cu and Mn did not affected to replanting.

  • This study was carried out to examine the tree-ring growth characteristics of Zelkova serrata Makino after replanting, for the built-up planting founds for stability of landscaped trees in the reclaimed land from the sea. the factors, many affecting the growths of Zelkova serrata Makino, were the replanting stress and drought. The growth reduction due to replanting and drought occurred in the replanting year and the following year. The mean sensitivity(year-to-year variation) and the coefficient of variation(tree-to-tree variation in a certain year) in tree rings of Zelkova serrate Makino, were higher in the poor soil sites than in the favourable soil ones. And the poor soil sites were the filled ground of improve soil and the covered ground of improve soil and the top ground of big mounding than mounding ground sites, especially soil hardness, alkali soil, high $Na^+\;and\;K^+,\;low\;Ca^{++}\;and\;Mg^{++}$ and T-C were the most crucial. We suggest technique development of the built-up planting ground for stability in the reclaimed land from the sea. The built-up planting grounds in reclaimed land from the sea, should be considered for the use of fair soil with the physical and chemical soil properties, -high level foundation of planting ground, and the prevention of disturbed soil-.

  • 본 연구는 광양만 임해매립지의 곰솔 식재 이후 연륜생장에 영향을 미치는 식재환경과 기후요인을 조사 분석하였다. 임해매립지의 곰솔 식재 이후에 수목의 이식과 가뭄에 의하여 연륜생장이 급감소하였다. 수목이식에 의한 연륜생장의 급감소는 모든 지반들에서 유사하게 나타났다. 가뭄에 의한 연륜생장의 감소는 토양경도가 높은 식재지반에서 급격하게 감소하였으나 성토지역에서는 감소 현상이 크지 않았다. 이식에 의한 연륜생장 급감소 이후에 토양경도가 높은 지반들에서는 생장회복이 저조하였으나 성토지역에서는 빠르게 생장이 회복되었다. 연륜생장의 평균민감도와 상대적 변이계수는 토양경도가 높은 지반들이 성토지반들보다 높게 나타났다. 이것은 토양환경이 불량한 지반일수록 외부적 환경변화에 대하여 불안정적으로 생장하는 것으로 해석되었다. 이상의 결과를 요약하면 곰솔의 연륜생장은 이식과 가뭄에 대하여 성토지반에서는 수목 자체적으로도 양호하게 생장을 하지만 토양경도가 높은 지역에서는 생장이 불량하였다. 따라서. 외부적 환경변화에도 수목자체적으로 적응할 수 있는 식재 및 유지관리 방법이 모색되어져야 할 것으로 사료되었다.

  • There are many existing trees are to be damaged by reconstruction of large housing estates. The purpose of this study was to find out sustainable conversion methods of Greenbank system by UR Agency. Greenbank system is divided 3 parts as Preserving, Replanting, Recycling of Existing trees. Literature and institutional review and site survey of 5 reconstruction housing estate were the methods for the following findings. The results are follows. Firstly, Because of feasibility of reconstruction, existing trees are preserving at boundary space of reconstruction housing estates. Secondly, existing trees are preserving at inner space for remember of resettlement as symbolic trees. It is conformed by residents participation with UR Agency and city official. Thirdly, Preserving and replanting trees are recorded signboard in the reconstruction housing estates, and preserving of trees are developed as Green workshop by residents. Fourthly, Besides Preserving and Replanting trees, the other trees are recycling as bench, play equipment, planter, etc. And it is remained symbol of reconstruction housing estates. Fifthly, District planning as a institutional, Guidelines as a noninstitutional method are very efficiently for preserving trees. But a part of this study can be adapt reconstruction housing estates in Korea. The results of this study are expected to serve some clue for dealing with the practice of sustainable conversion in housing estates.

  • Effect of gibberllin on the breaking of bud dormancy of root and growth of aerial parts were investigated under laboratory and field condition for the prolongation of shoot growth duration, shortening of fruit bearing age and the increase of root yield. Drop application of GA (0.5ml of 50ppm) on rhizome of one year old root broke bud dormancy better than by low temperature. Soaking for one hour of one year old roots which wintered in the field in GA (50-200ppm) greatly accelerated the emergence of new buds while kinetin was only effective at low level (50ppm). GA substantially increased stem length in early stage and petiole length later on while kinetin increased stem diameter. Under the field condition with polythylene film tunnel (PET) in early spring the soaking in GA (50ppm for 1 hour) of rhizome of 4 year old root with replanting and dropping GA (50ppm, 1ml) on rhizome without replanting brought earlier emergence (29days) in comparison with that in the usual field. PET alone caused 14 day-early emergence. GA increased the length of stem and petiole only in early stage and replanting decreased only petiole length in later stage. Soaking in GA with replanting caused the Pronounced decrease in peduncle length, percentage of (ruin set and dry weight of reproductive organ (fruits and peduncle). Dropping without replanting showed significant decrease only in dry weight of reproductive organ. Fruit maturing was 20 days earlier than in usual held with little difference between GA and PET. It is well expected that GA could be used for early emergence of bud, shortening of root dormancy period, thinning of fruit and higher root yield according to application amount and methods.

  • How far of natural regeneration of the city and improvement on the urban environment will be possible in the replanting on the impermeable surface? The replanting of what kind of form will be obtained in order to realize it? The regeneration of the nature is possible, if it can be realized at the thin soil layer in which the result of being equivalent to the natural soil function. Using the light artificial soil with the water retentiveness, it is possible that green on the artificial ground reinforces the green skeleton of the city. The green of artificial ground improves the thermal ambience of the city and demonstrates stormwater runoff depression effect. It is necessary to built the landscape which continues with the surrounding green. Ecologically stabilizing green has the high amenity. The development of replanting technology of the artificial ground which fosters the city culture is desired.

  • 인삼의 연작장해의 증상, 원인 및 방제법에 대하여 고찰하였다. 1. 연작장해의 증상은 인삼의 생장억제 근부에 의한 근수량 저하였으며 품질에는 영향을 주지 않았다. 2. 연작장해는 토양병원미생물과 인삼유체 분해산물의 식물에 대한 직접적인 독작용, 그리고 이들 유체 및 그 분해산물에 희한 토양내 전속화합물의 용해 또는 결합에 따른 전속이온의 식물에 대한 독작용 등이 상호 복합적으로 나타난 것으로 보인다. 3. 토양은 근부유발형과 근부억제형 토양으로 구분되며, 토양이화학성이 연작장해를 조장시키지는 않았다. 4. 연작장해의 방제법은 살균제에 의한 효과는 기대하기 어렵고, 훈증제(싸이론, 크로로피크린)를 처리하여 연작할 경우 고년근에서 근부병 발생이 심하기 때문에 훈증제와 길항미생물의 혼합처리가 효과적이다. 또 답전윤환이 가능한 논에서 3∼4년간 벼를 재배한 후 인삼을 연작하는 방법이 실용화되고 있다.

  • The disease development of root-rot [pathogen:Cylindrocarpon destruction (Zinssm.) Scholten] occurred in 2-year old ginseng (Panax ginseng C.A. Meyer) was investigated in the continuous (the first cultivation: 1978∼1982, 2nd cultivation: 1990∼1993 and abolished in 1993 due to replanting problem) and replanted cultivation (period of cultivation: 1980∼1984). In the continuous cultivation, incidences of root-rot were 0.7% on May 3, 48.6% on May 24, and 95.8% on June 14, respectively. In the replanted cultivation, no symptom was observed on May 3 and disease incidence was generally lower compared with the continuous cultivation. On the aerial part of the ginseng infected by C. desiccates, the end and/or margin of leaves were changed to dark reddish color that appeared for behind the root-rot symptom. In this field, the longitudinal growth of lateral root was more inhibited than in the case of the replanted cultivation by C. destmctans. The inhibition rate of rootlet growth was 37.3% in the continuous cultivation as compared with that of replanted cultivation at June 14. Though lesions of root-rot were formed all over the roots, 61.2% of the lesions was positioned within 6 cm under the rhizome. Key words Panax ginseng, Cylindrocarpon destmtan, root-rot of ginseng, replanting problem of ginseng.

  • Background: Rehmannia glutinosa is a perennial herb belonging to the family Scrophulariaceae and is used in traditional oriental medicine. This study was conducted to evaluate the appropriateness of plug-seedling cultivation for replanting of R. glutinosa. Methods and Results: The seed rhizomes of Rehmannia glutinosa 'Jihwang 1' were harvested in the middle of March, 2018. Direct seedling cultivation was conducted after air curing for 3 days. The seedlings for transplanting were cultivated for 30 (30D), 45 (45D), and 60 days (60D). The mat formation rates of the 30D, 45D and 60D treatment seedling were 81.3%, 100%, and 100%, respectively. Of the tree treatment groups, flowering occurred only in the 45D and 60D treatment groups, and their flowering rates were $7.3{\pm}3.06%$ and $13.3{\pm}1.15%$, respectively. The agronomic characteristics and active components of the three treatment groups were evaluated in comparison with the DS1 (directly seeded group, control) and DS2 (directly seeded group, replanting) groups. As a result, the leaf length and leaf width of the 30D seedlings were higher than other treatment groups, but the number of leaves per plant was statistically the same. In addition, root diameter and yield of the 30D seedling were statistically the same as DS1. Moreover the catalpol contents of 30D, 45D, DS1 and DS2 group seedlings were 2.23%, 1.86%, 2.50% and 2.08%, respectively. Conclusions: Taken together, these findings suggest it is feasible to use the plug-seedling cultivation method for replanting of R. glutinosa. seedlings. However, further evaluation of the economic aspect is needed.

  • 인삼 뿌리썩음병의 발생을 경감시키기 위한 효과적인 담수조건을 확립하기 위해, 실험실 조건에서 인삼 재작지토양을 공시하여 인위적으로 담수처리하고, 담수전 유기물의 첨가 여부 및 담수후 처리온도가 토양내 Fusarium 을 비롯한 사상균과 세균 밀도에 미치는 영향을 조사하였다. 담수처리를 하였을 때 토양내 Fusarium 및 총사상균 밀도는 시일이 경과할수록 감소하였고, 담수에 의한 균밀도 감소효과는 온도가 높을수록 증가하였고, 또한 동일 온도조건에서 유기물을 첨가하였을 경우에는 그 효과가 더욱 증대하였다. 즉, 3$0^{\circ}C$ 조건에서 유기물을 첨가하지 않았을 경우 처리 60일후의 균밀도가 무담수 토양의 1/10 수준으로 감소하였던 반면, 유기물을 첨가하였을 경우에는 1/100 수준으로 감소하였다. 유기물 종류별로는 볏짚 처리효과가 청초에 비해 더 높았다. 한편 담수토양에서 총세균의 밀도변화 경향은 사상균의 경향과 유사하였으나, 담수에 의한 세균밀도 감소효과는 사상균에 비해 낮았다. 이상의 결과에서 인삼재작지 토양에 유기물을 첨가하고 포화상태로 담수한 후 3개월 이상 수온을 3$0^{\circ}C$이상 유지할 경우 뿌리썩음병 발생을 보다 경감시킬 수 있을 것으로 사료된다.
