The two-month-old rooted-cuttings of Populus albs × glandulosa, P. euramericana and P. nigra × maximowiczii clones were exposed to livestock waste water - one of major water pollutants, and ground water in order to determine the effects of livestock waste water on growth response and absorption capacity of the species. For this purpose, 5 clones of each species were used. In all the species, the height growth of rooted-cuttings was better in livestock waste water treatment than in ground water. Of all the poplar species compared, the height growth was best in P. alba × glandulosa. In the cases of P. euramericana and P. nigra × maximowiczii, the height growth in the livestock waste water treatment was statistically different among clones, whereas there was no significant difference among P. alba × glandulosa clones. Aboveground biomass such as leaf and shoot dry weight of all the species increased in the livestock waste water treatment, while root dry weight decreased. In addition, chlorophyll contents in leaf of all the poplar species increased in the livestock waste water treatment. All the poplar trees showed temporal variation in the absorption amount of livestock waste water during the experimental period. In all the poplar species, the absorption amount of livestock waste water was less than that of ground water. Of 3 poplar species, P. alba × glandulosa was best in the absorption capacity of livestock waste water. Of all 15 poplar clones compared in this study, the 72-16 clone of P. alba × glandulosa showed the best absorption capacity.

This study was conducted to estimate the capability of Populus alba × glandulosa and Betula schmidtii for the uptake of Pb from the lead-contaminated soil and their tolerance to lead. Rooted cuttings in the former species and germinated seedlings in the latter species were planted in pots and irrigated with Pb-containing water for 60 days. In both tree species, growth inhibition was observed in 800, and 1,500ppm of Pb(NO₃)₂. Most Pb was accumulated in plant roots and only a small portion was transported to the shoots. The translocation rates of Pb for B. schmidtii and P. alba × glandulosa were 1.6-2.6% and 1.2-1.6%, respectively. The maximum Pb content accumulated in shoots was 468.0㎎/㎏ d.w. in P. albs × glandulosa, and 602.0㎎/㎏ d.w. in B. schmidtii. Although tolerance to lead was generally higher in B. schmidtiithan P. alba × glandulosa, the highest tolerance to lead was observed in P. alba × glandulosa clone, 72-16. Finally, we discussed the applicability of P. alba × glandulosa and B. schmidtii for phytoextraction based on their Pb uptake ability, high biomass production, and easiness in large-scale cultivati

여진기(Jin-Kie Yeo),박정현(Jung-Hyun Park),구영본(Yeong-Bon Koo),김현철(Hyun-Chul Kim),신한나(Hanna Shin) 한국토양비료학회 2010 한국토양비료학회지 Vol.43 No.2

본 연구는 간척지에 자생하는 버드나무 (Salix koreensis Anderson)를 대상으로 염분에 대한 내성의 범위를 조사하기 위해 수행되었다. 간척지에서 선발된 버드나무6개체의 가지를 잘라 온실에서 삽목하여 2개월이 경과한 다음부터 NaCl 0.1%, 0.5%, 1.0% 용액과 지하수를 1개월간 관수하면서 재배하였다. 0.1% 및 지하수 처리구에서 전체 묘목의 생존율은 100%인 반면 0.5% 및 1.0% 처리구에서는 각각 73.2% 및 58.8%로 감소하였다. 0.1%와 지하수 처리구간의 묘고와 근원경 생장은 차이를 보이지 않았고 엽수는 실험기간동안 꾸준히 증가하는 경향을 보였다. 반면 0.5% 및 1.0% 처리구에서 묘고 생장은 지하수 처리구에 비해 각각 43.8% 및 88.9% 감소하였다. 0.5% 및 1.0% 처리구 묘목의 잎은 스트레스로 갈변하고 조기 낙엽되었다. 본 연구에 사용된 버드나무는 온실에서의 NaCl 처리결과 해안간척지에서 자생하는 개체임에도 불구하고 일반 임지에서 자생하는 버드나무보다 염분에 대한 내성 능력이 크지는 않은 것으로 추정된다. This study was conducted to investigate the potentials for the forest restoration on reclaimed land by using willow trees (Salix koreensis Anderson) selected from a coastal reclaimed land made in inside of the Sihwa tide embankment. We first collected six individual willow trees that were the only tree species grown in the reclaimed land. Total 7 clones from cuttings of the collected trees and the control were grown in a greenhouse for two months prior to applying the different concentrations of NaCl solutions (0.0%, 0.1%, 0.5%, and 1.0%). One month after the NaCl application, the survival rates of clones from both the collected trees, and the control were significantly decreased in a NaCl dose-dependent manner. However, there was no significant difference between the collected trees and the control in terms of survival rate, hight and diameter of cuttings, and the numbers of leaves in greenhouse condition. In conclusion, the willow trees collected from the coastal reclaimed land showed no tolerance against NaCl compared to the control grown in ordinary soil, suggesting that further study is required to determine what the most important factor is to select salt tolerant tree species.

최완용(Wan Yong Choi),여진기(Jin Kie Yeo),서강욱(Gang Uk Suh),김종한(Jong Han Kim) 한국육종학회 1994 한국육종학회지 Vol.26 No.4

As a first step in the study of genetics of Pinus thunbergii Parl., the inheritance and the linkage of the detected polymorphisms were elucidated. Megagametophyte tissues of individual seeds from a single clone were analysed by starch gel electrophoresis. Seven enzyme systems studied comprised a minimum of 17 isozyme loci. Among them, 11 were polymophic. Segregation of isozymes in megagametophytes of heterozygous maternal clones indicated no significant departure from the expected 1 : 1 ratio in each locus. Significant linkage, as attested by the 95% confidence interval, was recognized in six pairwise combinations. The pairs of the gene loci ME-B/LAP-A and ADH-B/MNR-C were closely linked with estimated mean recombination values of 0.153 and 0.175, respectively. The remaining tested pairs (ADH-B/ LAP-B, ME-B/MDH-C, MNR-B/MDH-C, and MNR-A/MNR-B) appeared to be weakly linked. The gene loci MNR-C, ADH-B, and LAP-B could be linearly arranged in one linkage group, while the loci LAP-A, ME-B, MDH-C, MNR-A, and MNR-B seemed to belong to the other linkage group. Considerable variation with respect to the estimated recombination frequencies was observed for the same pair of loci among some clones. A comparsion with other conifer species showed that the gene orders and distances were relatively well conserved among conifer species.

2012년 이후 해양투기가 전면 금지됨에 따라 가축분뇨 자원화 및 육상처리에 대한 대책으로 최근 산림지 및 조림지에 축산분뇨 액비를 처리하자는 대안이 대두되고 있다. 가축분뇨로부터 생산된 액비는 화학비료를 대신하여 자연순환농업에 효과적으로 사용될 수 있으며, 가축분뇨를 재활용할 수 있는 장점이 있다. 하지만, 액비는 시용량, 시용시기 등에 따라 환경, 특히 수질에 미치는 영향이 있을 것으로 판단된다. 따라서, 저농도액비 시용이 토양수 및 토양환경에 미치는 영향에 대한 모니터링과 분석이 필요하다. 본 연구는 경기도 수원시 호매실동에 위치한 포플러 재배지인 유휴지에서 저농도액비 시용이 토양수에 미치는 영향을 살펴보기 위하여 매주 토양수를 40 cm와 80 cm 깊이에서 액비처리구 3개소, 무처리구 2개소에서 모니터링을 실시하였으며, 이를 질산성질소와 총인 2개 항목에 대하여 분석하였다. 유휴지는 경사가 없고 54 EL.m의 고도이며, 배수가 약간 불량한 미사질 내지 식질 토양으로 조성되어 있다. 저농도액비 시용에 따른 토양수 수질 분석 결과, TN의 경우 액비처리구에서 무처리구보다 높게 나타났지만, 80 cm 토층에 대해서는 거의 차이가 없었으며, 7월 이후에는 작아지는 경향이 나타났다. 질산성질소 역시 액비처리구에서 무처리구보다 높았으나, 7월 이후 역시 작아지는 경향이 나타났다. 본 연구 결과를 바탕으로 추후 지속적인 모니터링을 통하여 저농도액비 시용에 따른 토양수 수질 분석 및 유휴지에서의 수질평가, 모형 구축의 기초자료로 활용될 수 있을 것으로 판단된다.

This study was conducted to estimate aboveground biomass and nitrogen storage potential of tree species-eight clones of a poplar and hybrids, one clone of Salix alba L., dawn redwood (Metasequoia glyptostroboides Hu and W.C. Cheng), yellow poplar (Liriodendron tulipifera L.), Okamoto maple (Acer okamotoanum Nakai), and pin oak (Quercus palustris Munchh.)- after treating with liquid pig manure. Stems showed the highest percentage of aboveground biomass, and followed by branches and leaves. Nitrogen content in aboveground biomass components was the highest in leaves, and followed by branches and stems. Average aboveground biomass production was higher in the clones and species treated with manure than those of not treated, 30 ton/ha and 16 ton/ha, respectively. In the manure-treated site, clone ``Dorskamp`` of Populus deltoides×Populus nigra showed the highest aboveground biomass (48.3 ton/ha). Average nitrogen storage potential was superior in the clones and species treated with manure than those of not treated, 159 kg/ha and 90 kg/ha, respectively. Clone ``Dorskamp`` also showed the greatest nitrogen storage potential (286.5 kg/ha) among tested tree species. Therefore, ``Dorskamp`` is the most suitable clone for treating liquid pig manure, but additional studies are needed to determine any damages or tolerance from the treatment.

SCB액비가 속성수의 생장 및 biomass 생산에 미치는 영향

김현철(Hyun-Chul Kim),여진기(Jin-Kie Yeo),구영본(Yeong-Bon Koo),신한나(Hanna Shin),최진용(Jin-Young Choi),이헌호(Heon-Ho Lee) 한국토양비료학회 2011 한국토양비료학회지 Vol.44 No.2

SCB액비, 저장액비, 화학비료, 지하수 및 무처리에 따른 포플러 및 버드나무 클론, 백합나무의 생존율은 전체 평균 94.4%로 나타나 양호하였으며, 잎과 줄기의 비율은 각각 63.5%, 36.5%로 매년수확구의 식재당년 지상부 biomass는 잎의 비율이 높았다. 처리구별 줄기발생 수는 SCB액비, 저장액비, 화학비료, 지하수 및 무처리구가 평균 4.2, 4.6, 4.5, 4.7, 4.9개로 크게 차이가 나타나지 않았으며 버드나무 클론들의 줄기 수가 포플러 클론 및 백합나무 보다 많았다. 줄기직경과 지상부 biomass에 대하여 개체당 유도된 회귀모델을 통해 추정된 biomass 생산량은 화학비료>저장액비>지하수>SCB액비>무처리구 순으로 나타났다. 수종 및 클론별 지상부 biomass 생산량은 모든 처리구에서 현사시 클론들이 우수하게 나타났으며, SCB액비 처리에 따른 잎과 줄기의 질소함량을 분석한 결과 무처리구 보다 질소함량이 높게 나타나 SCB액비에 함유된 질소를 체내에 흡수하는 것으로 판단된다. 따라서, SCB액비를 biomass 매년수확구에 처리한 결과 화학비료, 저장액비, 지하수 처리구보다 생산량이 적게 나타났지만 무처리구 보다는 생산량이 증가하여 향후 처리방법이나 적정 처리량 등을 구명하여 적용한다면 화학비료와 비슷한 효과를 얻을 수 있고 가축분뇨 처리비용도 절감할 수 있을 것으로 판단된다. 그러나 본 연구는 biomass 매년수확구의 식재당년의 결과이며, 식재한 묘목의 수령이 증가하고 입지환경에 적응되면 바이오매스 생산량도 대폭 증가할 것이므로 이와 같은 연구가 반복적으로 수행되어야 보다 확실한 결과를 얻을 수 있을 것으로 생각된다. Fifteen clones of poplars, 2 clones of willows, and yellow poplar were used to evaluate the effects of 5 treatments such as SCBLF (slurry composting and biofiltration liquid fertilizer), general slurry liquid fertilizer, chemical fertilizer, groundwater, and control (no treatment) on vitality, growth performance, and biomass production. Five cuttings for each tree species were planted in 3 replications. After planting cuttings, a coppice was induced by cutting off stems at 10cm above the ground. Data were collected for first growing season and trees were harvested at the end of October. Maximum mortality rate i.e. 96% was recorded in the cuttings treated with groundwater and minimum 92% with control (no treatment). In all tree species, sprouting of stump was not differ significantly among the treatments. Total nitrogen concentrations of leaves and stump sprouts were higher in the treatment of SCBLF than the control, 26.6% and 22.9%, respectively. Biomass production was highest in the stumps treated with chemical fertilizer, 1.98 Mg ha<SUP>-1</SUP> year<SUP>-1</SUP>, and lowest in control (1.34 Mg ha<SUP>-1</SUP> year<SUP>-1</SUP>).
