The purpose of this study was to examine potential effects of shading and fertilizing treatment - two basic applicable factors in production of 1-year-old container seedling - on growth and seedling quality of Quercus myrsinaefolia, one of evergreen tree species in warm temperate zone of Korean. Every experimental process was conducted in a facility that consisted of compartments under the lighting control with full sunlight and shading (35%, 55% and 75% of full sunlight). Based on fertilizing treatment, this study made an experiment in 4 groups of container seedling: control (non-treated seedlings) and 1000, 2000, 3000 ppm group (3 groups with different concentrations of water-soluble fertilizer (N:P:K=19:19:19, v/v). Seedlings under 55% shading with 2000 ppm concentration showed the highest height (totaling 21.1 cm), and under 35% shading with 2000 ppm concentration showed the highest root collar diameter growth (totaling 3.96 mm) among others. All three fertilizing groups except control showed H/D ratio ranging from 4.27 to 5.26 regardless of fertilizer concentration under 35% and 55% shading where container seedlings showed a tendency toward excellent growth of height and root collar diameter. Overall, 2000 ppm group under 55% shading showed highest dry mass production of leaves (1,292 g) among others, while 2000 ppm group under 35% shading showed highest dry mass production of shoots and roots (0.592 g and 0.998 g, respectively) among others. Also, it was found that 2000 ppm group under 35% shading showed the highest dry mass production of whole seedling, which was followed by 2000 ppm group under 55% shading and 3000 ppm group under 35% shading, respectively. According to analysis on LWR of Quercus myrsinaefolia depending on shading and fertilizing treatment, it was found that 3000 ppm group under 75% shading showed highest LWR level among others, whereas every fertilized group showed lower RWR level than control without fertilizing regardless of shading levels. In general, all fertilized groups under 55% shading had relatively high quality index (QI), and 2000 ppm group under 35% shading had highest QI among others. Based on the findings of this study, it is concluded that shading level ranging from 35 to 55% and fertilizing concentration of 2,000 ppm are suitable for producing 1-year-old container seedlings of Quercus myrsinaefolia with excellent growth and high quality index.

본 연구는 피음처리에 따른 1년생 가시나무 용기묘의 생장과 생리적 반응을 탐구하고자 수행되었는데, 피음처리는 전광 및 전광의 35%, 55%, 75%의 수준으로 실시하였다. 가시나무의 간장과 근원경생장은 35%와 55% 피음처리에서 높은 것으로 조사되었으며, 피음처리와 상관없이 근원경생장이 간장생장 보다 4주 정도 더 길게 지속되었다. 피음처리 후 가장 높은 H/D율은 4.31을 기록한 35% 피음이었으며 가장 낮은 값은 3.63을 기록한 75% 피음이었다. 또한 피음처리 후 가장 높은 건물생산량은 55% 피음, 그 다음으로는 35% 피음이었는데, 부위별로도 이 두 피음수준에서 가장 높은 것으로 조사되었다. T/R율은 75% 피음에서 1.76으로 가장 낮게 나타났고 55%에서 2.41로 가장 높게 나타났으며 35%에서는 2.38로 조사되었다. Leaf dry weight ratio(LWR)의 경우, 피음처리 후 가장 높은 값은 55% 피음의 0.53, 다음은 35%의 0.52이었으며, root dry weight ratio(RWR)은 피음수준이 가장 높은 75%에서 0.36으로 가장 높은 것으로 조사되었다. 피음이 강해질수록 엽록소 a 함량과 총 엽록소(a + b) 함량은 높아지는 경향을 보였지만 엽록소 b의 경우에는 피음처리에 따른 차이가 나타나지 않았다. 그리고 광합성률과 증산율은 전광에 비해 피음이 높을수록 증가하였으나, 가장 높은 피음인 75%보다는 35% 및 55% 피음에서 더 높았다. 본 실험에서 피음처리에 따른 광 조건이 다른 환경에서 생육한 묘목들이 보인 생장과 광합성 반응 결과는 적정 생육광도를 설정하는 데 유용하게 사용될 수 있으며, 또한 내음성 정도를 추정하는 자료로도 활용될 수 있을 것으로 사료된다. This study was carried out to investigate the growth and physiological responses to shading treatment of 1-year-old containerized seedling of Quercus myrsinaefolia. Experimental process was conducted in a facility that consisted of compartments under the lighting control with full sunlight and shading (35%, 55% and 75% of full sunlight). Height and root collar diameter growth were high in the seedlings under both 35% and 55% shading. Regardless of shading level, root collar diameter growth lasted for more than 4 weeks compared to height growth. Highest H/D ratio was observed in the seedlings under 35% shading as 4.31, and the lowest ratio was 3.63 under 75% shading. It was found that seedlings under 55% shading showed highest dry mass production, which was followed in seedlings under 35% shading. In case of leaf dry weight ratio (LWR) after shading treatment, the highest value was 0.53 under 55% shading, and followed in seedlings under 35% shading as 0.52. But root dry weight ratio (RWR) was highest as 0.36 under 75% shading (highest level of shading). In terms of shading treatment, it was found that the higher level of shading had a tendency toward the higher content of chlorophyll a and the higher total chlorophyll content in the leaves of Quercus myrsinaefolia, but there was no significant difference in the content of chlorophyll b depending on the level of shading. It was found that high photosynthesis and transpiration rate were more correlated with high level of shading than full sunlight, but the rates of seedlings had a tendency to be higher under 35% and 55% shading than under 75% shading. The results on growth and physiological responses to different shading levels of 1-year-old containerized seedlings of Quercus myrsinaefolia could be useful in setting up the optimum light intensity for growth, and in estimating the shade tolerance of the species.

본 연구는 대체에너지, 생태복원 및 밀원식물용 등으로 이용되어 묘목 수요가 증가되고 있는 쉬나무의 우량한 용기묘 생산을 위한 적정 차광수준을 구명하고자 실시하였다. 공시용기는 임업시설양묘용 플라스틱 용기(350ml/구)를 사용하였다. 차광수준은 전광과 전광의 35%, 55%, 75%로 처리하였다. 실험결과, 간장과 근원경 생장은 전광에서 현저히 높은 값을 보였으며, 차광수준이 강해질수록 낮은 생장값으로 조사되었다. 묘목의 뿌리형태특성을 측정한 결과 전광에서 뿌리 발달이 가장 왕성하게 조사되었다. 건물생산량도 전광에서 가장 높았고 전체적으로 간장 및 근원경 생장 결과와 유사한 경향으로 나타났다. 묘목의 품질을 나타내는 지수인 QI(Quality Index)도 차광실험의 경우 전광에서 0.98로 가장 높게 조사되었다. 묘목의 엽록소 함량은 상대적으로 차광수준이 가장 높은 75% 차광처리에서 가장 높은 엽록소 함량을 보였으며, 광합성속도 및 수분이용효율은 전광에서 각각 8.48μ molCO₂‧m<SUP>-2</SUP>s<SUP>-1</SUP>, 1.40μmolCO₂‧mmolm<SUP>-1</SUP>H₂O 가장 높은 것으로 조사되었다. 연구결과를 종합하면, 쉬나무 용기묘의 우량한 묘목생산을 위한 적정 차광수준은 전광(0%)으로 판단되며, 쉬나무 용기묘의 대량생산을 위한 기초자료로 활용될 것으로 기대된다. This study was conducted in order to closely examine about optimum shading for superior seedling production a container seedling of Tetradium daniellii, which is being increased the demand for a seedling due to being used for alternative energy, ecological restoration and honey plant. The experiment of investigating the optimum shading on T. daniellii was carried out by using plastic container types (350 ml/cavity) for the forestry facility cultivation. The shading level was treated with full sunlight and with 35%, 55%, 75% of the full sunlight. As a result of having surveyed height and root collar diameter growth of a containerized seedling in T. daniellii, a case of the shading experiment showed a noticeably high value was indicated in the full sunlight. It was surveyed that the stronger shading level leads to the lower growth value. Root development was most active in full sunlight. Dry matter production, it was investigated to be the highest in full sunlight. It was surveyed to be the similar tendency to the outcome of height and root collar diameter growth. QI, which is index of showing the quality of a seedling, stood at 0.98 in full sunlight, thereby having been investigated to be the highest. As for the chlorophyll content in a seedling, the highest chlorophyll content was indicated in the 75% shading treatment with the relatively highest shading level. The photosynthetic rate and the water use efficiency were surveyed to be the highest in full sunlight with 8.48 μmolCO₂‧m<SUP>-2</SUP>s<SUP>-1</SUP>, 1.40 μmolCO₂‧ mmolm<SUP>-1</SUP>H₂O, respectively. As a result of surveying the whole experiment, optimum shading level for superior seedling production a container seedling of T. daniellii is determined in full sunlight (0%). It is expected that this will be used as a basic data for mass production.

BACKGROUND: This study was carried out in order to closely examine the influence of fertilization upon growth in container of seedling in indeciduous Quercus species (Q. mysinaefolia, Q. acuta and Q. glauca). METHODS AND RESULTS: Fertilizer level was made by adjusting water soluble compound fertilizer (N:P:K=19: 19:19, v/v) to 1000, 2000, 3000 mg.L-1 level along with non-fertilizing plot. Fertilization increased height, root collar diameter growth, and dry weight in these three species of trees. The more increase in fertilizer level led to the more rise even in growth of these species. H/D ratio and T/R ratio also showed tendency of getting bigger in the more rise in fertilizer level. Photosynthetic rate was shown to get higher in the higher fertilizer level according to fertilization in all the three species. In the analysis of root morphological traits, the total root length was surveyed tobe longer in the more rise in fertilizer concentration. As even a case of root project area, surface area, and root volume is the similar tendency to characteristics in the total root length, a rise depending on fertilization was observed. CONCLUSION: In light of the results in this experiment, the fertilizer level is judged to be 2000 mg.L-1 level that is proper for production of 1-year-old container seedling in indeciduous Quercus species with excellent root development and high seedling quality index.

본 연구는 서울 용마산 소나무군락의 구과 및 종자의 발달특성을 파악하기 위하여 남서사면과 북동사면에 분포하고 있는 군락을 대상으로 2013년 3월 9일부터 10월 1일까지 수행되었다. 조사 초기부터 비슷한 생장을 보이던 두 조사지의 구과는 6월 3일 이후 남서사면 소나무의 구과 크기가 빠르게 생장하면서 구과의 길이와 폭에서 차이를 보였지만, 8월 9일경부터는 그 차이가 작아지기 시작하였다. 한편, 10월 1일 마지막조사에서는 남서사면 소나무의 구과 길이가 4.5mm, 북동사면은 4.2mm로 조사되어 서로 큰 차이는 나지 않았다. 종자발달의 경우, 처음에는 비슷한 생장을 보이다가 5월 28일부터 남서사면의 종자가 빠르게 생장하여 6월 24일에는 남서사면의 종자 길이는 4.5mm, 북동사면의 종자 길이는 2.7mm로 조사 기간 중 가장 큰 차이로 기록되었다. 하지만 이 기간 이후부터 남서사면의 종자 길이는 큰 변화가 없었던 반면 북동사면 종자는 지속적인 생장을 보여, 종자 길이생장이 거의 멈춘 시점인 9월 3일 조사에서 남서사면의 종자의 길이가4.8mm, 북동사면의 종자의 길이가 4.6mm로 차이가 크지 않았다. 한편 남서사면의 종자는 7월 1일경부터 종자표피의 색이 흰색에서 황색으로 변해 가면서 표피가 단단해지기 시작하였고 또 종자 날개가 형성되기 시작하였으나 북동사면의 경우는 이러한 현상이 7월 26일경부터 나타나기 시작하였다. 구과 성숙이 완료되는 9월 말부터 채집한 구과에서 분리되는 종자의 개수는 남서사면의 구과에서 38.4개, 북동사면에서 25.8개로 남서사면의 소나무의 종자 생산성이 좋은 것으로 조사되었다. To understand the characteristics of development of cone and seed of Pinus densiflora in Mt. Yongma, this study was performed from March 9th of 2013 to October 1st with the stands on south-west facing slope and north-east facing slope. At first, growth of cones of both stands seemed similar but there were difference in length and width of cones after June 3rd since the cone of south-west facing slope grew faster then, but the difference decreased from August 9th. Meanwhile in last investigation performed on October 1st, cone length of south-west facing slope was 4.5 mm and one of north-east facing slope was 4.2 mm showing little difference. At first seed development seemed similar but from May 28th seed of south-west facing slope grew faster. So on June 24th seed length of south-west facing slope was 4.5mm and north-east facing slope was 2.7 mm, showing biggest difference during the investigation. But after this time, there were no change in seed length of south-west facing slope while seed of north-east facing slope grew continuously, when it stopped growing seed length of south-west facing slope was 4.8mm and north-east facing slope was 4.6mm showing little difference. Meanwhile from July 1st, seed coat of south-west facing slope changed to yellow from white, seed coat firmed and seed wing started to develop, but in north-east facing slope these phenomenon started from July 26th. At the end of September when cones have reached full maturity, number of seed from cone was 38.4 in south-west facing slope and 25.8 in north-east facing slope, and the trees in south-west facing slope seemed to have better productivity.

본 연구는 우리나라 자생수종인 진달래(Rhododendron mucronulatum Turcz.)의 열매 및 종자의 특성을 조사하여 종자를 통한 대량번식 기술의 기초자료를 확보하고자 실시하였다. 진달래 열매는 강화군 고려산(435 m)에서 2013년 8월 26일, 9월 5일, 9월 12일, 10월 4일에 각각 채취하였다. 채취된 종자의 발아 온도 실험은 5, 10, 15, 20, 25, 30℃에서 실시하였다. 열매의 함수율은 2013년 9월 5일 채취 열매에서 54.5%로 가장 높았으며, 채취일자에 관계없이 열매의 종자개수는 91.3∼116.3개였다. 종자의 길이는 10월 4일 채취 종자에서 1947.4 ㎛, 폭은 9월 12일에서 727.3 ㎛로 가장 컸다. 발아율은 종자의 채취시기에 관계없이 25℃에서 높았으며, 9월 12일 채취한 종자에서 27.3%로 가장 높았다. 한편, 채취시기와 관계없이 5, 10 및 30℃에서는 전혀 발아가 되지 않았다. T₅₀과 평균발아일수는 온도가 높아질수록 짧아지는 경향을 보였으며, 발아균일도는 채취시기가 늦을수록 낮아지는 경향을 보였다. 발아속도는 25℃에서 가장 빠른 것으로 조사되었다. 본 실험의 결과를 종합해 볼 때 진달래 종자의 적정 채취시기는 9월 12일~10월 4일 경이며, 적정 발아 온도는 25℃인 것으로 판단된다. This study was carried out in order to secure basic data of seedling mass propagation technique of Rhododendron mucronulatum which is the native tree species of Korea by surveying the characteristics of its fruit and seed. The fruits were collected at Mt. Goryeo in Ganghwa-gun on different dates in 2013; August 26th, September 5th, September 12th, October 4th. The seed germination test was carried out at 5, 10, 15, 20, 25 and 30℃. Moisture content of the fruit was highest (54.5%) in the fruit collected on September 5th. Number of the seeds in a fruit was 91.3 to 116.3, regardless of the collection date. Seed length was highest (1947.4 ㎛) in the seeds collected on October 4th and seed width was highest (727.3 ㎛) in the seeds collected on September 12th. Germination rate of the seeds was highest at 25℃ regardless of the seed collection date, which showed the highest value(27.3%) in the seeds collected September 12th. Meanwhile, the seeds were not germinated not at all at 5, 10 and 30℃. T₅₀ and mean germination time of the seeds got shorter at the higher temperature. Germination uniformity got lower when the collection date got later. Germination speed of the seeds was fastest at 25℃. According to the results of this study, it seems that the appropriate time to collect fruit and seed is between September 12th and October 4th, and the appropriate temperature for the seed germination is 25℃.

본 연구는 대체에너지, 생태복원 및 밀원식물용 등으로 이용되어 묘목 수요가 증가되고 있는 쉬나무(Tetradium daniellii (Benn.) T. G. Hartley)의 우량한 용기묘 생산을 위한 적정 용기 규격(생육밀도, 용적 등)을 구명하고자 실시하였다. 적정 용기 구명 실험은 쉬나무를 임업시설양묘용 플라스틱 용기 5종(500 ml, 350 ml, 320 ml, 300 ml, 250 ml)을 사용하여 실시하였다. 실험결과, 간장과 근원경 생장은 SI 350 용기에서 현저히 높은 값을 보였으며, 대체적으로 용기 구 용적이 크고 생육밀도가 낮을수록 높은 생장을 나타냈다. 묘목의 뿌리형태특성을 측정한 결과 SI 350 용기에서 뿌리발달이 가장 왕성하게 조사되었다. 건물생산량도 SI 350에서 가장 높았고 전체적으로 간장 및 근원경 생장 결과와 유사한 경향으로 나타났다. 묘목의 품질을 나타내는 지수인 QI(Quality Index)도 SI 350 용기에서 0.97로 가장 높게 조사되었다. 연구결과를 종합하면, 쉬나무 용기묘의 우량한 묘목생산을 위한 적정 용기 종류는 SI 350 용기로 판단된다. There is an increasing demand for Tetradium daniellii seedlings due to their uses as alternative energy, for ecological restoration, and as a honey plant. This study was conducted to determine the optimum container for superior seedling production of T. daniellii. Experiments were performed using five plastic container types (500, 350, 320, 300, and 250 ml) for forestry facility cultivation. The height and root collar diameter growth of T. daniellii seedlings were significantly high in the 350-ml container. High growth appeared primarily in the container with a larger cavity volume and lower growing density. Root development was most active in full sunlight. The maximum dry matter production was observed in the 350-ml container, which was similar to the results of height and root collar diameter growth. QI, an index showing the quality of a seedling, was maximum at 0.97 in the 350-ml container. In conclusion, the 350-ml container is optimum for superior seedling production of T. daniellii.

This study was carried out in order to closely examine quality index by shading level of 2-year-old (1-1 seedling) container seedling of Daphniphyllum macropodum which is known as the species of having shade tolerance that is evergreen broad leaved tree in the warm temperate region. The shading treatment was regulated with the shading level of full sunlight, and 35%, 55%, 75%, 95% of full sunlight. As a result of surveying growth according to the shading level, both height and root collar diameter were surveyed to be the highest with 45.1 cm and 8.22 mm, respectively, under 75% of shading. The next was surveyed to be 43.2 cm & 8.05 mm and 42.5 cm & 7.98 mm, respectively, in order of 35% and 55% in shading. Leaf, shoot, root, and whole dry mass production were the highest under 75% of shading. The next was higher in leaf, stem, and whole dry mass production under 55% of shading. A root was higher under 35% of shading in the next. H/D ratio was the range of 5.29~5.35 under the 35~75% shading that showed the relatively high height and root collar diameter. T/R ratio was the lowest with 1.17 under 35% of shading. It was 0.41 under 95% of shading as for LWR, 0.24 under 75%-95% of shading as for SWR, and 0.46 under full sun and 35% shading as for RWR. QI was the highest with 3.74 under 75% of shading. As a result of surveying the whole experiment, it is concluded that the production of D. macropodum seedling is more effective under 75% shading

본 연구는 우리나라의 대표적인 조림수종인 소나무를 대상으로 조림지 식재 후 활착률을 높이기 위해 상대적으로 생육이 좋은 용기묘로 생산하고자 할 때, 관수처리수준에 따른 생장 반응 특성을 조사하고 이를 통하여 적정 관수 수준을 구명하고자 실시되었다. 104구 용기에서 생육된 소나무 용기묘는 대조구(무관수)를 포함하여 파종 후 15주부터 8주 동안 각각 1, 2, 3, 5, 7, 10, 15일 간격으로 관수되었다. 관수처리에 따른 소나무 용기묘의 간장과 근원경 생장, 건물생산량을 조사한 결과 가장 좋은 생장 반응은 관수처리 1일 간격에서 가장 높게 나타났다. 관수주기가 짧아질수록 소나무 용기묘의 생장이 좋아졌지만, 전체뿌리길이는 2일이나 1일 관수주기보다 3일에서 더 높게 나타났다. 묘목품질지수의 경우 1일 간격에서 가장 높고 관수주기가 길어질수록 낮아지는 경향을 보였다. 본 연구결과를 종합하면 1~2일 간격의 관수가 소나무 용기묘의 생육에 있어 적합한 것으로 판단된다. To identify the appropriate irrigation level for Pinus densiflora, a common reforestation species in Korea, we investigated their growth response characteristics according to different irrigation treatment levels for producing container seedlings with relatively high growth rate for higher survival rate when planted at the reforestation site. The container seedlings including control seedlings (no irrigation was applied) were grown in 104-cell trays were irrigated for 8 weeks from 15 weeks after seeding, at intervals of 1, 2, 3, 5, 7, 10, and 15 days. Analysis of the height growth, root collar diameter growth, and dry matter production of the container seedlings according to irrigation showed that the highest growth reaction was observed for the irrigation interval of 1 day. A shorter irrigation cycle resulted in better growth of the container seedlings, but overall, longer total root length were observed with an irrigation cycle of 3 days compared with cycles of 1 or 2 days. Quality index (QI) was the highest for the irrigation interval of 1 day, and tended to decrease with increase in the irrigation interval. Thus, it was determined that irrigation at intervals of 1-2 days was appropriate for growing Pinus densiflora container seedlings.
