The experiment was conducted to test the effects of ectomycorrhizal inoculation and soil moisture regime on growth and nutrient uptake of Pinus rigida seedlings. Two-year-old seedlings inoculated with either Pisolithus tinctorius or Thelephora terrestris were used for this experiment. There were two moisture treatments and four phosphate treatment levels with three replications. Height and root collar diameter growth and dry weight increase were measured and nitrogen, phosphorous, and potassium in the tissue were analyzed three months after the initiation of phosphate and moisture regime treatment. Results are as follows; 1) Height growth of seedlings was not affected in all treatments. (mycorrhizae, fertility, moisture). 2) High moisture regime increased root collar diameter growth 2.7 .times as large as low moisture regime. 3) In low moisture regime, net production increased 26% in seedlings inoculated with Pisolithus tinctorius and increased 72% control seedlings. 4) In high moisture regime, net production of inoculated seedlings with Pisolithus tinctorius increased four times as much as that of control seedlings but increased P₂O_5 in fertility level did not affect net production. 5) In uptake of nitrogen, phosphate, and potassium, Pisolithus tinctorius - inoculated seedlings increased uptake by 1.9, 1.8, and 1.5 times, respectively, as much as control seedlings. 6) Increase in P₂O_5 fertility level enhanced the uptake of P₂O_5 in Pisolithus tinctorius - inoculated seedlings, but not affected the uptake of P₂O_5 in control seedlings. 7) Increase in P₂O_5 fertility levels enhanced the uptake of K₂O in Pisolirhus rinctorius - inoculated seedlings.

This study was conducted to determine the toxic effects of air pollutants on landscaping trees, Pinus densiflora, Pinus koraierasis, Ginkgo biloba, Liriodeytdron tulipifera, Platanus occidentalis and their resistance to the pollutant toxicity in urban and industrial regions of Seoul and Taejon, Korea. Total sulfur content and superoxide dismutase activity were analysed in tree foliage of Pinus densiflora, Pinzes koraiensis, Ginkgo biloba, Liriodendron tulipifera, Platanus occidentalis. In addition, SOD activity was analyzed in the foliage of tree seedlings, i.e. Pinus densijlora, Pinus koraiensis, Ginkgo biloba, Liriodendron tulipifera, with the lurnigation of SO₂ in gas chamber 4 hours a day for six days. In all species total sulfur content and SOD activity had a positive correlation. Air pollutants accumulated in tree tissues were supposed to enhance the enzyme activity like SOD providing with the resistance mechanisms. Trees under the air pollution stress increased enzyme activity to develop internal self-resistance against pollutants, but after a critical point enzyme-activity decreased gradually and resulting in injury after all, Deciduous trees had greater filtration capacity than conifers and coniferous trees showed greater resistance against air pollutants than deciduous species. Foliage SOD activity was higher in polluted area than in unpolluted area for most species. Coniferous species and mature trees had higher SOD activity than deciduous seedlings. Especially Pinus koraiensis, Ginkgo biloba and Plcatanus occidentalis had higher SOD activity than other species. The tree species with the high SOD activity showed strong resistance against air pollutants. In 2nd-year needles of Pinus densiflora seedlings and current and 2nd-year needles of Pinus koraiensis seedlings containing high native SOD activity, SOD activity increased with the increase of SO₂ level. But in seedlings containing low native SOD activity, SOD activity increased at 0.5ppm SO₂ level while it decreased at 1.5 and 2.5ppm SO₂. Changes of SOD activity was different between species and in most species SOD seemed to participate in resistance mechanism.

This study was conducted to determine the toxic effects of air pollutants on landscaping tress. Pinrrs densiflora, Pinus koraiensis. Ginkgo biloba. Liriodendron tulipifera, Platanus occidentalis and their resistance to the pollutant toxicity in urban and industrial regions of Seoul and Taejon. Korea. Total sulfur contents and enzyme activities such as superoxide dismutase and peroxidase were analyzed in tree foliage of Pinus densiflora, Pinus koraiensis. Ginkgo biloba. Liriodendron tulipifera. Platanus occidentalis. In addition. POD activity was analyzed in the foliage on tree seedlings, i.e. Pinus densiflora Pinus koraiensis. Ginkgo biloba, L irioderzdron tulipifera, with the fumigation of SO₂ in gas chamber 4 hours a day for six days. In Ginkgo biloba total sulfur content and POD activity had a negative correlation while other species had a positive relationship in total sulfur content and enzyme activity. Air pollutants accumulated in tree tissues were supposed to enhance the enzyme activity like POD providing the resistance mechanisms. Especially Pinus koraiensis and Platanus occidentalis had higher POD activity than other species. The increase of temporary POD activity against environmental stress appeared in sensitive trees and prolonged increase of POD activity played an important role in resistance mechanism. SOD and POD activities in all species had a positive correlation except Ginkgo biloba. Changes of SOD and POD activities were different between species and in most species SOD as well as POD seemed to participate in resistance mechanism.

This study was conducted to investigate sensitivity of tree seedlings to SO₂. Visible injury symptoms and changes of ethylene production were investigated in tree seedlings with the fumigation of SO₂ in gas chamber 4 hours a day for six days. The symptoms of visible injury did not appear below 0.5ppm level of SO₂ exposure but a change of visible injury with the passage of time appeared at 1.5 and 2.5ppm in all seedlings. With the higher the concentration and; or the longer exposure of SO₂ the visible injury symptoms on leaves increased in all seedlings. The sensitivity of seedlings to SO₂ was the highest in Liriodendron tulipifera followed by Pinus strobus, Ginkgo biloba, Pinus densiflora and Pinus koraiensis. The amount of ethylene production was more at 1.5 and 2.5ppm of SO₂ exposure than at 0.5ppm and the peak time of it came faster at higher levels. The amount of ethylene production was significantly different among tree seedlings. It showed a higher at production of ethylene in Liriodendron tulipifera compared to Ginkgo biloba and the ethylene production of Pinus trees to SO₂ were the highest in Pinus strobus followed by Pinus deyasiflora and Pinus konziensis. In needle of Pinus strobus the ethylene production increased with the increasing rate of visible injury until the injury rate of 40-50% and than decreased with the increasing rate of visible injury since the rate of 50%.

This study was conducted to investigate sensitivity of woody plants growing in urban and industrial regions of Seoul and Taejon, Korea. Malondialdehyde(MDA) contents were analyzed in tree foliage of Pinus densiflora, Pinus koraiensis, Ginkgo biloba, Liriodendron tulipifera and Platanus occidentalis. In addition, MDA contents were analyzed in the foliage of tree seedlings, i.e. Pinus densiflora. Pinus koraiensis, Ginkgo biloba and Liriodendron tulipifera, with the fumigation of SO₂ in gas chamber 4 hours a day for six days. MDA contents of leaves in Ginkgo biloba, Platanus occidentalis and Liriodendron tulipifera in polluted regions were higher than those in unpolluted region and among them Liriodendron tulipifera had the highest. MDA contents of .Pinus densiflora and Pinus koraiensis increased with the increase of needle age. MDA contents of Liriodendron tulipifera seedlings were increased with the higher concentrations of SO₂ but MDA contents in other seedlings showed no changes with SO₂ treatment concentrations. MDA contents in all species were increased with the passage of exposure day. Especially. Liriodendron tulipifera had higher MDA content than other species. In Liriodendron tulipifera the MDA production increased with the passage of exposure day until the fourth day after that decreased.

造景樹木의 大氣汚染物質에 대한 防禦機能 : SOD 活性을 중심으로 Superoxide dismutase Activity

金明姬,李壽煜 中部大學校 農業開發硏究所 1993 農業開發硏究論文集 Vol.2 No.-

造景樹木들의 大氣汚染物質들에 대한 感受性 및 抵抗性을 규명하기 위해서 野外調査와 室內實驗을 통하여 葉內 硫黃含量과 superoxide dismutase (SOD) 含量을 測定 分析하였다. 全 樹種에서 葉內 硫黃含量과 SOD 活性間에 正의 相關을 나타내었다. 植物體가 汚染物質에 대하여 自體防禦를 위하여 初期에는 酵素活性을 增大시키지만, 植物體의 收容限界를 넘을 때는 오히려 酵素의 失活과 함께 植物體가 被害를 받았다. 闊葉樹는 大氣汚染物質의 淨化能力이 큰 반면 針葉樹는 汚染物質에 대한 防禦能力이 크게 나타났다. 葉內 SOD 活性은 非汚染 地域과 汚染地域間에 差異가 뚜렷하였는데, SOD 活性은 闊葉樹에 비하여 針葉樹에서 높게 나타났으며, 소나무보다는 잣나무에서 活性이 높았으며, 튜립나무는 은행나무와 양버즘나무보다 낮은 것으로 나타나 SOD 活性이 높은것이 大氣汚染物質에 대한 耐性이 强함을 알 수 있다.
