몇 생리적 특성을 이용한 제일대잡종 poplar , Populus alba × Populus glandulosa F1 의 우량 clone 선발에 관한 연구
김갑태,이돈구 한국임학회 1983 한국산림과학회지 Vol.59 No.1
第一代 雜種 poplar, Populus alba × P. glandulosa F₁의 優良 clone을 選拔하기 위하여, 서울大學校 農科大學 苗圃場에서 密植栽培한 1, 2年生 各各 13, 15 clone을 對象으로 生長과 이에 關聯된 몇 生理的 特性을 調査 比較하였다. 個體當 乾重量, 個體當 葉面積, 單位葉面積當 葉綠素 含量에 있어서 2年生 clone間에는 高度의 有意性이 認定되었으나, 1年生에 있어서는 有意差가 認定되지 않았다. 個體當 乾重量과 個體當 葉面積의 相關係數는 r=0.865, 그리고 個體當 葉綠素含量과의 相關係數는 r=0.888로 高度의 相關이 認定되었으며, 個體當 光合性 能力과의 相關係數는 r=0.745로 比較的 높은 相關이 認定되었다. 1年生 clone의 葉順別 葉單位面積常 光合成能力과 葉綠素含量은 葉順이 增加함에 따라 增加하여 28번째, 33번째 葉에서 各各 最大値를 보였으며, 그후 아래로 내려올수록 점차 減少하는 傾向을 보였다. clone 68-1-54, 66-26-55, 65-22-11 等은 個體當 葉面積, 葉綠素含量과 光合成 能力으로 보아 다른 clone들보다 良好한 生長能力을 보였다. 第一代 雜種 poplar, Populus alba × P. glandulosa F₁의 生長量은 個體當 葉面積이나 個體當 葉綠素含量으로 推定할 수 있었다. 이러한 事實로 보아 個體當 葉面積이나 個體當 葉綠素含量의 測定値는 本 雜種 poplar clone의 成長을 推定하는 하나의 基準으로 使用될 수 있다.
亞黃酸이 은행나무(Ginkgo biloba)와 현사시 (Populus alba×Populus glandulosa F₁)의 葉組織에 미치는 影響
金甲泰 尙志大學校 1986 論文集 Vol.7 No.-
This study was carried out to understand the mechanism of plant injury with SO₂and compare Ginkgo biloba with Populus alba×Pupulus glandulosa F₁. Leat disks, 6mm diameter, cut from the leaves of two species, were incubated on the testing medium and placed on laboratory under tungsten lamp(1500 Lux) for 20 hours, to investigate the discoloration, chlorophyll content, and acidity of testing medium. Testing medium was diluted sulfurous acid solution with deionized water for various stoichiometric SO₂concentration, 0, 62.5, 125, and 250 ppm. The results obtained are as follows; 1) Leaf disks were turned to reddish brown color for both species, Discoloration of the leaf disks tended to be more serious with higher concentration of the medium, and the area of discolored leaf disks did more wide with higher concentration. 2) Total chlorophyll content of the leaf disk was obviously decreased according to the increase SO₂concentration of testing medium. Significant difference in decrease rate of total chlorophyll content of Populus with increasing SO₂concentration is greater than that of Ginkgo. 3) Decrease of total chlorophyll content was mainly due to the decrease of chlorophyll a content for both species. 4) The acidity of testing medium incubated Populus changed lower than that of testing medium incubated Ginkgo, and it means that more cell leakage was occured in Populus leaf disks during incubation. 5) The acidity of deionized water medium incubated Ginkgo was increased, but that incubated Populus was decreased, it means that the acidity and buffer capacity of the leaf tissue differ from one species and another. 6) From these results, I understand that the resistance to SO₂is quite different between tree species, and more detailed research is required.
지리산 천왕봉 - 덕평봉 지역의 삼림군집구조에 관한 연구 : 구상나무림 Abies koreana Forest
김갑태,추갑철,엄태원 한국임학회 1997 한국산림과학회지 Vol.86 No.2
To investigate the structure and the conservation strategy of Korean native species, Abies koreana forest at Cheonwangbong-Deokpyungbong area in Chirisan National Park, 48 plots(10 × 10m) were set up with random sampling method. Three groups - Abies koreana community, Abies koreana-Quercus mongolica community, Picea jezoensis-Betula ermanii community - were classified by cluster analysis. High positive correlations were shown between Picea jezoensis and Sorbus commixta : Quercus mongodica and Fraxinus sieboldiana, Symplocos chinensis : Euonymus macroptera and Vaccinium koreanum, and high negative correlations were shown between Quereus mongolica and Sorbus commixta. Species diversity(H') of investigated area was calculated 0.7208-1.2074. Vigor of Abies koreana was depressed, 12.24 of total number of Abies koreana investigated were dead. DBH of dead individuals ranged mainly 10×30㎝.

This study was conducted to maintain the productivity of forest production and byproducts production of natural forest. Distribution of wild edible herb species and correlations between wild edible herb species and forest-type, and site factors were surveyed on national forest in Changjeon-ni, Pyungchang-gun, Kang-won-do. Ligularia fischeri was distributed mainly on cutting sites or meadow or Quercus mongolica forest, Pimpinella brachycarpa did on broadleaved mixed forest, and Synurus deltoides did cutting sites or meadow. On conifer plantations major wild edible herb species were not distributed. Pimpinella brachycarpa and Ligularia fischera were distributed mainly on the site of wet soil-moisture condition, Codonopsis lanceolata, Saussurea grandifolia and Synurus deltoides were distributed randomly. The distribution of Ligularia fischeri and Pimpinella brachycarpa were significantly different between slope directions, but those of Codonopsis lanceolata, Saussurea grandifolia and Synurus deltoides were not significant. Ligularia fischeri and Pimpinella brachycarpa were distributed more frequently in north directed slope than the other. Highly positive correlations were proved Ligularia fischeri and Pimpinella brachycarpa, Aconitum jaluense and Veratrum patulum; Pimpinella brachycarpa and Smilacina japonica, Aconitum jaluense and Veratrum patulum.
임분의 광환경이 활엽수 3수종의 광합성율 및 엽록소 함양에 미치는 영향
김갑태 한국환경생태학회 2005 한국환경생태학회지 Vol.19 No.2
이 연구는 큰 나무 아래 어린 나무를 심어 (수하식재) 새로운 숲을 가꾸는 방법 (임분갱신법)을 찾고자 낙엽송 간벌지에 음나무, 물푸레나무 및 층층나무 묘목을 1998년 봄에 수하식 재 한 것과 이웃에 위치 한 동일한 묘령의 임간포지에서 생육하는 개체들과의 엽록소항량과 광합성율을 2000년 7월에 측정·비교하였다. 이는 식물종에 따른 광량에 대한 적응력 차이 (내음성)를 생리학적으로 확인하고자 시도하였다. 낮은 광도에 적응하기 위하여 음나무 잎은 다른 수종들에 비하여 보다 많은 엽록소함량과 광합성능을 증가시 키는 반응을 보였다고 판단된다. 이러한 결과로 보아 내음성은 음나무, 물푸레나무, 층층나무의 순으로 낮아지는 것이라 판단된다. To seek for proper regeneration methods with under-planting, Photosynthetic rate and chlorophyll contents of three broad-leaved species seedlings, Kalopanax pictum, Fraxinus rhynchophylla and Cornus controversa, were measured and compared between growing sites, below the canopy of Larix kaemferi and open land in the forest. Nursery stocks was planted in open nurs- ery in the forest in late April, 1997, and under-planting below the canopy of Larix kaemferi was conducted in late April, 1998. This experiment examined the relationships between shade-tolerance and physiological response to different light environment by tree species. To adapt the shade environment, leaves of Kalopanax pictum might be increased the more chlorophyll con- tents and photosynthetic ability than other species. From these results, shade-tolerance of the tree might be ordered Kalopanax pictum, Fraxinus rhynchophylla, and Cornus controversa.
