To obtain the basic data for the conservation and cultivation of native herb species under the forest, the relations between distribution of native herb species and site factors, distribution of native herb species, and site factors were surveyed on natural forest at subalpine zone in Mt. Odae. Ainsliaea. acerifolia, Pseudostellaria palibiniana and Pimpinedla brachycarpa were distributed mainly on broadleaved mixed forest, Clematis fusca var. coreana, Carex saderosticta. Isodon excisus and Vicia unijuga did mainly on gab sites. The distribution of Ligularia fisheri. Aconitum pseudo-laeve var. erectum, Cacalia hastata and Artemisia stolonifera were significantly differed between slope directions. Artemisia stolonifera was distributed more frequently in south directed slope, and Ligularia fisheri, Aconitum pseudo-laeve var. erectum and Cacalia hastata were distributed more frequently in north and west directed slope than the other. The distribution of Aconitum pseudo-laeve var. erectum and Artemisia stolonifera were significantly differed between soil moisture conditions. Artemisia stolonifera was distributed mainly on the dry site, but Aconitum pseudo-laeve var. erectum did mainly on the dry site. Negative correlations between density of Clematis fusca var. coreana, Carex siderosticta. Isodon excises and Vicia unijuga and crown coverage was proved. Aconitum pseudo-laeve var. erectum, Pimpinella brachycarpa, Meehania urticifolia, Smilacina japonica and Pseudostellaria palibiniana were mainly distributed on wet and shady sites under forest canopy, but Pedicularis resupinata, Clematis fusca var, coreana and Artemisia stolonifera did on sunny sift forest edge or gab.

김갑태,Kim, Gab-Tae 한국환경생태학회 2014 한국환경생태학회지 Vol.28 No.4

우리나라에서 개미가 종자를 분산시키는 식물종과 그 종자의 특성을 밝히고자, 2012년 4월부터 2013년 10월까지 열매 수집, 전파체 특성, 관련된 개미종을 조사하였다. 개미가 종자를 퍼뜨리는 엘라이오솜을 종자에 부착한 8종의 식물을 추가로 확인하였다. 종자에 부착된 엘라이오솜의 형태는 종마다 형태나 크기가 매우 다양하였다. 전파체를 물어가는 개미종은 곰개미, 곰뿔개미, 누운털개미, 주름개미, 긴호리가슴개미, 고동털개미 등 6종이었으며, 일본왕개미나 몸집이 작은 사쿠라개미 등은 전파체를 물어가지 않았다. 이러한 결과는 여름철에 개화하는 식물종도 개미와 엘라이오솜을 매개로 하는 상리공생함을 확인하였다. 앞으로 개미가 종자를 퍼뜨리는 자생 식물종을 파악하기 위한 많은 연구가 필요하다. To search for native myrmecochorous plant species in Korea and their diaspore characteristics, collecting their fruits and diaspores, and the related ant species were studied from April 2012 to October 2013. Eight herb species growing in Korea are added to the myrmecochorous (seed attached elaiosome) plant list. Elaiosomes of eight herb species vary considerably in shape and size. Major ant species transporting the diaspore of myrmecochorous plants are Formica japonica, Lasius alienus, L. japonicus, Myrmica lobicornis, Temnothorax spinosior, Tetramorium tsushimae, but Camponotus japonicus and Nylanderia sakurae do not transport the diaspores. This study found out that mutualism between myrmecochorous summer-flowering plants and ants is carried out in Korea. Further research on the native myrmecochorous plants should be needed.

김갑태,Kim, Gab Tae 한국산림과학회 1989 한국산림과학회지 Vol.78 No.2

$SO_2$에 대한 내성수종(耐性樹種)을 선발(選拔)하기 위하여, 6수종(樹種)에 대하여 인공산성우(人工酸性雨)를 처리(處理)하면서 엽피해율(葉被害率), 엽록소함량(葉綠素含量) 및 생장(生長)을 조사(調査)하고, 산성연무(酸性煙霧)를 처리(處理)하면서 엽피해율(葉被害率)을 조사(調査) 비교(比較)하였다. 찔레는 처리산성우(處理酸性雨)의 pH값이 작아질수록 묘고생장(苗高生長)이 나빠졌으며 대조구에서 가장 좋게 나타났으나 가중나무는 pH 5.0 처리구(處理區)에서 묘고생장(苗高生長)이 가장 좋게 나타났다. 아까시나무, 일본목련 및 등나무는 pH 5.0 처리구(處理區)에서 지상부(地上部)와 지하부(地下部)의 생장(生長)이 모두 대조구(對照區)보다 좋게 나타나 상대적(相對的)으로 타수종(他樹種)에 비(比)해 산성우(酸性雨)에 대한 내성(耐性)이 강(强)할 것으로 기대(期待)된다. 처리산성우(處理酸性雨) 및 산성연무(酸性煙霧)의 pH 값이 작아질수록 모든 수종(樹種)에서 엽피해율(葉被害率)(피해엽면적(被害葉面積)과 피해엽율(被害葉率))이 증가(增加)하였다. 수종별(樹種別)로 처리간(處理間) 엽록소함량(葉綠素含量)의 변화(變化)는 조금씩 차이(差異)가 있으나, 찔레의 경우(境遇)는 측정시기(測定時期)에 관계(關係)없이 처리산성우(處理酸性雨)의 pH값이 작아질수록 총엽록소함량(總葉綠素含量)이 낮아지는 경향(傾向)이 있으며 일본목련의 경우(境遇)는 7월 측정(測定)에서는 처리산성우(處理酸性雨)의 pH 값이 작아질수록 총엽록소함량(總葉綠素含量)이 월등(越等)히 높았다가 산성우처리(酸性雨處理)가 계속(繼續)됨에 따라 감소(減少)하여 9월 측정(測定)에서는 처리산성우(處理酸性雨)의 pH 값이 작아질수록 총엽록소함량(總葉綠素含量)이 현저(顯著)히 낮아졌다. Seedlings of 6 tree species were treated with artificial acid rain and acid mist (pH 5.0, 4.0, 3.0) and ground water (pH 6.5), to select $SO_2$-resistant tree species. The growth variable, leaf injury rate and chlorophyll content were measured and compared among the various pH levels. Seedling height of Rosy multiflora decreased with deceasing pH levels of artificial acid rain and was tallest at control plot, but that of Ailanthus altissima was tallest at pH 5.0 plot. For the seedlings of Robinia pseudoacacia, Magnolia obovata and Wistaria floribunda, top and root dry weights per seedling at pH 5.0 plot were higher than those at control plot. Leaf injury rate(injured leaf area and injured leaf rate) increased with decreasing pH levels of artificial acid rain, the changes of leaf chlorophyll content was slightly different among tree species. Leaf chlorophyll content of Rosa multiflora, measured during the period July to September, decreased with decreasing pH levels of artificial acid rain. Leaf chlorophyll content of Magnolia obovata increased on July, but decreased severely on September, with decreasing pH levels, of artificial acid rain.

김갑태,이돈구,Kim, Gab Tae,Lee, Don Koo Korean Society of Forest Science 1983 한국산림과학회지 Vol.59 No.1

제일대(第一代) 잡종(雜種) 포플러 Poulus alba${\times}$Populus glandulosa $F_1$의 우량(優良) clone을 선발(選拔)하기 위해, 서울대학교(大學校) 농과대학(農科大學) 묘포장(苗圃場)에서 밀식재배(密植栽培)(20.000본(本)/ha)한 1,2년생(年生) 각각(各各) 13,15 clones을 대상(對象)으로 생장(生長)과 생장(生長)에 관련(關聯)된 몇 생리적(生理的) 특성(特性)을 조사(調査), 비교(比較)하였다. 개체당(個體當) 건중량(乾重量), 엽면적(葉面積), 단위엽면적당(單位葉面積當) 엽록소(葉綠素) 함량(含量)에 있어서 2년생(年生) clone들 간(間)에는 고도(高度)의 유의차(有意差)가 인정(認定)되었으나, 1년생(年生) clone들에 있어서는 유의차(有意差)가 인정(認定)되지 않았다. 개체당(個體當) 건중량(乾重量)과 개체당(個體當) 엽면적(葉面積)과의 상관관계(相關關係)는 r=0.865, 개체당(個體當) 건중량(乾重量)과 개체당(個體當) 엽록소함량(葉綠素含量)과의 상관관계(相關關係)는 r=0.888로 고도(高度)의 상관(相關)이 인정(認定)되었으며, 개체당(個體當) 건중량(乾重量)과 개체당(個體當) 광합성능력(光合成能力)과의 상관관계(相關關係)에서는 r=0.745로 비교적(比較的) 높은 상관(相關)이 인정(認定)되었다. 1년생(年生) clone의 엽부위별(葉部位別) 엽단위면적당(葉單位面積當) 광합성능력(光合成能力)과 엽록소함량(葉綠素含量)은 엽순서(葉順序)가 증가(增加)함에 따라 증가(增加)하여 28번째와 33번째 엽(葉)에서 각각(各各) 최대치(最大値)를 보였으며 그후 아래엽(葉)으로 내려올수록 감소(減少)하는 경향(傾向)을 보였다. Clone 68-1-54, 66-26-55, 65-22-11 등(等)은 개체당(個體當) 엽면적(葉面積), 단위면적당(單位面積當) 엽록소함량(葉綠素含量) 및 광합성능력(光合成能力)으로 보아 다른 clone들 보다 양호(良好)한 생장능력(生長能力)을 보였다. 제일대잡종(第一代雜種) 포플러, Populus alba${\times}$Populus glandulosa $F_1$ 유시(幼時) 생장량(生長量)은 개체당(個體當) 엽면적(葉面積)이나 개체당(個體當) 엽록소함량(葉綠素含量)으로 추정(推定)할 수 있었으며, 이러한 사실(事實)로 보아, 엽면적(葉面積)과 엽록소함량(葉綠素含量)의 측정치(測定値)는 본(本) 잡종(雜種) 포플러의 우량(優良) clone을 선발(選拔)하는 하나의 기준(基準)으로 사용(使用)될 수 있다. To select the superior clones of Populus alba ${\times}$ Populus glandulosa $F_1$, growth and some growth-related physiological characters were examined for thirteen, one-year-old and fifteen, two-year-old clones, respectively at the Seoul National University nursery in Suweon, Clonal differences in growth (total dry weight per tree), leaf area per tree and leaf chlorophyll content per tree at tow-year-old plots were highly significant at the 1% level, but not at one-year-old plots, Highly significant correlation was found between leaf area per tree and total dry weigh per tree (r=0.865), between leaf chlorophyll content per tree and total dry weight per tree (r=0.888), and between photosynthetic ability per tree and total dry weight per tree (r=0.745). The photosynthetic ability and leaf chlorophyll content per unit leaf area of one-year-old plant increased with increasing leaf order number from top. reached maximum value in the twenty-eithth and thirty-third leaves, respectively, and then decreased gradually from those leaved to base, Clones 68-1-54, 66-26-55 and 65-22-11 showed test growth based on leaf area per tree, leaf chlorophyll content per unit leaf area and photosynthetic ability of leaf tissue per unit area. Growth yield of populus alba ${\times}$ P. glandulosa $F_1$ clones could be estimated from either leaf area per tree of leaf chlorophyll content per tree. Therefore, measurements of leaf area and leaf chlorophyll content appear useful to select superior populus clones early growth.

SO₂에 대한 내성수종(耐性樹種)의 선발(選拔)을 위한 기초연구(基礎?究) - I. 엽조직(葉組織) 실험(實驗) -

김갑태,Kim, Gab Tae 한국산림과학회 1988 한국산림과학회지 Vol.77 No.2

To select $SO_2$-resistant tree species, leaf disks of 6mm in diameter, cut from the leaves of 6 species (Wistaria floribunda, Magnolia obovata, Rosa multiflora, Liriodendron tulipifera, Robinia pseudo-acacia and Acer palmatum) were floated on 25ml of testing medium and placed on laboratory under fluorescent lamp (1,500 Lux) for 20 hours. Chlorophyll content and acidity of the testing medium were measured. Testing medium was prepared by diluting $H_2SO_4$, $H_2SO_3$ and $Na_2SO_4$ with distilled water for various stoichiometric $SO_2$ concentrations, 0, 25, 50, 100 and 250 ppm. Total chlorophyll content was more decreased after treatment than before treatment, and was decreased more severely in $H_2SO_3$ sources, followed by $H_2SO_4$ and $Na_2SO_4$, sources. Decreasing rate of total chlorophyll content was generally large in Acer palmatum. Magnolia obovata and Wistaria floribunda, and was relatively small in Rosa multiflora, Liriodendron tulipifera and Robinia pseudo-acacia. Decreasing rate of chlorophyll content may be useful index for judging susceptifility of the leaf to $SO_2$. The acidity of the testing medium was generally decreased after treatment, and it means that cell leakage was occurred during treatment. The differences in medium acidity between before and after treatment may be poot index for susceptibility of the leaf to $SO_2$ owing to the difference among tree species in development of leaf mesophyll, acidity maintaining mechanism and butter capacity of the leaf tissue. $SO_2$에 대한 내성수종(耐性樹種)을 선발(選拔)하기 위하여, 6수종(樹種)(등나무, 일본목련, 찔레, 튜울립나무, 아까시, 단풍나무)의 엽조직(葉組織)(직경(直徑) 6mm, 50개(個))을 $H_2SO_4$, $H_2SO_3$ 및 $Na_2SO_4$를 증류수로 묽혀 농도별(濃度別)(0, 25, 50, 100 및 250 ppm stoichiometric $SO_2$ concentration) 용액(溶液) 25ml에 띄워 실온(室?)에서 1,500 Lux(fluorescent lamp)하에서 20시간 처리한 후 엽록소함량(葉綠素含量)과 처리용액(處理溶液)의 산도변화(酸度變化)를 측정(測定)하였다. 총엽록소함량(總葉綠素含量)은 처리전(處理前)에 비해 처리후(處理后)에 감소했으며, 급원(給源)$H_2SO_3$에서 가장 심하고 다음으로 $H_2SO_4$, $Na_2SO_4$의 순이었다. 엽록소함량(葉綠素含量)의 감소율(減少率)은 대체로 단풍나무, 일본목련 및 등나무에서는 크게 나타났고, 찔레, 튜울립나무 및 아까시에서는 상대적으로 작았다. 엽록소함량의 감소율은 잎의 $SO_2$에 대한 감수성(感受性)을 나타내는 지표(指標)로 이용할 수 있을 것으로 보인다. 처리용액(處理溶液)의 산도(酸度)는 대체로 처리후(處理后)에 낮아졌으며, 이는 처리중(處理中)에 세포질누출이 있었음을 나타낸다. 처리전후(處理前后)의 용액(溶液)의 산도변화(酸度變化)는 수종별(樹種別)로 엽육발달정도(葉肉發達程度), 조직내(組織內) 산도유지기작(酸度維持機作) 및 완충능(緩衝能)이 상이하므로 $SO_2$에 대한 감수성(感受性)을 나타내는 지표(指標)로 이용(利用)하기는 부적당하다고 보여 진다.

김갑태,이돈구 ( Gab Tae Kim,Don Koo Lee ) 한국산림과학회 1988 한국산림과학회지 Vol.77 No.1

One-year-old seedlings of Ginkgo biloba were treated with various simulated acid rains(pH 2.0, pH 3.0, pH 9.0 and pH 5.0) to examine the effects of simulated acid rain on the chemical properties of the tested soil. The seedlings were grown in a pot(4500㎤)containing one of three different soils(nursery soil, mixed soil and sandy soil). Simulated acid rain was made by diluting sulfuric and nitric acid solution(H¹SO⁴: HNO³=3 : 1, V/V) with tap water and tap water(pH 6.4), and treated by 5mm each time for three minutes during the growing seasons(April to October 1985). Acid rain treatments were done three times per week to potted seedlings by spraying the solutions. The chemical properties of potting media were compared among three soil types as well as among the various pH levels. The results obtained in this study were as follows : 1. Exchangeable calcium and magnesium contents and base saturation of the soil decreased with decreasing pH levels of acid rain, and their decreasing rates were as follows : sandy soil was the highest, followed by mixed and nursery soils, However, exchangeable aluminum content rather increased as the pH levels decreased. 2. Available phosphate in the soil decreased as the pH levels of acid rain decreased. Its content increased in nursery soil, compared with those before acid gain treatment, Gut decreased in mined and sandy soils. 3. Soil sulfate and nitrate contents increased remarkably as the pH levels decreased, and the only significant difference in the sulfate was found among the pH levels. Soil sulfate content was the highest in nursery soil, followed by mixed and sandy soils.
