Mn 과 Zn 이 소리쟁이 ( Rumex crispus L. ) 의 발아와 유식물의 (幼植物) 생장에 미치는 영향
이호준,윤영진 ( Ho Joon Lee,Young Jin Yoon ) 한국환경생물학회 1994 환경생물 : 환경생물학회지 Vol.12 No.2
The amounts of accumulation and the effects of manganese and zinc on the seed germination and the growth of seedlings were investigated in Rumex crispus L. after Mn and Zn treatments. The effects of Mn and Zn on the germination rate in R. crispus L. showed 84∼89% in the treatments of the below 50ppm in both Mn and Zn, whereas it showed 65% in 100ppm Mn and 79% in 100ppm Zn, which had a relatively high germination rate in high concentration. The relative growth rate in R. crispus L. exhibited a tendency of somewhat restrained growth in the higher concentration, but showed a good growth compared to control. The relative growth rate of length in R. crispus L. as concentrations of Mn and Zn increase from 5ppm to 100ppm revealed a tendency of somewhat restrained growth, but showed a good growth compared to control. The accumulation amount of Mn and Zn in organs of R. crispus L. showed a tendency to increase in order of its stem < leaf < root, and the more time passed by after its treatment and the higher the concentrations of its treatment were, the more amount of their accumulation appeared. These results suggest that R. crispus L. is not only strong in tolerance in the contaminated soil of Mn and Zn but contributable to the purification of the contaminated soil.

월성원자력발전소 주변의 삼림식생을 분석하기 위하여 1994년 4월부터 1994년 10월까지 식물사회학적 조사를 실시하였다. 또한 상관에 의해 현존식생도 및 녹지자연도를 작성하였으며, 순 1차 생산력과 식물현존량도 추정하였다. 군집조성표에 의한 삼림군락은 소나무군락, 곰솔군락, 굴참나무군락, 상수리 나무군락의 4군락으로 구분되었다. 각 군락의 주요 구성종으로는 소나무군락에서 소나무, 졸참나무, 털진달래, 맑은대쑥, 산거울, 곰솔군락에서 곰솔, 소나무, 진달래, 청미래덩굴, 굴참나무군락에서 굴참나무, 조록싸리, 큰기름새, 맑은대쑥, 댕댕이덩굴, 상수리나무군락에서 상수리나무, 갈참나무, 큼기름새, 그늘사초, 맑은대쑥 등이다. 현존식생도에 의한 삼림군락의 분포율은 곰솔군락이 40.3%로 가장 높고, 녹지자연도는 7등급이 60.0%로 가장 넓은 분포율을 보였다. 삼림토양의 pH는 4.45∼5.32, 유기물함량은 5.61∼6.34%의 범위로 나타났다. Montreal model에 의한 순 1차 생산력은 1,555.2g/㎡/yr, 식물현존량은 14,963.32ton/㎢로 추정되었다 The forest vegetation, estimation of phytomass and net primary production on the vicinity of Wolsong Atomic Power Plant were analyzed on the basis of the phytosociological data. And depending on physiognomy, actual vegetation map and the degree of green naturality(DGN) was drawn in 1:50,000 scale. According to Z-M method, the forest vegetation was classified into 4 communities; A. Pinus densiflora community, B. Pinus thunbergii community, C. Quercus variabilis community, D. Quercus acutissima community. Generally, Pinus densiflora, Quercus variabilis, in tree-1 layer, Quercus acutissima, Quercus variabilis, in tree-2 layer, Rhodedendron mucronulatum, Quercus serrate, in shrub layer, Artemisia keiskeana, Carex humilis, in herb layer, showed high coverage index. The pH and contents of organic matter of the forest soil collected in each sites were shown range of 4.45 to 5.32 and 5.61% to 6.34% in mean of communities respectively. The distribution rate in actual vegetation map were the highest in Pinus thunbergii community. The average DGN showed to 5.1. Net primary production and phytomass per unit area which estimated by Montreal model were assumed in 1,555.2g/㎡/yr, 14,963.32ton/㎢, respectively.
