公害 指標植物 들깨의 GAS 障害에 관한 硏究 = Studies on the Mechanism Injurious Effects of Toxic Gas on Perilla frutescens

국문 초록 (Abstract)

本 試驗은 1992年 4月부터 日本 三重大學生物資源學部 實驗圃場에서 公害에 비교적 약한 것으로 알려진 들깨(Perilla flutescens)의 6品種을 供試作物로 하여 1ppm, 0.5ppm 및 0.1ppm 등 낮은 濃度의 SO₂ gas를 開花結實期에 間歇的으로 20時間 處理하여 公害 地表植物로서의 利用 可能性이 있는지에 관한 試驗으로서 다음과 같은 몇가지 結果를 얻었다.
1.SO₂ gas 處理에 있어서 濃度 1ppm까지 에서는 葉綠素를 비롯한 莖徑, 穗數 및 光合成能力 等 거의 全 調査項目에서 有意性이 인정되었고, 0.5ppm 處理에 있어서도 葉綠素, 草長, 節數 및 穗數 等에서 有意性이 있었다.
2.SO₂ gas 處理에 따른 油脂含有率이나 脂肪酸 造成에 관한 差異는 없었다.
3.品種間에 있어서는 金海在來 및 紫蘇가 SO₂ gas에 대한 반응이 큰 品種으로 나타났다.

다국어 초록 (Multilingual Abstract)

A study was conducted to investigate useful possibility by air pollution indicator plant of perilla, and six varieties of perilla were intermittently treated during twenty hours by low concentration SO₂ gas (1ppm, 0.5ppm and 0.1ppm) in flowering and maturing stage, and this experiment was performed in Faculty of Bioresources, Mis University, Japan from April 1992.
The results obtained were as follow:
1. Chlorophyll content, stem diameter, photosynthesis and almost characters were showed significant difference in SO₂ gas treatment of 1ppm concentration, and chlorophyll content, plant length, number of node and number of cluster were showed significant difference at also SO₂ gas treatment of 0.5ppm concentration.
2. In oil content and fatty acid composition, there was not showed significant difference by SO₂ gas treatment.
3. Kimhae and Andong local varieties and perillae folium were showed sensitive response about SO₂ gas treatment.
