초록
본(本) 연구(硏究)는 전주(全州)-군산간(群山間) 국도변(國道邊)에 열식(列植)된 20년생(年生) 왕벚나무에 대하여 식수대폭(植樹帶幅), 엽록소(葉綠素), Mg, 그리고 Na 함유량(含有量)을 분석(分析)하여 대기오염과 벚나무 성장(成長)과의 관계(關係)를 조사(調査)하였다. 선정(選定)된 전주(全州)-군산간(群山間) 국도변(國道邊) 양측(兩側)(좌(左), 우(右)) 10개의 지점(地點)에서 각(各) 지점(地點)당 5그루 씩 총(總) 100주(株)에 있어서 수관중간부위(樹冠中間部位) 성숙엽(成熟葉)을 분석재료(分析材料)로 한 것은 전보(前報)와 같다. (1) 기록상(記錄上) 전주(全州), 이리(裡里), 군산지역(群山地域)은 주로 편서풍(偏西風)의 영향(影響)을 받고 있으며, (2) 수고(樹高)는 평균(平均) 5.7m, 흉고직경(胸髙直徑)은 25~30cm의 범위를 보였고 도로우측수목(道路右側樹木)의 흉고직경(胸髙直徑)이 좌측수목(左側樹木)의 흉고직경(胸髙直徑)보다 더 크게 나타났으며, 수관폭(樹冠幅)은 5.5~7.5m, 지하고(枝下髙)는 1.3~1.4m였다. (3) 식수대(植樹帶)의 평균폭(平均幅)은 160~170cm였다. (4) 총(總) 엽록소(葉綠素) 함유량(含有量)은 전주(全州)-이리간(裡里間)이
This report succeds the previous paper, the source of materials and statistical designs used were not altered. Under the hypothesis of maleffect of atmospheric pollutions emitted mainly by traffic automobiles on 20-year-old, Prunus yedoensis roadside trees planted along national road between Cheonju abd Kunsan, chlorophyll a and b contents, magnesium and sodium contents of leaves were analysed on September 15. Besides control sites considered to be a pollution free district, 20 polluted road-side sites, 10 on left roadside and 10 on right roadside, oppositely faced in pairs were selected. The leaves collected from 5 trees at each sampling site were bulked to eliminate the individual tree variation. Chlorophyll were extracted by Mackinney and Arnon method. The results obtained are as follows : 1. The planting belt width between road shoulder and paved road face edge for cherry trees, 160~170cm, was considered too narrow for the growing space. 2. On an average, the total chlorophyll content between Cheonju and Iri(
