To determine the effects of light intensity and fertilization level on shoot growth and leaf, chlorophyll content, of Zanthoxylum schinifolium, Ginkgo biloba, Elaeagnus umbellata and sxLigustrum obtusifolium, shoot growth and monthly change of leaf chlorophyll contents were measured and compared. Leaf chlorophyll content of four species were increased with leaf growth, showed highest value on late August, and were decreased after that time. More leaf chlorophyll content and duration on late September were found in intensive fertilization plots. The less light intensity was illuminated, the more leaf chlorophyll content of Zanthoxylum schinifolium, Ginkgo biloba and Ligustrum obtusifolium were measured. The more light was illuminated, The more leaf chlorophyll content of Elaeagnus umbellata were measured on late May, June and July. The less light intensity and more fertilization were treated, the more shoot growth of Zanthoxylum schinifolium and Ligustrum obtusifolium were measured. The more fertilization were treated, the more shoot growth of Ginkgo biloba and Elaeagnus umbellata were measured. However, Shoot growth of Ginkgo biloba and Elaeagnus umbellata were not significantly differed between light intensity. Highly significant correlations between shoot growth and leaf chlorophyll content of Zanthoxylum schinifolium was proved throughly, and significant correlations of Ligustrum obtusifolium was proved partially. Correlations between shoot growth and leaf chlorophyll content of Ginkgo biloba and Elaeagnus umbellata was proved not significant.

몇 소나무類의 葉綠素 含量의 月別 變化

李慶學,金甲泰,朱洸영,曺炅眞,李敦求 서울大學校 農科大學 1985 서울대농학연구지 Vol.10 No.2

植物體는 生存 또는 生長을 위해 光合成作用을 하며, 綠色植物은 이를 위한 色素로서 葉綠體를 가지고 있다. 따라서 이의 含量은 生長能力이나 各種 stress에 대한 生理的 活成變化를 나타내는 指標로 이용되는데 이에 對한 硏究報告는 基礎的 資料로서의 重要性에도 불구하고 林木 특히 소나무類에 있어서는 극히 드물었다. 이에 서울大學交 農科大學 構內에 있는 소나무類 5樹種에 對한 針葉單位生重量當 葉綠素含量을 月別測定한 結果 樹種間의 含量差異는 뚜렷하니지 않았으나 測定時期間에는 差異를 보였다. 總葉綠素의 含量變化는 葉綠素 a의 含量變化에 起因하며 이는 여름철에는 높고 겨울철에는 낮았다. 또한 最大値는 2年生 針葉을 7, 8月에 測定했을 때 나타났다. 이러한 結果를 綜合해 볼 때 소나무類의 生理的 生活은 葉綠素 a와 密接한 關係를 갖고 있는 것으로 思料된다. To obtain the fundamental data about the chlorophyll contents of some conifers, monthly measurements of them per unit fresh weight(g) of needles were performed. The results were summarized as follows. 1. Difference of total chlorophyll contents between measuring times in a species was clear but not between species. Total chlorophyll content in summer showed high value and that in winter did low value. 2. In general, the total chlorophyll contents of the conifers showed the highest values in two-year-old needles, measured in July or August. 3. Monthly change of total chlorophyll contents was mainly due to that of the contents of chlorophyll a, and the contents of chlorophyll b was not varied greatly with measuring times. 4. It seems that the physiological activity of needles was closely related with the contents of chlorophyll a.
