光 環境要因이 잣나무 幼苗의 體內 無機養科 變化에 미치는 影響에 關한 硏究 = Effects of Light Environmental Factors on the Change of Inorganic matter of Pinus Koraiensis Seedlings

다국어 초록 (Multilingual Abstract)

Pinus Koraiensis seedlings were grown under different relative light intensity on the Seedling bed and transplanting bed to measure the change of inorganic matters by the light environmental factors. The results obtained were summarized as follows:
1. Total inorganic matters(nutriment)contents of various parts of seedlings were generally irregullar. N, P₂O_5, K₂O, CaO, MgO and Fe increased with increasing relative light intensity and decreased with decreasing relative light intensity While Mn had a tendency to be exceptional conversely.
2. In the Change of inorganic matters by the seedling organs, M, P₂O_5, K₂O, CaO and Mn were showed the highest in the leaves, MgO in the stems. Fe was the most contents rate in the roots.
3. N, P₂O and K₂O were more in one year old leaves and MgO was in the 2 year-old leaves than the other autriment, in the change of inutriment contents rate by the leaves age, CaO, Fe, Mn were the highest in the 3-year-old leaves.
