This experiment was conducted to determine the responses of some pine species to acidity of cultured soils, and absorption behavior of alkaline elements and to observe the growth characteristics during afforesting period. The results were summarized as follows. 1. Total dry weight indicating growth volume was not much influenced by the acidity of cultured soils (pH 4∼8) in all of the 4 species studied. Pinus koraiensis showed more dry weight than any other species, which indicated statistically significant difference. 2. T-R ratio of dry weight was not much affected by the acidity of cultured soils (pH 4∼8) and the difference of cultured soils (pH 4∼8) and by species. Growth phase also did not show remarkable change through the experiment period. 3. The average sodium content ratio in the plant body had no correlation with cultured soils (pH 4∼8), bue significant differences were recognized among species statistically. 4. It was found that sodium content ratio was not much influenced by the cultured soils (pH 4∼8), even when the tops and roots were separately analyzed. But, very significant difference was found among the species. Pinus koraiensis especially, showed greater volume growth maintaining low sodium content ratio than any other species, which indicates that Pinus koraiensis has unfavorable characteristics for growing on the seaside.
