Abstract
Dry matter production, net photosynthetic rate, leaf nutrient status and tr unk anatomical characteristics of Fagus crenata seedlings grown in brown fo rest soil acidified by adding H2SO4 solution were investigated. The soil ac idification leaded to decreased (Ca+Mg+K)/Al molar ratio in the soil soluti on. Dry mass per plant of the seedlings grown in the soil treated with H+ a t 120 mg.L-1 was significantly reduced compared with the control value at 0 mg.L-1. When net photosynthetic rate was reduced in the seedlings grown in the soil treated with H+ at 120 mg.L-1, the carboxylation efficiency and m aximum net photosynthetic rate at saturated CO2-concentration were lower th an the control values. The addition of H+ to the soil at 120 mg.L-1 induced a reduction in the concentration of Ca in the leaf. By contrast, the conce ntration of Al in the leaf was increased with increasing the amount of H+ a dded to the soil. The annual ring formed in the seedlings grown in the soil treated with H+ at 120 mg.L-1 was significantly narrower than that at 0 (c ontrol), 10, 30, 60 or 90 mg.L-1. Based on the results obtained in the pres ent study, we conclude that Fagus crenata is relatively sensitive to a redu ction in the (Ca+Mg+K)/Al molar ratio of soil solution compared with Picea abies.
