| Abstract: | Leaching of soil by simulated acid rain made soil acidified and base ions lost. If wheat seedlings were planted in such acidified soil, their C-metabolism and N-metabolism were restrained, and their soluble sugar and nitrogen contents reduced. The restriction of the acidified soil to C-metabolism and N-metabolism of the wheat root system was larger than that to those of stems and leaves. Tab 4, Ref 23 |
