Response of yellow-poplar ( Liriodendron tulipifera L.) seedlings to simulated acid rain and ozone—2. Effect on throughfall chemistry and nutrients in the leaves
Each week 1-year-old yellow-poplar seedlings grown in a greenhouse were fumigated with 0.0, 0.05, 0.1, or 0.2 μl/l ozone (O 3) for 8 hr on 3 consecutive days and treated once with 1.25 cm simulated acid rain of pH 5.5, 4.0, and 3.0. Effects of O 3 and acid rain on throughfall chemistry after 16 week...

| Summary: | Each week 1-year-old yellow-poplar seedlings grown in a greenhouse were fumigated with 0.0, 0.05, 0.1, or 0.2 μl/l ozone (O
3) for 8 hr on 3 consecutive days and treated once with 1.25 cm simulated acid rain of pH 5.5, 4.0, and 3.0. Effects of O
3 and acid rain on throughfall chemistry after 16 weeks of treatment and on mineral elements in the foliage of seedlings harvested on 1 September were determined. Except for K, the concentration of elements detected in throughfall (K, Ca, Mg, Fe, and Zn) grew with increasing acidity of the rain solution. Foliar leaching of mineral elements by pH 3.0 rain was increased by high levels O
3. The concentration of most elements in yellow-poplar leaves was affected by O
3 or rain acidity. Rains of high acidity ( |
