OSTI ID:29102
A greenhouse study tested the effects of three acids and five metals on foliage of lodgepole pine (Pinus contorta var. latifolia) and Douglas-fir (Pseudotsugs menziesii) seedlings. The seedlings were treated with a single immersion of foliage into solutions of three acids (HCL, H2S04, and HN3) and five metal chlorides (ZnC12, CdC12, HgC12, CuC12, and PbC12) each at five different concentration levels. Injury to the foliage was recorded after 5 weeks by counting needles that were chlorotic (yellow) or dead. Statistically significant (p < 0.05) effects were observed for both acids and metals. The effects of metals were far greater than the effects of acids for both species.
