Abstract

Douglas firs (Pseudotsuga menziesii [Mirb.] Franco) are suffering strongly from air pollution in western Europe. We studied the effect of low concentrations of ozone (200 micrograms per cubic meter during 3 days) and sulfur dioxide (53 micrograms per cubic meter during 28 days) on translocation of assimilates in 2 year old Douglas firs. The trees were exposed to the pollutants and afterward transferred to a growth chamber adapted to the use of (14)CO(2). Root/soil respiration was measured daily. The results showed a significant decrease of the (14)CO(2) root/soil respiration during the first 1 to 2 weeks after exposure to either ozone or sulfur dioxide. The ultimate level of (14)CO(2) root/soil respiration did not differ significantly, which suggests a recovery of the exposed trees during the first weeks after exposure.

摘要

在西欧，道格拉斯冷杉（Pseudotsuga menziesii [Mirb.] Franco）深受空气污染之害。我们研究了低浓度臭氧（3 天内每立方米 200 微克）和二氧化硫（28 天内每立方米 53 微克）对 2 年生道格拉斯冷杉同化物转移的影响。这些树木暴露在污染物下，然后转移到一个适应使用 (14)CO(2)的生长室。每天测量根/土壤呼吸。结果表明，在暴露于臭氧或二氧化硫后的头 1 至 2 周内，(14)CO(2)根/土壤呼吸明显下降。最终的 (14)CO(2)根/土壤呼吸水平没有显著差异，这表明暴露后的树木在暴露后的头几周内得到了恢复。
