Photosynthetic CO dependencies were measured for six lichen species, representing a variety of morphologies and collected from widely different habitats. All curves exhibited a linear increase in photosynthesis with increasing CO concentrations at the lower range of CO values, but little photosynthetic variation with increasing CO concentrations at the upper range of CO values. Half maximal CO concentration estimates varied from 147-440 μl CO·l, but had broadly overlapping confidence intervals. We conclude that lichen CO dependencies are basically similar to those reported for higher plants and discuss the reasons why widely varying results have previously been published.
对六种地衣物种进行了光合二氧化碳依赖性测定，这些物种代表了各种形态，且采集自广泛不同的栖息地。在较低二氧化碳值范围内，所有曲线均显示光合作用随二氧化碳浓度增加呈线性增加，但在较高二氧化碳值范围内，随着二氧化碳浓度增加，光合作用变化很小。半数最大二氧化碳浓度估计值在147 - 440微升二氧化碳·升之间，但置信区间有广泛重叠。我们得出结论，地衣的二氧化碳依赖性与高等植物报道的基本相似，并讨论了此前发表的结果差异很大的原因。
