The objective of this study is to compare the physiological response (content and degradation of photosynthetic pigments, membrane oxidation products and soluble proteins) and multi-element content of Ramalina celastri (lichenized fungi) growing on agricultural fences with no-tillage (associated with transgenic crops and agrochemical application), organic cropping and a non-cultivated area. We found that R. celastri did not differ in its physiological response to agricultural practices, except for the contents of chlorophyll b and phaeophytin a which were high in both cultivated areas. Lichens growing in organic cropping fields have higher arsenic, chromium, uranium and internal transition elements common in the earth’s crust, possibly due to the greater resuspension of the material during soil tillage. Lichens that grow on posts close to no-tillage field had higher bromine contents (present in numerous pesticides). We found evidence that R. celastri behaves as a tolerant species to air pollution in agricultural environments.

在农业篱笆上生长的地衣的生理响应和多种元素含量：免耕和有机耕作比较的先导研究。

这项研究的目的是比较在免耕（与转基因相关的农业围栏）上生长的Ramalina celastri（地衣真菌）的生理响应（光合色素，膜氧化产物和可溶性蛋白的含量和降解）和多元素含量。作物和农药的应用），有机作物和非耕地。我们发现，[R 。塞拉斯特里除了在两个耕种地区都很高的叶绿素b和Pheophytin a含量外，其对农业实践的生理反应没有差异。在有机耕作田中生长的地衣具有较高的砷，铬，铀和地壳中常见的内部过渡元素，这可能是由于该材料在土壤耕作过程中具有更大的重悬浮性。在接近免耕田的地方生长的地衣中的溴含量较高（存在于许多农药中）。我们发现R的证据。celastri在农业环境中表现出对空气污染的耐受性。
