Lichen, Sulpher dioxide,Chlorophylldegradation
A total of 22 specimens of folioge and crustose lichens are collected from different localities of Latur city in the Marathwada region of Maharashtra state and examined critically in the laboratory. Seven species are identified chemotaxonomically.Parmotrema tinoctorum (Nyl.) Hale, is a genus of lichen belonging to the family Parmeliaceae, found to grow on the barks of varieties of angiospermic plants and also on the rocks. Effect of sulpher dioxide pollutant on the thallus of this species is studied on different samples. Deformation and blackening of some of the lichen thalli is quite noticeable. Degradation of chlorophyll pigments has been studied in various samples by using spectrophotometer. The result analysis shows that the percentage of degradation of chlorophyll pigment is maximum in heavy traffic areas and comparatively very negligible in the open areas. The phytoecologicalaspects of lichens are also studied.
