In this study, the changes in
photosynthetic pigment contents of epiphytic foliose lichens Parmelia sulcata
and Parmelina tiliacea collected on the trunk of oak trees in each one of four
different localities in Bursa Province were investigated. Almost all of the
photosynthetic parameters of P. sulcata in all the localities were measured
higher than in P. tiliacea. Chlorophyll and carotenoid contents, and
phaeophytinization rate measured in thalli of P. sulcata showed significant
differences between the localities. Only chlorophyll b/a ratio and
phaeophytinization rate in thalli of P. tiliacea was not significant between
the localities. Other parameters showed significant differences. The highest
photosynthetic pigment contents and ratio for each lichen species was measured
in samples collected from 3th locality. The lowest chlorophyll a content and
phaeophytinization rate for each lichen species were measured in samples
collected from 2nd locality. Compared to variations in the chlorophyll a, total
chlorophyll, and total carotenois content for each lichen species between the
localities were found statistically significant at level P<0.01. P. sulcata was the better as an indicator of environmental quality than P. tiliacea. Keywords: Epiphytic lichen, Photosynthetic pigment, P><0.01
