Lichens on Nature Trail in Plant Genetic Conservation Project, Rambhai Barni Rajabhat University, Chanthaburi Province

Abstract

In order to classify the lichens on nature trail in Plant Genetic Protection Area, Rambhai Barni Rajabhat University, Chanthaburi province. Lichens were collected from bark of trees during January to May, 2015. A line transect of 480 meters long on the nature trail was used. Samples were collected every 20 meters on both sides of the line. Lichens from tree bark were collected in 2 x 2 m² quadrate at each sampling station. The specimens were taxonomically classified based on morphological, anatomical and chemical constituent substances. The chemical compositions were analyzed by spot test and thin layer chromatography (TLC) in laboratory. The total of 110 lichen specimens were classified into 9 families, 15 genera and 31 species. The families with the highest number of samples were Graphidaceae (61 percent of the total specimens), followed by Malmideaceae, Pyrenulaceae, Coenogoniaceae, Arthoniaceae, Monoblastiaceae, Ramalinaceae, Trypetheliaceae and Physciaceae consisted of 15, 13, 3, 2, 2, 2, 2 and 1 percent, respectively.
