Microgeographic differentiation in a Cyclobalanopsis glauca population in western Huangshan, Anhui Province

Chen Xiao Yong and Song Yong Chang (Department of Environmental Sciences, East China Normal University, Shanghai 200062)  
Microgeographic differentiation in a Cyclobalanopsis glauca (Thunb.) Oerst. population in western Huangshan was examined using vertical slab polyacrylamide gel electrophoresis. No significant differences of allelic frequencies were detected between two subpopulations. Mean gene diversity in subpopulations was 0.1826, and significant deficiencies of heterozygotes were found at 2 and 1 loci in Xiaoling and Diaoqiao subpopulation, respectively. There occurred very low differentiation between the two subpopulations (G ST =0.976%). It might be due to homogenous microhabitats and high gene flow (mean Nm was 17.3).
