Intraspecific differentiation of Reed Grass Calamagrostis arundinacea (L.) Roth (Poaceae) populations revealed by peroxidase allozymes

Maria Krzakowa, Zbigniew Celka

Abstract


The genetic Variation of Reed Grass Calamagrostis arundinacea (L.) Roth was investigated in 25 populations in various geographic regions of Poland. A total of 907 individuals were sampled for electrophoretic analysis of peroxidase loci (11 allozymes). Populations were characterised by genetic parameters e.g. heterozygosity level, Wright's fixation index (F) and polymorphism coefficient (Pg). Mean values of interpopulation variability level (GST=0.0310), total genetic diversity (HT=0.4102) and gene flow between populations (Nm=7.805) were also examined. All the populations were polymorphic and they remain in Hardy Weinberg equilibrium.
