چکیده انگلیسی
Fresh leaves of 150 individuals from 15 populations representing five putative species of Stachys sect. Fragilicaulis, subsect. Fragiles distributed in the Zagros mountains in western Iran were analyzed for isoenzyme variation. Four enzyme systems (peroxidase, esterase, superoxide dismutase and ascorbate peroxidase) have been studied and a total of 32 bands representing seven putative loci have been analyzed by UPGMA using the Euclidean distances. UPGMA analysis resulted in the recognition of three distinct clusters among the considered populations. The average value of Shannon diversity index (Hâ²) estimated for each population ranged from 0.05 to 2.17. The mean number of bands per isoenzyme ranges from 1.60 to 2.50. The value of Euclidean distance ranges from 0.85 to 3.79. The analysis of isoenzyme variation patterns suggests recognizing following species in Stachys sect. Fragilicaulis subsect. Fragiles: Stachys benthamiana (including Stachys megalodonta), Stachys kurdica (including Stachys ballotiformis) and Stachys asterocalyx. These data also suggest paying more attention to geographical distribution of taxa in Stachys for their taxonomic delimitation. This study provides another strong support for application of electrophoretic analysis of isoenzymes in taxonomy at species level.
