The method of analysis of the leaf blade anatomical structure of narrow-leaves fescues on example of populations of Festuca valesiaca agg. (Poaceae)

Abstract

Iryna O. Bednarska

In the taxonomy of narrow-leaves Festuca species, the leading diagnostic criteria are characteristic of leave anatomy structure. In order to study their variability in difficult taxonomic groups, author method was developed. On the example of F. valesiaca agg., the approaches and criteria for the analysis of 13 anatomical features was described. These methods can be applied for comparative analysis of the variability of populations different species of the genus. In combination with morphometric parameters, the method provide grounds for the detection of ecological and geographical differentiation of species and the degree of overlap of diagnostic parameters in the populations of critical taxa.
