Flow cytometry

• Genome size estimation and the data utilization in plant systematics and ecology
• Large-scale ploidy level screening
• Reproduction mode detection
• Methodological issues (impact of secondary metabolites, analysis of non-fresh material)

Image cytometry, karyology

Numerical taxonomy

• Multivariate morphometrics and its uses in plant biosystematics
• Morphological variation at various spatial scales

Biosystematic studies of polyploid alliances

• Morphological, ecological, phenological, and reproduction differentiation of cytotypes
• Population cytotype structure at various spatial scales
• Sympatric occurrence of various cytotypes
• Evolutionary relationships in diploid-polyploid groups
