“…Therefore, flow cytometry (FCM) is a more convenient alternative for establishing the ploidy/genome size of the Orchidaceae species. The genome size is, next to morphological descriptions, and molecular methods, good taxonomic marker useful for identifying many problematic taxa and phylogenetic reconstruction of closely related species (Ávila Diaz & Oyama, 2007; Fajardo, De Almeida Vieira & Molina, 2014; Rewers & Jedrzejczyk, 2016; Ståhlberg & Hedrén, 2008; Soliva, Kocyanb & Widmera, 2008; Szczęśniak, Gola & Jedrzejczyk, 2017; Wang et al, 2016). In the literature, we can find results, which show correlation between 2C DNA amount and morphological, ecological parameters of many groups of plants (Ahmadian et al, 2017; Knight, Molinari & Petrov, 2005; Knight & Ackerly, 2002).…”
