Distribution of cytotypes and seasonal variation in the Odontites vernus group in central Europe

Popis výsledku v původním jazyce

Koutecky P., Tuleu G., Badurova T., Kosnar J., Stech M. & Tesitel J. (2012): Distribution of cytotypes and seasonal variation in the Odontites vernus group in central Europe. - Preslia 84: 887-904. Based on differences in chromosome number two cytotypeswere reported in the Odontites vernus group in central Europe by earlier studies. These cytotypes were also considered to correspond to two seasonal ecotypes that differ in phenology, morphology and ecology. In this study, we conducted a broad screeningof central European populations of the O. vernus group using flow cytometry and morphological analysis of characters underpinning the seasonal variation (number of internodes). We confirmed the existence of a widespread diploid (2n = 2x = 18) with a highbut variable number of internodes and an early-flowering tetraploid (2n = 4x = 40) with a low number of internodes occurring on fallows or as an agricultural weed. In contrast to previous studies, we discovered an additional type, which
