Abstract
AbstractChromosome number, meiotic behaviour and morphological characters related to habit were studied in 10 populations of Scutellaria platystegia Juz. from S. sect. Lupulinaria native to Iran. All populations are diploid and has the chromosome number 2n = 2x = 22, which is consistent with the proposed base number of x = 11. This taxon displayed regular bivalent pairing and chromosome segregation at meiosis. However, some meiotic abnormalities observed included various degrees of fragmented chromosomes, laggards and bridges in anaphase I to telophase II, precocious division of centromeres in metaphase I or II, asynchronous nucleus and cytomixis. We evaluated and determined the population limits within S. platystegia, employing multivariant statistics. We found a striking association between meiotic behaviour and gross morphology.
