Karyotype studies of endemic species Moehringia grisebachii (Caryophyllaceae) from Sredna Gora Mts, Bulgaria
Keywords:
Bulgaria, chromosome number, karyotype, Moehringia grisebachii, Sredna GoraAbstract
The chromosome number and karyotype of the Balkan endemic species Moehringia grisebachii are described for the first time. Plant material was collected from 10 populations spread in Sredna Gora Mts., Bulgaria. Basic chromosome number x= 12 and diploid chromosome number 2n = 24 have been established. Metacentric and submetacentric chromosomes have been registered with the metacentric ones being dominant. Differences have been found among the studied populations in the chromosome size and morphology. Microphotographs of somatic metaphase plates and idiograms of all studied populations are presented.
