KARYOLOGICAL STUDY OF GENUS ATRIPLEX L. IN BULGARIA
NELI H. GROZEVA
Abstract: The study is a part of a multi-annual research on family Chenopodiaceae within the Bulgarian flora and aims to investigate the karyotype morphology of taxa from Atriplex. The karyotype morphology of eight species – Atriplex hastata L., A. heterosperma Bunge, A. hortensis L., A. nitens Schkuhr, A. oblongifolia Walds. & Kit., A. patula L., A. rosea L., A. tatarica L. from Bulgarian populations was reported for the first time. Two chromosome numbers: 2n = 2x = 18 and 2n = 4x = 36 have been found in the genus Atriplex. The karyotypes of the investigated populations consist of metacentric and submetacentric chromosomes and in one of the studied populations of A. nitens were established chromosomes with satellites. The idiograms of all studied populations were illustrated.
