Abstract:The total nuclear DNA amount (2C value) of 75 individuals of Krascheninnikovia ceratoides s. l. was assessed by flow cytometry in 16 populations. The mean 2C value in all samples ranged from 2.59 to 6.99 pg. The relationship between total 2C values and ploidy level was calibrated using chromosome counting in four populations. Diploids (2n = 18) and tetraploids (2n = 36) were revealed. In diploid plants, mean 2C value varied between 2.59 to 3.72 pg, in tetraploids − from 6.04 to 6.99 pg. The GS of diploids is a… Show more
