Determination of Chromosome Numbers and Genome Sizes in Six Species of <i>Byblis</i> (Byblidaceae)

Chromosome numbers and 2C-values of six Byblis species were determined to investigate the chromosome differentiation genome diversity in this genus. Somatic B. liniflora complex showed diploid tetraploid 2n=16 32. In contrast, number gigantea, which belongs gigantea complex, displayed only 2n=36. The 2C DNA contents across all studied over a three-fold range, from lowest value 2C=0.64 pg rorida highest 1.93 gigantea. Since two cytotypes with different ploidy levels seen filifolia, 0.70 1.81 measured (2n=2x=16) (2n=4x=32), respectively. Haploid sizes filifolia were, thus, 1.3 times larger than that diploid. haploid 1Cx=271 Mbp was shown guehoi.
