In this study, CPD (combined PI and DAPI) staining experiments were carried out in 16 plant species, followed by sequential FISH with 45S rDNA probe. The results revealed that rDNA sites were always shown as red CPD bands on chromosomes, demonstrating that the detection sensitivity of CPD staining is similar, to that of FISH. In Hordeum. vulgare and Allium cepa the known non-rDNA GC-rich regions together with their rDNA sites were
