Karyotype and nor-banding of mitotic chromosomes of some Vitis L.
Almeida-Toledo and Foresti (1985) studied the NOR-banding pattern in 48 fish species of the Anostomidae, Sternopygidae, Parodontidae, Characidae and Cichlidae families, and found only one mark in all species.
NOR-banding were performed according to Howell and Black (1980) to visualize the nucleolar regions which were active in the last interphase.
