The NOR and nucleolus in the spermatogenesis of Psylla alni (L) (Homoptera) analysed by silver staining
Languages of publication
Ag-staning of permatocytes of Psylla alni (2n=25) suggests that the <nucleolus> organizer regions (NOR) are present in a pair of medium size autosomes. NOR activity was observed throughout the meiotic prophase including diakinesis.
