Evolution of Nuclear DNA Content in Secretory Trichome Cells ofSolanum NigrumL. During Their Formation

Caryologia, 1976
SUMMARYThe nuclear DNA content of secretory trichome cells of Solanum nigrum has been studied by microspectrophotometry from initiation of the trichome up to the fully differentiated and functioning organ. Some initials become 4C by endoreplication, while others remain 2C.
