Abstract

The DNA (Feulgen) contents of a specific cold-treated (3°C) chromosome and of a control (25°C) were measured by means of photographic-plate microdensitometry. Despite marked morphological alterations in the cold-treated B chromosome of Trillium erectum, its DNA content was unchanged from that of the control.
