DNA content of a chromosome of Trillium erectum: effect of cold treatment.
The DNA (Feulgen) contents of a specific cold-treated (3 degrees C) chromosome and of a control (25 degrees 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.
