Abstract
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.
摘要
通过照相底片显微光密度测定法测量了经过特定冷处理（3摄氏度）的染色体以及对照（25摄氏度）的DNA（福尔根）含量。尽管直立延龄草经过冷处理的B染色体有明显的形态改变，但其DNA含量与对照相比并未改变。
