Abstract
Sections of a thickness of 15 β cut from unfixed material by means of a freezing microtome were treated for 1 hr with 0.2% aqueous solutions of a number of fluorochromes. Under normal microscopical conditions no uniform staining pattern could be observed. With the aid of an ultraviolet microscope, however, one type of fluorescence pattern became apparent. In all cases observed the thickened gelatinous secondary cell walls of tension wood showed a remarkable lack of fluorescence; this in marked contrast with a very distinct fluorescence exhibited by the primary cell wall and by both primary and secondary cell walls of normal wood.
