Abstract
Microsporocytes of Tradescantia paludosa have been irradiated with ultraviolet microbeams of 2 to 10 microns. At a wavelength of 2570 A, we observe a selective destruction, total or partial, of the spindle in the first division, anaphase bridges and interruption in the second division.At a wavelength of 2750 A, the most remarkable effect is the "paling" of some parts of the chromosome structure as well as of interphase nuclei, and also stickiness bridges in the bivalents of the first division.
