The examination of the nucleic acids in the contents of the anthers (microsporocytes and tapetum) has shown, that the onset of the prophase I and the beginning of the crumbling of the tapetum-cells a decrease in the amount of DNA takes place from 1,1 % of the dry weight to ca. 0,5 %. In the interphase I the amount of DNA returns to the original level. At the time of the depression the appearance of nucleic acid-components in the contents of the anthers can be shown by paper-chromatography. It is assumed, that a transfer of DNA takes place from the tapetum to the microsporocytes by means of the DNA-components.
