| Abstract: | Relative amounts of DNA and histone were determined by Feulgen microdensitometry and alkaline fast-green microdensitometry in differentiating tracheary elements in cultured explants of Jerusalem artichoke (Helianthus tuberosus L.) tubers. The absence of endopolyploidy in cultured artichoke tissue was confirmed, and the nuclei of tracheary elements were exclusively at the 2C level for both DNA and histones. |
