An investigation of the possibilities of the use of phenols in chromosome analysis

È stato sperimentato l'acido gallico nella sua ázione sui cromosomi delle radici di Allium. Il tempo e le concentrazioni per indurre frammentazioni cromosomiche sono diverse a seconda che le radici siano tagliate o intatte, essendo in quest'ultimo caso più resistenti per l'integrità delle condizioni fisiologiche generali. Certe concentrazioni possono facilitare lo studio della morfologia cromosomica. La frammentazione dei cromosomi è indice non soltanto delle condizioni di subnarcotizzazione delle radici, ma nello stesso tempo anche dell'inizio di una condizione di letalità.

gallic acid: Its importance in cytochemical studies

Root tips of monocotyledons were soaked 2.5-3.0 hours at 25-27° C. in saturated aqueous coumarin solution and stained in a mixture of N HC 1 and 2% aceto-orcein (1:9 by volume) 3-4 seconds over a flame. They were then squashed in 1% orcein under a cover glass, the excess stain blotted and the cover sealed. Preparations could be kept about one week. Good chromosome morphology was secured. © 1953 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
