Abstract: Eleven species of the genus Allium belonging to the section Cepa, Phyllodolon, Rhizirideum, Melanocrommyum andAlliun ware investigated as to the presence of esterase isoenzymes by means of the gal isoelectric focusing which shows better resolution than polyaorylamide gel electrophoresis. In all examined species twenty six isoenzymes were found. The individual sections are well characterized by esterase isoenzymes revealed by this method, on the other hand, the differences, as shown by the Jaceard index, between the subganera are insignificant. Investigation of seven cultivars ofAllium cepa shows the isolated position of the cultivar Kaštická. These results are in full agreement with those found with use of the polyacrylamide gel electrophoresis and show the usefulness of gel isoelectric focusing for the solution of the chemotaxonomical problems. |
