A CHEMOSYSTEMATIC SURVEY ON WILD RELATIVES OF BRASSICA-OLERACEA L

AGUINAGALDE, I., GOMEZ‐CAMPO, C. & SANCHEZ‐YELAMO, M. D., 1992. A chemosystematic survey on wild relatives of Brassica oleracea L. A study on 12 taxa of n= 9, wild Brassica species (including wild B. oleracea) has led to the detection of 21 different flavonol‐glycosides. Differential patterns have been obtained for each taxon. Seed proteins and five isoenzyme systems have been analysed by polyacrylamide gel electrophoresis. The presence of many bands common to ail species was the rule for seed proteins, but differences in polypeptide contents were observed. There were also clear qualitative differences in isoenzyme patterns. Interspecific differences were examined by including those phytochemical characters in a numerical analysis. While the maximum morphological variability occurs in Sicily, phytochemical diversity seems to be maximum further east, in the B. cretica group. Copyright © 1992, Wiley Blackwell. All rights reserved
