ESTERASE ISOZYMES IN GERMINATING SEEDS OF BRASSICA AND RAPHANUS

Abstract

Using the gel isoelectrofocusing method, esterase isozymes were analyzed, and compared for species relationships in two genera, Brassica and Raphanus. Results with Brassica showed that there is great isozyme variation among the species having A genome alone, as well as among species having different genome constitutions. All species of the C genome group differed distinctly from those of other genome groups. In the genus Raphanus, isozyme activity was increased in the autotetraploid rather than in the diploid.
