First comparative phenetic studies of argentinean species of Acacia (Fabaceae), using morphometric, isozymal, and RAPD approaches

Morphological and genetic diversity among Acacia aroma, A. macracantha, A. caven, and A. furcatispina were studied with morphometric, isozymal, and RAPD approaches. The analysis of seven isozyme systems revealed 21 loci, and RAPD analysis showed 34 loci. Most of these loci allowed us to differentiat...
