Genetic divergence among species of the section Strombocarpa, genus Prosopis (Leguminosae)

We studied degree of variability and relationships among populations belonging to five species of the section Strombocarpa of the family Leguminosae, namely Prosopis ferox, P. torquata, P. pubescens, P. strombulifera and P. reptans, by isozyme electrophoresis. The genetic similarity between P. repta...
