Isozyme variation in diploid tropical and octoploid subtropical-temperate species of Bulnesia
Isozyme variation for 14 enzyme systems was studied in two diploid tropical species of Bulnesia (Zygophyllaceae), B. arborea and B. carrapo, and in the subtropicaltemperate octoploid, B. bonariensis. The estimated proportions of polymorphic loci for the tropical species appear low, 28.6 percent and...
