Isozyme variation in Bulnesia retama, B. schickendantzii and B. foliosa (Zygophyllaceae)

The genetic variation between two allopatric populations of Bulnesia retama and that of B. schickendantzii and B. foliosa was investigated. The Peruvian population of B. retama showed low values of P (0.117) and He (0.057) compared to those in the Argentine population wich P = 0.59 and He = 0.269; B...
