Electrophoretic study and genetic affinity in the Campanula elatines and C. fragilis (Campanulaceae) rock-plants group from Italy and W. Jugoslavia

Variability and genetic divergence of 11 field populations of seven species of the Campanula elatines and C. fragilis rock-plants group from the Mediterranean and pre-Alpine areas have been studied by starch-gel electrophoretic techniques. Campanula isophylla, C. elatines, C. elatinoides, C. fragilis subsp. fragilis and subs. cavolinii, C. garganica were collected in Italy, whilst C. fenestrellata subsp. istriaca and C. portenschlagiana came from W. Jugoslavia. Twelve enzymatic loci for each population were genetically analysed: PGI-1 and 2, PGM-2, IDH-1 and -2, SKDH, ME, ADH, GOT-2, MPI-1 and -2, SOD-1. The genetic distances among the above mentioned entities have been calculated by Nei's index and depicted in a dendrogram.
