Estudios fenético de las especies argentinas de la familia Bignoniaceae

Abstract

THE PHENETIC RELATIONSHIPS OF 37 SPECIES BELONGING TO 18 GENERA OF BIGNONIACEAE GROWING IN ARGENTINA WERE INVESTIGATED BY CLUSTER ANALYSIS (UPGMA) AND BY ORDINATION (PRINCIPAL COORDINATE ANALYSIS). FORTY-EIGH CHARACTERS, 30 MORPHOLOGICAL, FOUR ANATOMICAL, THREE ECOPHENOLOGICAL AND 11 ON NECTAR FEATURES WERE ANALYZED IN THIS STUDY. CORRELATION AND DISTANCE PHENOGRAMS SHOWED SOME DIFFERENCES IN THE ASSOCIATION OF TAXA. IT IS. HOWEVER, THE PRINCIPAL COMPONENT ANALYSISI THE ONE THAT BEST INDICATES THE NATURAL GROUPS WITHIN THE FAMILTY, MATCHING NOT ONLY THE CURRENT TAXONOMY BUT ALSO SOME ECOLOGICAL ASSOCIATIONS FOR THE SPECIES ANALYZED. THE RSULTS FROM THIS STUDY DO NOT JUSTIFY ANY GENERIC MERGERS.
