Análisis cariotípico de Famatina andina (Phil.) Ravenna (Amaryllidaceae): primer registro de una Hippeastreae sudameri cana con constricciones secundarias centroméricas

ABSTRACT Bulbs were collected from a population of Famatina andina (Phil.) Ravenna in central Chile. Their chromosomes were analyzed and it was observed that the cariotypic formula and chromosomal number are identical to Famatina cisandina Ravenna. Secondary centromeric constrictions were also obser...
