Abstract

CHROMOSOME NUMBER AND NUCLEOLAR ORGANIZER IN Chioris gayana (KUNTH) The methodology used in Graminae for chromosome counting in mitotic cells and their related morphological observations was adapted. Adventitious root tips were used pre-treated with colchicine and maceration in pectinase. In all the analized cells a regular mitotic process with, a chromosome number 2n - 20 and a pair of homologous satellized chromomes was observed, which was related with the existence of an unique nucleolus. The basic chromosome number of Chioris gayana (Kunth), "Rhodes grass" is x - 10 ant it has, as observed a pair of satellized chromosomes with only one nucleolar organizer.
