Abstract

Abstract:

Karyotype analysis for the species Reineckia carnea (Andr.) Kunth of the mo-

notypic genus Reineckia Kunth is given for the first time. The number of chromosomes in

root-tip cell was found to be 38, which is in accord with those reported by most of the pre-

vious authors^{[5,7,8,9,11,12,]}. The somatic complement shows a slight variation in size, i.e., the 2,

3, 5, 6, 7th pairs of the chromosomes have submedian constrictions, while the other pairs

have median centromeres. The karyotype is therefore a rather symmetrical one, and accor-

ding to the chromosomal terminology defined by Levan et al^[4], the karyotype formula of

the species is 2n=38=28 m+10 sm. In spite of the presence of two nucleoli in the te-

lophase as observed by the authors and Noguchi^[8] as well, the two corresponding Sat-chro-

mosomes have not been found. Photomicrograph of the chromosome complement and idiog-

ram are given in Fig. 1 and 2 respectively.
