Abstract
C. roseus, which is commonly used as an ornamental plant, is also well-known for its medicinal value in the treatment of diabetes, ang more notably, of cancer. thus, a cytological study of this play ' be very valuable in the breeding of improved species and would provide useful data for the production of better cultivars with greater medicinal value. This study aimed to determine the chromosome number of the plant found in UPLB, and to characterize its chromosomal traits. cetocarmine squash technique revealed the chromosomes of the somatic cells of C. roseus. The karyotype analysis showed the modal chromosome number was 2n = 16. Based on the position of the centromere these chromosomes consisted of three groups: those with median submedian and subterminal centromeres. Some cells had chromos numbers of 2n = 12 and 14. The mitotic index of the cells was 22.06%.
