Karyological Studies in Root-Tip Cells of Cannabis sativa var. indica

抄録

Chromosomal study was carried in the dividing root-tip cells of Cannabis sativa (Family : Cannabinaceae). The diploid chromosome number of this species is 2n=20. Karyotype analysis reveals that all the 9 chromosomes in female somatic cells are metacentric and 1 chromosome is submetacentric whereas the X and Y chromosome in male cells is sub-metacentric. The Y chromosome is longer than X chromosome. The third pair bears the satellite.
