KARYOLOGICAL STUDIES IN TEN DIFFERENT POPULATIONS OF DESERT LILY ALOE VERA FROM PAKISTAN

摘要

To enhance theoretical basis of Aloe feeding and provide cytological basement, the karyotype and morphology ofmitotic chromosomes, ten different populations of Aloe vera collected from various geographical locations of Karachi,Pakistan were studied by aceto-orcein staining technique. The results showed that chromosome number of Aloe vera is2n=14. The karyotype is bimodal and consists of 14 chromosomes (8 large and 6 small) predominantly with submedian,median and subterminal centromere. Average chromosome lengths among populations ranged from 7.95-2.36 μm.
