Abstract

To investigate cytogenetics of ALOE LITORALIS and ALOE VERA, samples were taken during flowering stage from several local populations of the species in the southern parts of IRAN, such as Bushehr and Hormozgan provinces. The samples were fixed at the sites and studied at the Forests and Rangelands Research Institute. CHROMOSOME BEHAVIORs in miosis cell division were studied in the populations and a number of parameters such as number and type of formed chiasmas were recorded. One hundred cells per population were studied for the purposes. Despite the big size of the chromosomes of the species, the most portion of the observed chiasmas were one chiasma per pairs of homologes. Two chiasmas per homologes were in the next level. Four chiasma were hardly observed, but a population of A.litoralis showed a high level of the phenomenon, so that on the whole, the population presented the higher number of chiasma. Since chiasma formation and miotic behaviors is believed to be genetically controled, these can be due to genomic diffrentiation between the populations in the locations. One or two lag chromosomes were observed in several populations. Late separation of the chromosomes at anaphase II was also observed for all of the populations. Presence of these phenomena at different stages of the mitotic cell division may imply an active trend of evolution in the studied populations.
