Rosea) an experiment was implemented in a randomized complete blocks design with four concentrations of colchicine (0, 0.1, 0.2 and 0.4%) Spraying was carried out in six replicates in the two true leaf stages. The results of the analysis by using flow cytometry, cytogenetic and morphological indicated that treatments of 0.2 and 0.4% had significant effect (p CP - IRAN IN - Chehrazi_m@yahoo.com LG - eng PB - jispp PG - 1 PT - Applicable YR - 2015
