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 }, URL = {http://jispp.iut.ac.ir/article-1-191-en.html}, eprint = {http://jispp.iut.ac.ir/article-1-191-en.pdf}, journal = {Plant Process and Function}, doi = {}, year = {2015} }
