In control experiments, distilled water was used instead of fungicides. Effects of Korsikol and Derosal on structure and behaviour of chromosomes were investigated using mitosis analysis on root tip cells of barley seeds which were germinated after the chemical application. In addition, modifying effects of these two fungicides on mitotic index were studied. Cytological findings which were obtained from these experiments showed that the fungicides affect cell division and chromosome structure depending on dose which were used in time intervals.]]>Aokin, T. and O.
