title: Evaluation of germination, root growth and cytological effects of wastewater of sugar factory (Afyonkarahisar) using Hordeum vulgare bioassays.
abstract: In this study, the effect of Afyonkarahisar Sugar Factory's discharge water on germination percentage, root growth and mitotic divisions of the root tip cells of Hordeum vulgare L. were investigated. Six concentrations of wastewater and ranging from 10(0), 10( -1), 10( -2), 10( -3), 10( -4), 10( -5), were applied for 6, 12, 18 and 24 h, respectively. It was observed that the treatments reduced the germination percentages of H. vulgare grains and inhibited the root growth as well as reduced mitotic index compared to the control group at all concentrations. It was also observed that the increase of the concentrations of wastewater decreased the cell division, and several mitotic anomalies such as c-mitosis, lagging chromosomes, multipolar anaphases and chromosome bridges increased.
