Abstract
Toxic effects of the wastewater were investigated ultrastructurally in root tips of Triticum aestivum. As a result, wall and nuclear degradations, disruptions in all cytoplasmic membranes, irregular nucleus shapes and cellular organization defects were densely detected. Besides, germination ratio, total protein contents, DNA contents and root-shoot growth were found to be decreased significantly when compared to the control group. Results were compared with those of recent studies regarding excessive Na+, Fe+2, P, polyphenols and acidic pH toxicity. © 2008 Asian Network for Scientific Information.
