    Structural changes in root tips of wheat (Triticum aestivum L.) in response to olive oil mill wastewater
    (2008) Aybeke M.; Sidal U.; Hüseyin G.
    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.

    Effects of olive oil mill wastewater used as irrigation water on in vitro pollen germination
    (2011) Aybeke M.; Sidal U.
    The aim of this study is to assess the effects of Olive Oil Mill Wastewater (OOMW) application as irrigation water on in vitro pollen germination, focusing on total protein quantity. In test groups, pollen germination substances such as sucrose, H 3BO 3 and Ca(NO 3) 2 were added to different concentrations of OOMW and used as germination media. Regarding control group, the same substance melted into water instead of OOMW. As a result, in general, pollen germination percentage was decreased significantly in all OOMW concentrations than that of the control group, except 1/1000 concentrations. Similarly, total protein quantities declined linearly depending on decreasing OOMW concentrations, except 1/1 concentration which has 4-5 times the control value. Consequently, it was established that OOMW generally decreased pollen germination ratio and had carcinogenic effects on protein synthesis mechanism and must not be used as irrigation water without purification. © 2011 Asian Network for Scientific Information.
