Title Of Article :
A Preliminary Study on Chromium(VI) Tolerance at Early Seedling Stage of Some Barley Cultivars Grown in Turkey
Abstract :
In this research, hexavalent chromium [Cr(VI)] tolerance of eight barley (Hordeum vulgare L.) cultivars grown in Turkey was investigated at early seedling stage in hydroponic culture. The effect of different Cr(VI) concentrations (0, 75, 150 and 225 μM) on shoot and root growth of eight barley cultivars (Angora, Avcı-2002, Aydanhanım, Başgül, Bülbül-89, Orza-96, Tarm-92 and Zeynelağa) was determined. In general, the lengths, fresh and dry weights of shoots and roots of barley cultivars were significantly decreased with an increase in Cr(VI) concentrations (P 0.05). Cr(VI) tolerance index (%) determined as a result of dry weights was evaluated as the most reliable criterion. The most Cr-tolerant barley cultivar, Zeynelağa, and the most Cr-sensitive barley cultivar, Orza-96, were determined according to Cr(VI) tolerance index.
