Abstract
Recently boron is a hot topic for it is an energy source and it is widely used in industry. It is said to be the “energy of the future”. Turkey is an important boron deposit in the world besides being an agriculture country where boron deposits are mainly located in agriculture regions. In this respect, to determine the tolerant species for toxic levels of boron is quite important. In this study, toxic effects of boron were investigated on two species of wheat, Triticum aestivum and Triticum durum by using three genotypes from each. My research question was “What are the toxic effects of boron on the growth of roots, shoots, leaves of Triticum aestivum and Triticum durum genotypes?” It was hypothesized that as T. aestivum and T.durum are grown in soil containing toxic dosage of boron, they will show the signs of toxication. In order to test the hypothesis and to answer the research question three replications were performed from both test groups (to which boron was applied at toxic level-20 ppm) and control groups (boron negative) of each genotype and the results were evaluated by using two parameters: 1) Root and shoot growth inhibition 2) 1-5 scale for evaluation of the color changes on the leaves. At the end of the experiment, it is seen that the toxic effect of boron on both species of wheat is significant whereas durum wheat is much more sensible. Also genetic variation exists in response to boron toxicity in different genotypes of the same species. Statistical analysis also proved significant difference between the species and genotypes of the same species. It is concluded that tolerant and sensible genotypes can be determined and tolerant species can be used in agriculture.
