Evaluation the Response of Some Wheat Genotypes at Seedling Stage to Water Stress


Abstract in English

This study was carried out at the Faculty of Agriculture, Damascus University, and ACSAD during the year 2001 – 2002 in order to assess the genetic variability of twenty wheat genotypes for osmotic stress tolerance by using PEG-6000 as a water stress induced tool. This trial aimed to develop a semi-natural rapid and effective screening technique in which the optimum induction as well as lethal levels of osmotic stress are well defined . The results revealed that the treatments –0.4 MPa and –1.5 MPa were the optimum induction and lethal levels of osmotic stress, respectively.
