Abstract

Survival and productivity of crop plants exposed to environmental stresses are dependent on their ability to develop adaptive mechanisms to avoid tolerate stress. This study was following to find characters of resistant under drought stress, it was carried out to study the influence of water deficit in the leaves and roots of durum wheat plants were grown in hydroponic medium and were subjected to different water treatment. At the third leaf emergence stage two genotypes are compared with each other for their tolerance and their biochemical and physiological responses to water deficit. The following parameters are measured superoxide dismutase SOD: Activity, malondialdehyde MDA content, hydrogen peroxide H2O2 level, the content of anthocyanins and chlorophyll. These parameters made difference between genotypes. Thus, this attributes can be used as screening tool for drought tolerance in wheat. They lend full support to results presented by researchers showing that wheat lines can differ consistently for their defensive mechanism. These results also emphasize the important role of secondary metabolites that are anthocyanin in the defense against oxidative stress caused by abiotic stress in the detoxification of reactive oxygen species (ROS) under stress conditions.
