Use of defense mechanisms to quantify resistance of wheat genotypes to drought

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.
Biography
Bousba Ratiba has received her degree in 2012 in plant physiology and biochemistry from Constantine University. She is life member of network durum wheat
research and her current research interests include: abiotic stress, molecular marker, plant physiology and plant biotechnology. Presently she is assistant professor
at Constantine University and published six papers. She is reviewer in many journals of plant crop research, genetics and physiology. She has done many handouts
on mycorhyses, symbiosis and QTL cartography and genetic association phenotype genotype in durum wheat.
