Evaluation of chlorophyll content and membrane stability under oxidative stress induced by glyphosate herbicide as indicators of drought tolerance in some advanced durum wheat (Triticum durum L.) lines: in vitro study

Oxidative stress caused by glyphosate is a complex chemical and physiological phenomenon develops as result of overproduction accumulation reactive oxygen species (ROS). This study was carried out in vitro at the National Institute Agronomic Research Algeria (INRAA) Setif, to select most susceptible durum wheat (Triticum L.) under oxidative induced herbicide evaluating chlorophyll content degradation cell membrane leakage. Genotypes showed significant variations almost all studied traits. The loss ratio ranged from 26.42 % for genotype G5 48.75 local variety Boutaleb, sensitivity index values were found be between 0.65-1.2, advanced line tolerant with lowest Glyphosate index. Furthermore, G4 recorded highest electrolyte leakage (80.16 %) while G6 estimate (50.77 %). Therefore, lines appear suitable growing conditions.
