...Therefore, present investigations were aimed (i) to elucidate key mechanisms involved in drought tolerance by comparing selected A. tricolor cultivars, differing in their extent of drought tolerance; (ii) to identify tolerant cultivars to drought stress; and (iii) to explore the relationships among physiological, ROS markers, compatible solutes, and non-enzymatic antioxidant to obtain more tolerant cultivars under drought stress....
