摘要: Different techniques are being employed to reduce the adverse effects of water stress on seed yield and quality crop plants. The current study aimed improve tolerance field-grown sunflower by foliar-supplied ecofriendly iron-chelated aspartate (Fe-Asp) in comparison with FeSO4. Water decreased plant growth yield, accompanied disturbed relations, nutrient acquisition, accumulation amino acids, antioxidative defense mechanisms. However, lipid peroxidation, total anthocyanin, photosynthetic pigments were increased. Fertigation FeSO4 Fe-Asp as foliar sprays proved effective negativities limited irrigation biomass production a reduction peroxidation improvements mechanisms, leaf pigments. In FeSO4, foliary applied better improved relations more essential acids especially (Asp) Fe which showed translocation. Overall, for induction drought plants compared recommended use spray under irrigation.
