Cadmium is a widely distributed heavy metal in agricultural soils that affects plant growth and productivity. In this context, the current study investigated the effects of different cadmium (Cd) doses (0, 25, 50, 75, and 100 mg L of CdSO) on the growth and physiological attributes of safflower ( L.) including plant height (cm), root length (cm), fresh weight (g) of root, stem, and leaves, leaf number, macro and micro-nutrients, Se, and heavy metal (Cd, Cr, and Pb) content. The experiment was carried out in a completely randomized design (CRD) with four replicates. The results showed that Cd stress significantly negatively affected all growth indices, macro- and micro-nutrients, and heavy metal content. In addition, it increased the MDA and APX activities. The highest amounts of Fe, Mn, Ni, Pb, Zn, K, Na, Cd, Cr, and Cu were determined in plant roots, while the highest values of Ca and Mg were detected in plant stem tissues. High Cd doses decreased the content of Ca, K, Mg, Cr, Cu, Fe, Mn, Ni, Pb, Se, and Zn in safflower plant tissues by 45.47%, 39.33%, 79.28%, 68.21%, 37.06%, 66.67%, 45.62%, 50.38%, 54.37%, 33.33% and 65.87%, respectively, as compared to the control treatments.
镉是农业土壤中广泛分布的重金属，会影响植物生长和生产力。在此背景下，本研究调查了不同镉（Cd）剂量（0、25、50、75和100 mg/L硫酸镉）对红花（ ）生长和生理特性的影响，包括株高（cm）、根长（cm）、根、茎和叶的鲜重（g）、叶片数量、大量和微量营养素、硒以及重金属（Cd、Cr和Pb）含量。实验采用完全随机设计（CRD），重复四次。结果表明，镉胁迫对所有生长指标、大量和微量营养素以及重金属含量均有显著负面影响。此外，它还增加了丙二醛（MDA）和抗坏血酸过氧化物酶（APX）的活性。植物根系中Fe、Mn、Ni、Pb、Zn、K、Na、Cd、Cr和Cu的含量最高，而植物茎组织中Ca和Mg的含量最高。与对照处理相比，高镉剂量使红花植物组织中Ca、K、Mg、Cr、Cu、Fe、Mn、Ni、Pb、Se和Zn的含量分别降低了45.47%、39.33%、79.28%、68.21%、37.06%、66.67%、45.62%、50.38%、54.37%、33.33%和65.87%。
