Abstract

This research was carried out under greenhouse conditions to examine the Cd accumulation in the organs of some sorghum varieties at the end of cadmium treatment (0, 25, 50, 75, 100, and 125 mg kg⁻¹). At the end of a 130-day growing period, the Cd concentrations accumulated in the roots, stems, leaves, and grains of the plants were examined. In the 3 cultivars used in the study, the highest Cd concentration was found in the root of the plants. Unlike Akdari variety, higher cadmium concentrations were detected in the leaves of Beydari and Ogretmenoglu than their stems. While the Cd concentration in the grains of Akdari variety was 4.97 mg kg⁻¹, it was measured as 0.17 mg kg⁻¹ in Beydari and 0.78 mg kg⁻¹ in Ogretmenoglu. The grain/root translocation factor (TF) was determined as 0.48 in Akdari, 0.01 in Beydari, and 0.15 in Ogretmenoglu. It was found that Akdari variety carried more Cd to its grains; so, this variety is not suitable as it poses a risk in human and animal nutrition. On the other hand the Beydari variety was found to transfer the least Cd, which makes it more suitable. Since Ogretmenoglu removed more Cd from the soil than other varieties, it is promising in terms of phytoremediation.

摘要

本研究是在温室条件下进行的，目的是检测在镉处理（0、25、50、75、100 和 125 mg kg ^-1）结束时某些高粱品种器官中 Cd 的积累。在 130 天的生长期结束时，检测了植物根、茎、叶和谷物中积累的 Cd 浓度。在研究中使用的 3 个栽培品种中，在植物根部发现了最高的 Cd 浓度。与 Akdari 品种不同，Beydari 和 Ogretmenoglu 的叶子中检测到的镉浓度高于其茎。Akdari 品种谷物中的 Cd 浓度为 4.97 mg kg ^-1，在 Beydari 中测量为 0.17 mg kg ^-1和 0.78 mg kg ^-1在 Ogretmenoglu。谷物/根易位因子 (TF) 在 Akdari 中确定为 0.48，在 Beydari 中为 0.01，在 Ogretmenoglu 中为 0.15。发现 Akdari 品种携带更多的 Cd 到其谷物中；因此，该品种不适合，因为它对人类和动物营养构成风险。另一方面，发现 Beydari 品种转移的 Cd 最少，这使其更适合。由于 Ogretmenoglu 从土壤中去除的 Cd 比其他品种多，因此在植物修复方面很有希望。
