We propose to identify the influence of organic acids as well as total proteins in the accumulation and translocation of heavy metals from the rhizosphere to the plant organs of cultivated yellow melon var. Natal throughout the vegetative cycle. Physical and chemical attributes and the concentration of Cu, Zn, and Pb were determined in soil samples. Samples of plant tissue and rhizosphere at 0, 15, 30, 45, and 60 days after transplantation were collected and determined the concentration of heavy metals along with the content of total protein in the tissues and organic acids in the rhizosphere. Subsequently, the transfer factor (TF) and bioconcentration factor (BF) were calculated. Oxalic and citric acids and heavy metal contents were slightly higher in the rhizosphere than those found in the soil. The organic acids and total protein showed correlations with the concentration of heavy metals in different organs of the plant. The protein content in the plant tissues and the contents of oxalic and citric acid released by the plant in the rhizosphere can increase or decrease the absorption, accumulation, and translocation of Cu, Zn, and Pb in the different organs of the yellow melon var. Natal. Even the BF and TF showed values higher than one, being indicative of phytoextraction potential in several stages of the vegetative cycle for Cu and Zn, the yellow melon var. Natal cannot be considered as a hyperaccumulator plant for not meeting all necessary criteria for that purpose.

我们建议确定有机酸以及总蛋白对重金属从根际到栽培黄瓜变种植物器官的积累和转运的影响。在整个营养周期中都保持纳塔尔状态。测定土壤样品中的理化特性以及铜，锌和铅的浓度。收集移植后0、15、30、45和60天的植物组织和根际样品，测定组织中重金属的浓度以及组织中总蛋白的含量，并确定根际中有机酸的含量。随后，计算转移因子（TF）和生物浓缩因子（BF）。根际中的草酸，柠檬酸和重金属含量比土壤中的略高。有机酸和总蛋白与植物不同器官中的重金属浓度相关。植物组织中的蛋白质含量以及植物在根际中释放的草酸和柠檬酸含量可以增加或减少黄色甜瓜变种不同器官中Cu，Zn和Pb的吸收，积累和转运。纳塔尔 甚至BF和TF都显示出高于1的值，这表明在营养循环的多个阶段中，黄色和黄色瓜类Cu和Zn的植物提取潜力。纳塔尔不能满足该目的所有必要标准，因此不能被视为过度蓄积植物。植物组织中的蛋白质含量以及植物在根际中释放的草酸和柠檬酸含量可以增加或减少黄色甜瓜变种不同器官中Cu，Zn和Pb的吸收，积累和转运。纳塔尔 甚至BF和TF都显示出高于1的值，这表明在营养循环的多个阶段中，黄色和黄色瓜类Cu和Zn的植物提取潜力。纳塔尔不能满足该目的所有必要标准，因此不能被视为过度蓄积植物。植物组织中的蛋白质含量以及植物在根际中释放的草酸和柠檬酸含量可以增加或减少黄色甜瓜变种不同器官中Cu，Zn和Pb的吸收，积累和转运。纳塔尔 甚至BF和TF都显示出高于1的值，这表明在营养循环的多个阶段中，黄色和黄色瓜类Cu和Zn的植物提取潜力。纳塔尔不能满足该目的所有必要标准，因此不能被视为过度蓄积植物。黄瓜变种在铜和锌的营养循环的几个阶段中都具有植物提取潜力。纳塔尔不能满足该目的所有必要标准，因此不能被视为过度蓄积植物。黄瓜变种在铜和锌的营养循环的几个阶段中都具有植物提取潜力。纳塔尔不能满足该目的所有必要标准，因此不能被视为过度蓄积植物。
