摘要: 为研究不同豇豆材料对重金属镉的吸收积累差异,以12份豇豆材料作为研究对象,于镉污染的土壤进行盆栽试验。结果表明,在镉胁迫下,幼苗期的豇豆材料HF1013-25-2-1-1地上部生物量显著高于其他豇豆材料,镉含量也较高,7104地上部分生物量最低,镉含量最高,其他豇豆材料地上部分生物量处于HF1013-25-2-1-1与7104之间。就成株豇豆而言,豆荚生物量较高的前4个豇豆材料按生物量高低的顺序分别是:FA黑黑-3-1-青荚>15279>17300>HF1013-25-2-1-1,豆荚生物量最低的豇豆材料为15282-1,其他材料的生物量处于FA黑黑-3-1-青荚和15282-1之间。7104的豆荚镉含量最低,除7104外,其余11份豇豆材料之间的豆荚镉含量差异不显著。因此,在镉污染区域,可优先选择豆荚生物量高且镉含量低的FA黑黑-3-1-青荚、15279材料进行种植。

Abstract: In order to study the differences of absorption and accumulation characteristics of heavy metal cadmium(Cd) in different cowpea materials,a preliminary pot experiment was conducted using 12 cowpea materials in Cd contaminated soil.The results showed that, under Cd stress, the biomass of cowpea HF1013-25-2-1-1 in seedling stage was significantly higher than that of other cowpea materials,and its Cd content was also higher.For 7104 in seedling stage,the biomass above ground was the lowest and Cd content was the highest,and the biomass above ground of other cowpea materials was between HF1013-25-2-1-1 and 7104.When cowpeas matured,the first four cowpea materials with high pod biomass were:FA black-black-3-1-green pod>15279>17300>HF1013-25-2-1-1,while the pod biomass of 15282-1 was significantly lower than that of other cowpea materials,and other materials were between FA black-black-3-1-green pod and 15282-1.Cowpea 7104 had the lowest Cd content in pods,and except 7104,there was no significant difference in Cd content of pods among 11 other cowpea materials.Therefore,cowpea FA black-black-3-1-green pod and 15279 with high pod biomass and low Cd content can be given preference to plant in the Cd-polluted areas.
