The goal of this research was to determine whether or not chickpea (Cicer arietinum L.), commonly known as Garbanzo beans, is a hyper accumulator for copper (Cu) in contaminated soils amended with EDTA. Statistical analysis (2 tailed Pearson Correlation) revealed significant correlations between: Translocation index and stem biomass (r = 0.859**; p < 0.01); Tolerance index and stem biomass (r = 0.762**; p < 0.01); and bioconcentration factor of stem/soil and soil Cu concentration (r = -0.545*; p < 0.05). Therefore, C. arietinum seems to be a cost-effective and environmentally friendly hyperaccumulator for Cu at 100 ppm Cu and 10 mM EDTA.
本研究旨在确定鹰嘴豆（Cicer arietinum L.）是否为受 EDTA 改良污染土壤中铜（Cu）的超富集植物。统计分析（双尾 Pearson 相关性）显示：转运指数与茎生物量之间呈显著正相关（r = 0.859**；p < 0.01）；耐受指数与茎生物量之间呈显著正相关（r = 0.762**；p < 0.01）；茎/土壤比的生物浓缩系数与土壤 Cu 浓度之间呈显著负相关（r = -0.545*；p < 0.05）。因此，在 100 ppm Cu 和 10 mM EDTA 条件下，鹰嘴豆似乎是一种经济高效且环境友好的 Cu 超富集植物。
