The survival, biomass production and copper (Cu) remediation efficiency of Jatropha curcas L. was evaluated in Cu rich industrial wasteland soil (IWLS), collected from a local town, Sandila (Hardoi), Uttar Pradesh, India. The IWLS had high bulk density, water holding capacity (WHC), pH, electrical conductivity (EC), organic carbon and NPK. The Cu and Mn contents in IWLS were about 3 and 2 fold higher than that in the normal field soil (control). Stem cuttings of the J. curcas clones (BTP-A, BTP-N and BTP-K) were planted in IWLS as well as the same amended with cowdung or sand. The percent survival, net elongations and biomass accumulation of J. curcas were decreased slightly in IWLS, as compared to the control soil. The translocation of Cu from soil to the plants was higher in IWLS grown plants, which was more pronounced in IWLS amended with cowdung. J. curcas clones BTP-N, showed better survival and Cu removal efficiency from IWLS.
对麻风树在富含铜的工业废弃地土壤（IWLS）中的存活情况、生物量生产及铜修复效率进行了评估，该土壤采自印度北方邦桑迪拉（哈多伊）的一个当地城镇。IWLS具有高容重、持水量（WHC）、pH值、电导率（EC）、有机碳及氮磷钾。IWLS中的铜和锰含量比正常田间土壤（对照）高约3倍和2倍。将麻风树克隆品种（BTP - A、BTP - N和BTP - K）的茎插条种植于IWLS以及添加了牛粪或沙子的相同土壤中。与对照土壤相比，麻风树在IWLS中的存活百分比、净伸长和生物量积累略有下降。在IWLS中生长的植株，铜从土壤向植物的转运更高，在添加了牛粪的IWLS中更为明显。麻风树克隆品种BTP - N在IWLS中表现出更好的存活及铜去除效率。
