摘要
Four plants (corn, pumpkin, sunflower %26 water morning glory) were tested for their ability to germinate and grow in an alkaline Thai soil contaminated with 0.2-20 mg/kg dry soil of either lindane or alpha-endosulfan, two organochlorine pesticides commonly found in agricultural soils in Thailand. Based on root length assessment, sunflower was the most tolerant to lindane contaminant, while corn was the most tolerant to alpha-endosulfan in the alkaline soil. Base on root dry weight assessment, corn was the most tolerant to both lindane and alpha-endosulfan. Corn was selected to further test its ability to tolerate a mixture of 0.2, 2.0, 20 mg/kg dry soil of lindane and alpha-endosulfan in the alkaline soil. The presence of both pesticides decreased root length of corn but did not affect its shoot and root dry weights. The results suggest that corn is suitable for use in the phytoremediation of alkaline soil contaminated with a mixture of lindane and alpha-endosulfan.
