摘　　要：麻风树是重要的生物柴油树种。为了评估种植麻风树的潜在生态风险,应用蚕豆根尖微核技术,研究了麻风树叶水浸提液的遗传毒性。结果表明:麻风树叶水浸提液诱导了染色体畸变,导致畸变率和微核率显著高于对照;较低浓度的麻风树叶水浸提液促进蚕豆根尖细胞有丝分裂,进而促进根的生长,而较高浓度的叶水浸提液抑制根尖细胞的有丝分裂和根的生长。Genetic toxicity of a biofuel crop, Jatropha curcas was evaluated by using Vicia faba root tip micronucleus assays. The results showed that the chromosome aberration of Viciafaba root tip cells was induced by the aqueous leaf extracts of J. curcas, and aberration rates and micronucleus rates were significantly higher than those of control groups. The lower concentration aqueous leaf extract could promote mi- tosis of root tip cells and root growth of V. faba, and the higher concentrations aqueous leaf extract exhibited the opposite effects.
