| 摘 要： | 利用植物修复技术对土壤重金属污染进行治理是国内外学者研究的热点和难点问题。综述了国内外草坪植物修复重金属铅污染的现状、吸收机理、草坪草体内运输、累积和分布及其草坪草对铅的耐性机制的研究进展。铅对草坪生理伤害主要从细胞分裂、超微结构、细胞膜透性、光合作用和抗氧化酶系统等生理生化方面讨论了铅对植物的伤害机理,其次,分析了根系pH、根系分泌物、金属配位体等与植物耐性机制的关系。并提出了今后进行草坪草铅修复研究的发展趋势和建议。

| Abstract: | Phytoremediation,a technology using plants to remove contaminants from soil,has become a hot topic in the current research.The mechanisms of heavy metal absorbing,transportation,accumulation,distribution and tolerance in turfgrasses were reviewed.The damaging mechanism of lead was discussed in terms of physiological and biochemical aspects.The relationships between the tolerance and root system and metal cheaters were analyzed.The suggestions for further research were provided as well. |
