摘  要:
[目的]研究紫叶李对重金属镉和铅胁迫的生理响应。[方法]研究不同浓度镉(10、30、50、100、150、200 mg/kg)、铅(50、100、500、1 000、1 500、2 000 mg/kg)对紫叶李的相对电导率、丙二醛和叶绿素含量的影响。[结果]随着镉浓度和铅浓度的升高,紫叶李的相对电导率和丙二醛含量总体呈升高趋势,叶绿素含量明显降低,在铅浓度2 000 mg/kg和镉浓度200 mg/kg时,叶绿素含量分别较对照降低60.9%和50.1%。[结论]紫叶李是一种抗重金属能力较强的植物。

摘  要:
[Objective] The aim was to study physiological response of Prunus cerasifera to cadmium,lead stress. [Method]Effects of different concentrations of cadmium( 10,30,50,100,150,200 mg/kg) and lead( 50,100,500,1 000,1 500,2 000 mg/kg) on relative electrical conductivity,MDA content and chlorophyll content were studied. [Result] With the increase of cadmium concentration and lead concentration,the relative electrical conductivity and MDA content showed an increasing trend,chlorophyll content decreased significantly. When lead concentration was 2 000 mg/kg and cadmium was 200 mg/kg,the chlorophyll content was decreased by 60. 9% and 50. 1% respectively compared with control. [Conclusion] Prunus cerasifera is a kind of heavy metal resistant plant.
