摘　　要：本试验以不同浓度盐胁迫和不同浓度钙缓解盐胁迫对金鸡菊幼苗进行处理,通过测量叶片的脯氨酸含量,质膜相对透性和丙二醛等部分生理指标的变化,研究金鸡菊对不同盐环境的耐受能力。结果表明,随NaCl浓度的增大,植物的丙二醛含量和脯氨酸含量总体上升,质膜相对透性都呈现不同程度的减弱。而用不同浓度的CaCl_(2)能够缓解盐对金鸡菊生长的影响,CaCl_(2)在一定范围内,浓度越大,对NaCl胁迫的缓解效果越好。The experiment involved different concentrations of salt stress and different concentrations of calcium to alleviate salt stress in Coreopsis grandiflora,in order to study the tolerance of Coreopsis grandiflora to different salt environments.Physiological and biochemical indexes,including chlorophyll content,proline content,root vigor variation,plasma membrane relative permeability,and malondialdehyde(MDA),were measured.The results show that with the increase of NaCl concentration,the content of malondialdehyde(MDA)and proline overall rises;however,root vigor,chlorophyll content,and plasma membrane relative permeability show varying degrees of decrease.Different concentrations of CaCl can alleviate the influence of salt stress on Coreopsis grandiflora.Within a certain range,the higher the concentration of CaCl,the better the relief from NaCl stress.
