以滁菊扦插苗为材料，采用不同盐浓度进行盆栽实验，研究了在不同 NaCl 浓度(0、100、200、300、400、500 mmol·L-1)下，滁菊的形态及叶绿素含量、可溶性糖含量、脯氨酸含量、MDA 含量、叶片伤害率和根系活力等生理指标的变化情况。结果表明：叶绿素含量、根系活力随盐胁迫强度的增强而下降；可溶性糖和MDA 含量随盐胁迫强度的增强呈先升后降趋势；叶片伤害率、脯氨酸含量随盐胁迫强度的增强而增加。研究发现滁菊扦插苗能耐受较低浓度的盐胁迫，当盐浓度较高时，其生长受到较大抑制。

Cutted seedlings of Chrysanthemum morifolium cv.Chuju were treated with different concentrations of NaCl (0,100,200,300,40,500 mmol·L-1 )to probe the effects of salt stress.Morphological characteristics,root ac-tivity and contents of stress related components (such as chlorophyll,soluble sugar,proline,and MDA)were meas-ured.The results indicated that with the increase of salinity ,the chlorophyll content and root activity decreased grad-ually,and the contents of soluble sugar and MDA decreased after an initial increase,while the relative electrolytic leakage and proline content increased continuously.The above results suggested that the cutting seedlings of C . morifolium cv.Chuju could tolerate lower concentration NaCl stress,but under higher concentration of NaCl,its growth would be inhibited obviously.
