　　为了探讨盐胁迫对松果菊生长及其药用成分菊苣酸含量的影响，分别以0、30、60、90、120、150 mmol/L的NaCl处理土培的松果菊植株，并测定处理后的松果菊盐害指数、鲜重、干重以及菊苣酸含量。结果表明：盐害指数随着盐浓度的升高而升高；120 mmol/L及以下浓度的NaCl处理对松果菊鲜重影响并不明显，而150 mmol/L时则使鲜重显著降低；随着盐浓度的升高，松果菊干重呈逐渐减小的趋势；菊苣酸含量随盐浓度的升高呈先升高后下降的趋势，在90 mmol/L时达到最大值；菊苣酸的单株产量在盐浓度为0~60 mmol/L时无显著变化，在90 mmol/L时显著升高，之后显著降低。盐胁迫虽然对松果菊生长产生了一定的盐害作用，但在一定的盐浓度范围内(0~90 mmol/L)也同时提高了菊苣酸的含量水平。

To study the effects of NaCl on the growth and cichoric acid content of Echinacea purpurea, 0, 30, 60, 90, 120 and 150 mmol/L NaCl were treated to E. purpurea cultivated in garden soil, and salt injury index, fresh weight, dry weight and cichoric acid content were determined. The results showed that: with the increase of NaCl concentration, salt injury index increased as well; less than or equal to 120 mmol/L NaCl did not bring obvious influence to the fresh weight of E. purpurea, while 150 mmol/L NaCl markedly decreased their fresh weight; the dry weight of E. purpurea reduced gradually as salt concentration rose; cichoric acid content increased first and then decreased with the increase of salt concentration, getting to the maximum value at 90 mmol/L NaCl level; cichoric acid production per plant showed no significant change between 0 and 60 mmol/L NaCl, increased significantly at 90 mmol/L and then decreased obviously. Although salt stress caused a certain degree of salt damage to E. purpurea, it increased cichoric acid content within a certain salt concentration (0-90 mmol/L).
