摘　　要：为明确盐碱土壤对菊芋(Helianthus tuberosus)中菊糖含量的影响,利用高效液相色谱法对农田土壤与盐碱土壤上生长的7个品系菊芋的菊糖含量进行分析,盐碱土壤包括轻度盐碱土壤与重度盐碱土壤。结果表明:生长于盐碱土壤的菊芋的菊糖含量均低于农田土壤,其中菊芋品系2、品系5和品系7在轻度盐碱土壤中生长时菊糖含量高于重度盐碱土壤;菊芋品系1、品系4和品系6在重度盐碱土壤中生长时菊糖含量高于轻度盐碱土壤。7个品系中,品系4的菊糖含量在盐碱土壤下降低最多,品系6的菊糖含量在盐碱土壤下降低最少,但其含量在三种生长条件下是所有品系中最低的;品系5的菊糖含量虽然在盐碱土壤下也有所降低,但其含量在三种生长条件下都是所有品系中最高的,推测品系5比较适合在盐碱土壤上生长,在改良盐碱地时可优先选用。To clarify the effects of saline soils on inulin content in Jerusalem artichokes,we analyze the inulin content of seven strains of Jerusalem artichokes grown on farmland and saline soils,which in-clude mild saline soils and severe saline soils by HPLC.The results show that the inulin content in Je-rusalem artichokes grown on the saline soils is lower than that on the farmland.It is also found that the inulin content in Jerusalem artichokes strain 2,strain 5,and strain 7 grown on the mild saline soils is higher than that on the severe saline soils and the inulin content in Jerusalem artichokes strain 1,strain 4,strain 6 grown on the severe saline soils is higher than that on the mild saline soil.The in-ulin content of strain 4 declines the most on the saline soils in the seven strains.The inulin content of strain 6 declines the least on the saline soils,but its inulin content is the lowest in the seven strains under the three growing conditions.Although the inulin content of strain 5 also declines on the saline soils,but its inulin content is the highest in the seven strains under the three growing conditions;it is supposed that strain 5 is suitable for growing on the saline soils possibly and it can be preferred to im-prove the saline soils.
