Abstract:
      In this study, 16 maize inbred lines were employed to determine growth parameters at germination and seedling stage under stress. The results indicated that germination potential, germination rate, root length, shoot length, root fresh weight, shoot fresh weight decreased at germination stage, and the relative conductivity, malondialdehyde(MDA) increased, but relative water content decreased at seedling stage in different maize inbred lines under 180 mmol·L-1 NaCl stress. Finally, we screened high salt-tolerant inbred line 87-1,8723 and 78599-1, medium salt-tolerant lines LX9801, TS141, A413,137 and 81162, salt-tolerant inbred lines Langhuang, Chang7-2,478 and Cheng687, salt-sensitive inbred line 9046 and 65232, and high salt-sensitive inbred line 543 and 136.
