Abstract:
      Peanut seeds treated with different NaCl concentrations (0, 100, 200, 300, 400 and 500 mmol/L) were studied with peanut cultivar Luhua 14 (LH14) and Fenghua 1 (FH1). The main results were described as follows. The effect of low concentration of NaCl treatment (100 mmol/L) on peanut seed germination was relatively small. With the increase of NaCl concentration, peanut seed gemmination energy and germination rate decreased gradually, the same as root length, root surface area, root volume,root fresh weight and radicle diameter. But MDA and proline content in-creased gradually. DNA gel electrophoresis in the peanut root tip with high concentration of NaCl had obvious continuous band, 80 the apoptosis of root tip cells was relatively serious.
