AB  - BACKGROUND: The epicuticular waxy layer of plant leaves enhances the extreme 
      environmental stress tolerance. However, the relationship between waxy layer and 
      saline tolerance was not established well. The epicuticular waxy layer of rice 
      (Oryza sativa L.) was studied under the NaHCO3 stresses. In addition, strong 
      saline tolerance Puccinellia tenuiflora was chosen for comparative studies. 
      RESULTS: Scanning electron microscope (SEM) images showed that there were 
      significant changes in waxy morphologies of the rice epicuticular surfaces, while 
      no remarkable changes in those of P. tenuiflora epicuticular surfaces. The 
      NaHCO3-induced morphological changes of the rice epicuticular surfaces appeared 
      as enlarged silica cells, swollen corns-shapes and leaked salt columns under high 
      stress. Energy dispersive X-ray (EDX) spectroscopic profiles supported that the 
      changes were caused by significant increment and localization of [Na(+)] and 
      [Cl(-)] in the shoot. Atomic absorption spectra showed that 
      [Na(+)]shoot/[Na(+)]root for P. tenuiflora maintained stable as the saline stress 
      increased, but that for rice increased significantly. CONCLUSION: In rice, NaHCO3 
      stress induced localization and accumulation of [Na(+)] and [Cl(-)] appeared as 
      the enlarged silica cells (MSC), the swollen corns (S-C), and the leaked columns 
      (C), while no significant changes in P. tenuiflora.
