To explore effects of NaCl stress on leaf morphological structures of Manilkara roxburghiana and M. zapota, paraffin section, light microscopy and scanning electron microscopy were adopted. The results indicated that the characteristics of epidermis and tissue structures were related to the NaCl concentration. When NaCl concentration rising, the cuticle creased, the stoma was widely opened, the stomatal apparatus turned abnormal, the palisade tissues loosened, the spongy tissues and vascular bundles were distorted. The phloem was distorted earlier than xylem. The leaf tissue structure kept normal under low NaCl concentration (0, 0.2%, 0.4%) while observed abnormal under high NaCl concentration (0.6%, 0.8%), showing the changes of tissue structure later than those of epidermis.
