The Comparative Anatomy on Leaves of 4 Halophytes of Chenopodiaceae in Salt Lake of Yuncheng

The comparative anatomy on the leaves of 4 halophytes of Chenopodiaceae in salinate fields of salt lake in Shanxi Yuncheng were carried out by scanning electron microscope and light microscope.The results indicated that Suaeda glauca and Suaeda salsa belonged to Euhalophyte,and they had the same anatomical structure to adapt to the salt conditions:the leaves were line-shaped and fleshy,and the stomata were dense.There were well-developed water-storing tissues and flourishing palisade tissues in their leaves.Chenopodium glaucum and Atriplex sibirica are Recretohalophyte.Chenopodium glaucum had two-cell salt glands,while Atriplex sibirica had salt vesicles.The idioblasts and crystal cells in Atriplex sibirica and Chenopodium glaucum played an active role in adapting to the salt conditions.Observing from the epidermis cells of leaves,the 4 halophytes had the same drimophilous characteristic.In a whole,the leaves of 4 halophytes of Chenopodiaceae had common and diverse characteristics to adapt to the salt surroundings.
