Abstract: Studies on the structure of salt gland of Limonium bicolor leaf show that being different with other halophytes, Limonium bicolor flower-like salt glands in its lower epidermis of leaf, which consist of basic and cap cells.The salt release of plant is relied on the salt-secreting holes of salt gland and the broken of basic cells, indicating that this plant has a highly evolved structure of two-ways secreting salt, which makes the plant can grow on saline-alkali soil without any suffering from salt damage.

Key words: Halophyte, Secretory salt structure, Salt gland, Scanning electron microscopy, parameter optimization, maximum rate of carboxylation, gross primary productivity, BEPS model, maximum potential rate of electron transport.
