【摘要】 对二色补血草（Ｌｉｍｏｎｉｕｍｂｉｃｏｌｏｒ）盐腺结构进行比较研究，发现二色补血草叶下表皮具有花型盐腺，这些盐腺是由基细胞和帽细胞构成．植物体靠盐腺的泌盐孔和基细胞破碎释盐，表明二色补血草具有演化较高级的双重泌盐结构，是二色补血草能在盐碱地生长而不受盐害的主要原因．更多还原

【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.更多还原
