二色补血草叶片泌盐结构的扫描电镜观察

对二色补血草盐泉结构进行比较研究，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。

ESM observation of secretory salt structure in Limonium bicolor leaf

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.
