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.
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.
