中华补血草的解剖结构与光合特性初探

Primary Sutdy on the Anatomic Structure and the Photosynthesis Characters of Limonium sinense

中华补血草是江苏沿海滩涂分布的一种泌盐保护植物,全草含黄酮体和杨梅树皮甙等多种有效成分,不仅可药用和观赏,还能改善盐碱地的土壤结构,故被誉为盐碱地改造的“先锋植物”。中华补血草为肉质根,初生木质部三原型;花序轴呈五棱型,表皮内为多层栅栏组织组成;莲座状叶,表皮细胞上有花朵状盐腺分布;由卷伞花序组成宽大的圆锥花序,花冠呈漏斗状;光合作用日变化为双峰曲线,叶绿素含量在中午11:00左右最高,为2.48 mg/L。

Limonium sinense, which is widely existed in seashore of Jiangsu to safeguard plants excreting salts. It has many effectual colchis such as flavone and glucoside of waxberry bark. So it can be used for not only medicine but also the improvement of the salt soils. For these, it is complimented as ＂the Pioneer Plant＂. Limonium sinense ,which roots is full of succulence, the original xylem is like triarch, the caudex is like five arris, the foliage is like the lotus pedestal, the salt-gland is like flower, the corolla is like the filler. Changes of photosynthesis curve has the characters of two zeniths. The highest content of chlorophyl is 2.48 mg/L at llO＇clock in morning.
