栽培与野生丹参根解剖结构比较研究

A Comparative Study on Anatomical Structures of Roots between Cultivated and Wild Salvia miltiorrhiza

研究了栽培与野生丹参根的解剖结构.结果表明,在解剖横切面上,栽培与野生丹参根的周皮、韧皮部、木质部具有显著差异.栽培丹参根的周皮细胞层数少、色淡,韧皮部与木质部比值小,而野生丹参根的周皮细胞层数多、颜色重,韧皮部与木质部比值大.

Studies were conducted on the anatomical structures of roots of cultivated and wild salvia miltiorrhiza .The results showed that the root transactions had significant differences in periderm, phloem, and xylem between cultivated and wild Salvia miltiorrhiza. In cultivated Salvia miltiorrhiza roots, light-colored periderm contained less layers of cells and low ratio of phloem to xylem, compared with those in wild Salvia miltiorrhiza roots.
