This paper reveals the main growth traits and genetic variation of secondary metabolites in the law, breeding varieties for the main purpose of the Zhejiang, Jiangxi, Fujian, Guangxi, Guangdong, Guizhou, Anhui, Sichuan and Yunnan of 9 provinces and 21 provenances Sarcandrae cell markers, molecular marker system for the main active components, to achieve the following results:1 Different kinds of sources Sarcandrae major agronomic traits, including plant height, diameter, sprout number, production Dengjun had significant differences. Among them, Jiangxixingan is the highest yield, highest of average height and the strongest suckering, Guangxidonglan is the most of coarse.2 Sarcandrae microstructure: a layer of leaf epidermis from the epidermal cells arranged in a close composition, cell wall thin cuticle, stomata only found in the lower epidermis; no palisade mesophyll and spongy tissue, veins developed; stem The crescent-shaped fiber tip in the column, circular arrangement, more than xylem tracheid, hip developed; powder characteristics of starch granules contain more, with inulin, glandular hairs, brown block, stone cell powders structure. 21 kinds of sources Sarcandrae fan stomatal length, width, aspect ratio, stomatal density, stomatal index were among provenances difference was very significant. And certain geographic variation law: stomatal length and width respectively, compared with the longitude was negatively correlated with elevation was significantly correlated; in the vein thickness and latitude had a significant positive correlation.3 By RAPD molecular markers Sarcandrae 21 kinds of main producing areas of the country source of the genetic diversity of germplasm resources, the results show that genetic diversity index was 0.1195. 62.51% of the variation of Sarcandrae existed among provenances and only 37.49% of variation within provenance.4 Measured by HPLC, Sarcandrae provenance field trials the main active ingredients components (rosmarinic acid, Isofraxidin) quality scores were very significant differences. The major source of active ingredients in different kinds of content there is a certain variation, isofraxidin higher levels of seed sources are concentrated in the central distribution, rosmarinic acid content was negatively related to longitude.
