Analysis Of Genetic Diversity Of Saposhnikovia Divaricata (Turcz.) Schischk In Different Populations

Saposhnikovia divaticata(Saposhnikovia divaricata (Turcz.) Schischk.) of umbrelliferae perennial officinal plant. With the medicine, have antipyretic sweating qufeng analgesia effects for common use Chinese herbal medicine. In our Chinese herbal medicine market, the Saposhnikovia divaticata of the materials in pharmaceutical quality in heilongjiang province for top grade, has the quality of a material is solid closely, the root skin is red brown, cross-sectional chrysanthemum core obvious, called article red goods. And other area production Saposhnikovia divaticata of poor quality, the quality of a material is loose, the root skin is ash brown, cross-sectional chrysanthemum core is not apparent, called white goods. So the Saposhnikovia divaticata is one of our province specialty of medicinal materials. But, in recent years due to excessive cultivation, grassland area reducing, plus the excavation of predatory, serious damage the ecological balance, make the wild Saposhnikovia divaticata plant community reduce year by year, resource is drying up. So, stop the excavation of, expand cultivated area, to play the geography and resources, traditional Chinese medicinal materials to meet the demand of the market, to have the important meaning.This research use seeds quality standards and SSR molecular markers, combining physical appearance and explain different provenance Saposhnikovia divaticatabreak and genetic diversity, and the results are as followsThrough different provenance of seeds for Saposhnikovia divaticatabreak and-grain weight, clarity, moisture content, life force, seed germination rate and physiological indexes found that different provenance Saposhnikovia divaticata in seed in appearance,-grain weight, water content are clearly different. One of the most obvious differences between-grain weight. Inner Mongolia of Chifeng Yongfeng significantly greater than other provenance, and-grain weight of Heilongjiang province in Daqing cityLindian obviously less than other provenance.Use of SSR molecular markers of Saposhnikovia divaticata different provenance method is analyzed,10to SSR primer response measures against the average effective alleles digital2.3244, Nei diversity index for04180, Shannon index for09632, group differentiation coefficient for0.2412. Inner Mongolia chifeng city of genetic diversity is much higher than in other areas of the Saposhnikovia divaticata provenance, may cause analysis for the region and weather...
