Genetic Variations and Relationships of Persicaria thunbergii(Sieb. & Zucc.) H. Gross ex Nakai(Polygonaceae) by the RAPD Analysis

摘要: RAPD analyses were performed from twenty-four populations of Persicaria thunbergii(Sieb. & Zucc.) H. Gross ex Nakai. The length amplified DNA fragments ranged 200 to 1,900bp. 184 scorable markers found PCR reactions with sixteen random oligoprimers. Based on the results, thunbergii classified into disturbance streams urban and rural as well natural streams. And showed having higher genetic similarites than those highly disturbed streams, Also, heterogenetic differences between areas could be represented results stream environmental changes.
