| [rapd analysis on the germplasm resources of gastrodia elata in guizhou]. | genetic polymorphisms of genomic dna of 15 samples from wild and culturaled gastrodia elata blume in guizhou were analyzed by rapd method. 12 effective primers are screened from 40 primers amplified a total number of 93 loci, among which 66 are polymorphic and the percentage of polymorphic loci (ppb) is 70.97%. upgma dendrogram analyzed by ntsyspc, ver. 2.2 shows that gastrodia elata have apparent genetic variance. geological distribution and growing environment were significant factors for the ... | 2006 | 17212036 |
