[Preliminary analysis and isolation of genomic total DNA in Fritillaria thunbergii Miq].

Genomic total DNA of leaf, fresh scale and dry scale in Fritillaria thumbergii were isolated by two different methods and analysed by agarose gel electrophoresis. The results show that the DNA contents are different under these two isolating methods. Two bands besides the band of genomic total DNA have been found by electrophoresis, these two bands deserve further study.
