Abstract:

Genome DNA was extracted by the inproved method from leaves of Cynodon dactylon(L.) Pers,Zoysia spp,Eremorchloa ophiuroides.The detection performed on a nucleic acids and protein analyzer showed that A260/A280 were situated between1.74~1.98,A260/A230 were ranged from 1.74 to 1.99.The extracted products had a bright band and without tailing bands which could be observed through agar gel electrophoresis. These results showed that genomic DNA obtained by optimum methodWhich had a good integrity and high purity,and could be used in each kind of molecular biology research.
