Introduction test and ISSR analysis of Pinus contorta in semi-dry region of Jilin Province,China;

Method: Seven wild populations of Changium smyrnioides and one cultivated population of Chuanminshen violaceum were studied by ISSR analysis.

5% SDS,adding chloroform can effectively inhibit the activity of DNase and remove the impurity of protein when the sample was grinded,and the DNA with good quality and high concentration can be extracted once by chloroform/isopentanol(24/1) analysis,which can meet the needs of ISSR analysis.
