Twelve populations of L.pumilum were collected from southeast of Qinghai province.Eighteen morphologic characteristics of these samples were then determined,and the corresponding variance and diversities analyses were carried out.The results of variance analysis showed that there was significant difference in morphologic chatacteristics within or between the populations,and that the value of F was 3.7431~90.9985 between the populations and 2.6849~84.125within the populations,respectively.The mean variance p...
