![]() ![]() Conclusions Removal of plants from the wild for horticulture purposes has eroded the level of genetic variation of N. ![]() ![]() Based on analysis of molecular variance, a high degree of among-population differentiation was revealed for both natural (0♳87) and cultivated populations (0♵98). The cultivated populations (PPB = 18♹ %, H E = 0♰60, S = 0♰92) were genetically less diverse than the natural populations (PPB = 23♱ %, H E = 0♰82, S = 0♱23). sericea exhibited low levels of genetic variation. Despite being a woody, long-lived, perennial, outcrossing and insect-pollinated plant, N. Key Results A total of 99 discernible loci were obtained for all populations using ten primers, 50♵ % of which were polymorphic.Methods Levels and patterns of genetic diversity in 114 individuals from six natural populations and four cultivated populations of the insular endangered plant Neolitsea sericea (Lauraceae) on the Zhoushan archipelago were assessed using random amplified polymorphic DNA (RAPD) markers.Because of the long-term influences of human activities, the original forest vegetation on the large islands has been badly damaged and its plant diversity reduced. It separated from the mainland about 9000 years ago due to rising sea levels and climate change. Background and Aims The Zhoushan archipelago is the largest archipelago in China.
