摘要Rhododendron decorum is widely distributed shrub in southwest China, and its flower is a favorite food of the local people. To investigate the impacts of harvesting, we genotyped 8 nuclear microsatellite loci in a total of 247 individuals from 10 natural populations and 4 flower-harvesting populations. No significant differences in allelic richness, effective number of alleles, private allelic richness, heterozygosity and effective population size were found among the natural and flower-harvesting populations. Differentiation between the 14 populations is relatively low (F-ST = 0.107). R. decorum showed high levels of intra-population genetic diversity. AMOVA analysis indicated that over 89% of the variation was contained within the populations, and that only 0.47% of the variation was attributed by human harvesting practices. Cluster analysis revealed two basic clusters related to the plants' geographical locations. Our results indicate that historical flower-harvesting practices do not lead to loss of genetic variation in R. decorum. (C) 2013 Elsevier Ltd. All rights reserved.
