摘要：

Amplified fragment length polymorphism (AFLP) markers were used to investigate the genetic variations within and among nine natural populations of Hibiscus tiliaceus in China. DNA from 145 individuals was amplified with eight primer pairs. No polymorphisms were found among the 20 samples of a marginal population of recent origin probably due to a founder effect. Across the other 125 individuals, 501 of 566 bands (88.5 %) were polymorphic, and 125 unique AFLP phenotypes were observed. Estimates of genetic diversity agreed with life history traits of H. tiliaceus and geographical distribution. AMOVA analysis revealed that most genetic diversity resided within populations (84.8 %), which corresponded to results reported for outcrossing plants. The indirect estimate of gene flow based on phi(ST) was moderate (N-m = 1.395). Long-distance dispersal of floating seeds and local environments may play an important role in shaping the genetic diversity of the population and the genetic structure of this species.
