Abstract EN
Osmanthus fragrans Lour., an evergreen small tree, has the rare sexual system of androdioecy (coexistence of males and hermaphrodites), once with wide-spread natural distribution in the areas of the South Yangzi river basin.
However, due to excessive human utilization, natural distribution became fragmented and the number and size of natural populations reduced sharply.
With four different types of natural populations from the same region as research object, we aim to provide a comparative analysis on the relationships among genetic diversity, sexual system, population structure and size, and geographic isolation by ISSR.
In genetic parameters of Ne, He, and I, the LQGC population had the highest value and the LQZGQ population had the lowest value.
These indicated that LQGC population showed the highest genetic diversity, followed by QDH and JN population, and LQZGQ population exhibited the lowest genetic diversity.
Genetic diversity in populations is closely related to population structure, reproduction mode, and sex ratio.
However, there seems to be no obvious correlation between genetic diversity and population size.
The results of AMOVA showed that genetic variations mostly occurred within populations.
It indicates that no significant genetic differentiation among populations occurs, and geographic isolation has no significant effect on genetic diversity.
