5. Conclusion
This study provides valuable insights into the genetic diversity and
population structure of the critically endangered C. hainanense within
fragmented habitats in Hainan. The findings contribute to our
understanding of the impact of habitat fragmentation on genetic
diversity in plant populations and inform conservation efforts for other
endangered plant species within fragmented ecosystems.The genetic
diversity of C. hainanense was low, and the heterozygosity of the
six populations of C. hainanense ranged from 10.79% to 14.55%.
The average heterozygosity was 13.15%. Six C. hainanense
population into the population (Diaoluoshan, Baishaling) and population
(Wuzhishan, Huishan, Bawangling, Jianfengling) the two population. In
addition, the genetic differentiation among C. hainanensepopulations is weak.
