5 CONCLUSION
Clonal architectures and diversity spatial pattern of different C.
udensis ploidies were the result of long-term adaptations to different
habitats. Both the diploids and tetraploids adopted reproductive
trade-offs to respond to different environments. As an autotetraploid,
the tetraploids through high clonal reproductive rates and genetic
diversity adapted to completely different habitats from their diploid
ancestors. The diversity model of two C. udensis ploidies were
anticipant to be consistent with the hypothesis about the
inter-polyploid. The results in this study will shed light on the
evolution of the intra-polyploid and be helpful to better elucidating
the adaptation mechanisms of facultative plant clones.
