TL;DR
This study analyzes the genetic diversity and gene flow of Liriodendron chinense in rocky desertification areas to support ecological restoration efforts.
Contribution
The study provides new insights into the natural regeneration and genetic structure of L. chinense in artificial mixed forests.
Findings
L. chinense shows moderate genetic diversity in rocky desertification areas.
Significant gene flow occurs primarily within short to medium distances (under 80 m).
Most pollen (63.2%) originates from within the sampling area, indicating local natural regeneration.
Abstract
Liriodendron chinense plays a crucial role in improving the ecological environment and combating soil erosion in the rocky desertification area of Western Hunan, China. However, there is still a lack of systematic research on the genetic diversity of natural populations of the L. chinense in rocky desertification areas. This study employed 11 simple sequence repeat (SSR) markers to analyze genetic diversity and spatial genetic structure in a population of 318 L. chinense individuals. We conducted parentage analysis on individuals from a limited area of natural regeneration to quantify pollen and seed-mediated gene flow separately. Based on diameter classification, L. chinense individuals in the large diameter class can be considered as potential parents. The results show that there is moderate genetic diversity in the natural populations of the L. chinense. The spatial genetic patterns…
