摘要：Objective: The phenotypic traits of pod and seed from an endangered plant Erythrophleum fordii were measured to investigate the phenotypic diversity and variation pattern of populations. And combing with geographical and climatic information, the factors affecting the phenotypic variation were discussed. This study provides a basis for genetic diversity conservation, restoration, and cultivation of E. fordii. Method: The phenotypic characteristics of thirteen pods and seeds from 114 individuals of eight natural populations were measured. Nested analysis of variance, multi-comparison, correlation analysis, principal components analysis, and cluster analysis were used to study phenotypic diversity, evolution and adaptive potential, patterns of phenotypic variation, level of phenotypic differentiation, cluster of populations, and the correlation between phenotypic traits and climate factors, respectively. Result: E. fordii showed a modest level of phenotypic diversity, the range of Shannon-Wiener index is from 1.911 1 (Shape index of seed) to 2.103 9 (Perimeter of pod)with an average of 2.027 8. The range of Shannon-Wiener index of eight populations is from 0.920 9(P6)to 1.885 6(P8) with an average of 1.474 7. The range of variation of variance among the 13 traits was from 7. 544 6% (Length of seed)to 18.868 5%(Area of pod)with an average of 12.410 9%. The range of variation of variance among the eight populations was from 8.852 9%(P1) to 13.984 8%(P5) with an average of 12.410 9%. The range of times of maximum and minimum was from 1.395 2(Shape index of seed) to 2.805 6(Number of seeds in pod)with an average of 1.791 7. Analysis of nested variance showed that there was a significant differences (P ? 2019, Editorial Department of Scientia Silvae Sinicae. All right reserved.
