Phenotypic Characteristic Diversity of Different Cinnamomum camphora in Sichuan Province
In order to understand the phenotypic characteristics and diversity of C.camphora leaves,fruits and seeds of different provenance in Sichuan province,the leaves,fruits and seeds of six different provenance camphor trees were used as test materials to study the phenotypic variation by correlation,clustering and redundancy analysis.The results show that the variation coefficient of leaf phenotypic of different provenance C.camphora in Sichuan province rangs from 17.82%to 44.27%,with a mean value of 24.89%,among which the variation coefficient of leaf area is the highest(44.27%);the variation coefficient of fruit and seeds rangs from 5.87%to 38.22%,with a mean value of 11.30%.Compared with the leaves,the variation coefficient of C.camphora fruit and seeds are relatively more stable and less affected by the environment.Correlation analysis shows a significant correlation between the respective phenotypic characters,including leaves,fruits and seeds in Sichuan province,however,the correlation between the phenotypic characters of these three types is relatively insignificant.The cluster analysis shows that 6 provenances are grouped into two categories when the Euclidean distance is 4.The first provenance includes Yilong county,Cuiping district,Anyue county and Xuzhou district,and the second provenance includes Nanbu county and Shehong county.Rich phenotypic traits in C.camphora leaf,including leaf area,leaf perimeter,leaf length,leaf width,leaf margin factor and leaf shape index show a geographic variation pat-tern dominated by longitude and latitude,indicating that the phenotypic traits of camphor leaf have a high fit with longitude and latitude.
