To compare the application of traditional morphometric methods(TMMs)and geometric morphometric methods(GMMs)in the study of intraspecific leaf morphological characters of quercus dentata,fifteen linear measurement indices and thirteen landmarks of leaves were used to study leaf morphology of three provenances(H1,H2,and H3).In TMMs,principal component analysis(PCA)showed that leaf size–related indices played an important role in population *** least square(PLS)analysis showed that the main morphological characters affecting leaf size were the average depth of the lobes and the length–width ***,the important indices to distinguish the provenances were circularity,leaf width,and length–width *** results of discriminant analysis(DA)showed that 74.0%of H1,68.0%of H2,and 74.0%of H3 were correctly *** analysis showed that the Mahalanobis distances between H1 and H2,H1 and H3,and H2 and H3 were 4.3761,11.4629,and 10.2067,*** GMMs,PCA based on symmetrical components showed that the difference in leaf morphology was mainly due to the changing trend of the leaf apex and base,petiole length,and degree of leaf *** analysis showed that there was a significant covariation between the leaf symmetrical components and size:as the leaf enlarged,the widest part gradually moved up,and the shape changed from nearly oval to *** results showed that 86.0%and 78.0%of H1 and H2,70.0%and 80.0%of H1 and H3,and 82.0%and 76.0%of H2 and H3 were correctly *** variate analysis results showed that the Mahalanobis distances between H1 and H2,H1 and H3,and H2 and H3 were 1.7238,1.5380,and 1.6329,*** GMMs and TMMs showed significant differences in morphology among the three *** provenances,but GMMs had higher classification accuracy and could provide more information about leaf shape,whereas TMMs could provide more information about leaf *** on our results,GMMs are promising in t

Here, we report the complete chloroplast(cp) genome of the daimyo oak, quercus dentata Thunb. The genome is 161,250 bp in size with a GC content of 36.83% and contains 134 genes(86 protein-coding genes, 40 tRNA genes, eight rRNA genes). The large single-copy region and small single-copy region in the cp genome contain 90,560 bp and 19,036 bp, respectively, while the inverted repeat region is 25,827 bp in length. The phylogenetic analyses based on the whole cp genome sequence provided a solid evidence that Q. dentata has a close relationship with Q. aliena. The presence of two subgenus, quercus and Cyclobalanopsis, in quercus was uncovered in the phylogenetic analyses. The cp genome presented here will provide useful information for the phylogenetic and evolutionary studies of quercus species.
