“…Second, compared to wind‐pollinated species, pollen of insect‐pollinated species (such as most species in Lauraceae, Li et al., 2018; Rohwer, 1993) disperses over shorter distances, resulting in limiting gene flow and increased genetic differentiation. For example, the pollinators of Neolitsea sericea (Blume) Koidz.…”

“…Phoebe zhennan (Lauraceae) is a diploid (2 n = 24), dioecious tree up to 30 m tall which produces purple‐brown drupes and grows in subtropical evergreen broad‐leaved forests (EBLFs) of China (Li, Li, & van der Werff, 2008). Chinese Phoebe L. species are insect‐pollinated, and the seeds are dispersed primarily by frugivorous birds (Li et al., 2008; Li, Liu, Ma, Zhang, & Xu, 2018). Phoebe zhennan is the major source of the well‐known wood “Golden‐thread nanmu,” which is extremely valuable due to its durability, unique special fragrance, and attractive golden color.…”

Docynia delavayi (Franch.) Schneid. is a wild fruit tree, which can be widely used for medicinal and edible with a high value of exploitation and utilization. To gain greater insight into the genetic variation of growth traits in D. delavayi, we investigated the growth traits of a total of 62 half-sib families from 10 provenances. Based on the data of growth traits, variation analysis, correlation analysis, principal component analysis, estimation of genetic parameters and comprehensive analysis were carried on. The results of variance analysis showed that all traits, except for branch length, were significant or extremely significant differences among provenances, while among families, only leaf width showed no significantly different. The results of correlation analysis showed that all growth traits, except for branch length and petiole length, had a significant or extremely significant correlation with the geo-climatic factors. Three principal components were extracted by principal component analysis, they were used as indicators for the comprehensive evaluation of D. delavayi from different provenances, and five excellent provenances were selected (LC, LH, SD, YJ, XY). The results of genetic parameters estimation showed that all indicators except leaf length and leaf width had a high potential for genetic improvement. Therefore, five traits (SH, GD, BL, PL, TNL)were used as comprehensive index to select superior families, and a total of 20 superior families were selected. This study will lay a theoretical foundation and practical guidance for the genetic improvement of D. delavayi.

“…(Day Rubestein et al, 2006;Upadhyaya et al, 2008). Phenotype is one of the most important means of studying diversity and is the most direct expression of plant adaptation to the environment (Li et al 2018). Evaluating the diversity of plant phenotypes is conducive to the protection and utilization of plants.…”

Docynia delavayi (Franch.) Schneid. is a wild fruit tree with high medicinal, edible, ecological, and ornamental values. This paper investigates the phenotypic diversity of nine traits in fruit and leaf from 17 Docynia delavayi natural populations. The results of coefficient of variation showed petiole length and leaf area contributed the highest mean coefficient of variation (CV = 36.85% and 43.71%, respectively), while fruit vertical diameter had the lowest contribution index (CV=12.17%). The principal component analysis (PCA) revealed that first six PC axes explained 95.417% of the total variance among the Docynia delavayi populations tested, and the first three PCs explained 76.413% of the variation in multiple traits. PC1 was the most important genetic factor and the main indicator of its interpopulation variation, accounting for 51.428% of the total variation. Based on the nine phenotypic data of leaf and fruit from 17 natural populations of Docynia delavayi, the UPGMA method was used to broadly classify these populations into four main groups. This study provides a theoretical basis for further utilization and conservation of Docynia delavayi germplasm resources.
