Abstract Aims Axial parenchyma (AP) and ray parenchyma (RP) in secondary xylem have many important ecological functions, such as storage and translocation. Quantifying the compositions of parenchyma in secondary xylem will benefit the further research about their functions. However, the understanding of parenchyma compositions in current-year branches is still lacking. Methods Eighteen woody saplings in the Tianma National Nature Reserve were selected for sampling. The proportions of cross-sectional area occupied by AP and RP were measured. The variations in parenchyma among species and their phylogenetic signals were analyzed. Compared with the related dataset, the differences between twigs and trunks were tested. Important findings (1) The proportions of total parenchyma in twigs of the 18 woody saplings were 9.96%-18.56%, with the average of 14.80%; the proportions of RP (7.74%-15.45%) were higher than that of AP (1.13%-7.49%). (2) The total parenchyma (RAP) in twigs was lower than that in trunks, of which, RP in twigs was lower than that in trunks while AP showed an opposite pattern. The differences between twigs and trunks may be caused by the differences between different organs and different life history periods. (3) Significant phylogenetic signal was detected in the amount of AP in secondary xylem of twigs. This study primitively verified the phylogenetic signal of the secondary xylem parenchyma, and suggested that the difference between organs, and the difference between life history periods, had important effects on the variations of parenchyma.

... 薄壁组织作为木本植物次生木质部的重要组成部分, 其总含量在被子植物中一般为20%-40%, 而在裸子植物中一般仅为5%-10% (Plavcová & Jansen, 2015).薄壁组织依据细胞排列方式和方向可分为射线薄壁组织(RP)和轴向薄壁组织(AP).薄壁组织执行着多种功能, 如物质存储(Plavcová & Jansen, 2015, Plavcová et al., 2016)和转运(Bel, 1990)、防御病原菌(Wheeler et al., 2007)以及机械支持作用(Burgert & Eckstein, 2001)等.木质部薄壁组织与导管、纤维等其他细胞类型存在含量上的权衡关系(Zheng & Martínez-Cabrera, 2013; Morris et al., 2016), 影响着木质部生理生态功能的发挥.目前国外对于木本植物薄壁组织含量、功能及其影响因素已有较多报道(Hearn, 2009; Olano et al., 2013; Spicer, 2014; Morris et al., 2016; Plavcová et al., 2016; Rungwattana & Hietz, 2018), 而国内对木本植物薄壁组织的研究还主要集中在植物器官解剖结构方面(谭海燕等, 2000; 胡云等, 2006; 卫星等, 2008; 郑国琦等, 2015), 但近年来国内也开始加强其含量和功能的研究.如郑国琦等(2010)曾报道宁夏枸杞(Lycium barbarum)根、茎中次生木质部薄壁组织含量与灌水量的关系; Zheng和Martínez- Cabrera (2013)用近800种国内树木的木质部性状(包括薄壁组织含量)数据研究了两种薄壁组织功能分化及其与支持、传导功能的权衡关系; Martínez- Cabrera等(2017)使用Zheng和Martínez-Cabrera (2013)的数据分析了近缘种薄壁组织含量变异性随进化时间的变化(Martínez-Cabrera et al., 2017). ...
