Abstract

Moso bamboo (Phyllostachys edulis (Carriere) J. Houzeau), native to China, is one of the most economically and ecologically important bamboo species. Since the economic interests and the strong clonality, it has been widely cultivated in southern China, which inevitably reduces the natural stands and leads to gene loss in this species. In this study, three natural populations of Moso bamboo distributed in Anhui, Guangxi, and Zhejiang province, were used to analyze the correlation between phenotypic traits, cell structure, and material properties from the perspective of phenotypic, genetic, and environmental. Among those traits and properties, fiber width was correlated with wall thickness at breast height and average nodes length under branch positively. Leaf length was correlated positively with fiber lumen diameter and parenchyma lumen diameter. Furthermore, it showed a very close correlation between moisture content, bending strength, modulus of elasticity, and diameter at breast height, clear height, and leaf length. The lumen diameter of fiber cell wall thickness is positively correlated with bending strength and modulus of elasticity. Density is positively correlated with parenchyma cell wall thickness. The experimental design is relatively detailed and representative, and the workload is huge. This study reflects the research objectives with scientific and rational experiments and data. This study will analyze the differences of various indicators from the perspective of genetic to build a bridge between micro-structure and macro-structure for rational utilization of the whole area of Moso bamboo resources in China.

Highlights

Introduction iationsBamboo is an important non-woody forest resource rich in natural lignocellulose.The global annual output of bamboo is about 1.5 billion, and continuously regenerated bamboo is an important alternative resource for about 1/2 of the annual wood gap (250 million m3 ) [1,2]
In order to investigate the variation of phenotypic traits of Phyllostachys edulis distributed in different subtropical provenance regions, 209 samples of Moso bamboo distributed in Anhui, Guangxi, and Zhejiang province were obtained
The phenotypic correlation was 0.606(0.793), 0.393(0.797) and 0.346(0.88). It showed that the larger diameter at breast height (DBH) is, the longer node length at DBH (NL_DBH) is, and the thicker Wall thickness at DBH (WT_DBH) is

Summary

Introduction

Bamboo is an important non-woody forest resource rich in natural lignocellulose. The global annual output of bamboo is about 1.5 billion, and continuously regenerated bamboo is an important alternative resource for about 1/2 of the annual wood gap (250 million m3 ) [1,2]. China is one of the distribution centers of bamboo plants, ranking first in the world in terms of bamboo species, storage, and area [3,4,5]. There are more than 800 bamboo species in China, which contains more than 1/3 of the bamboo species of the world. Houz.) is one of the core bamboo species in the development of the bamboo industry, which has the widest distribution area, the highest output value, and the best industrial utilization in China. Under the background of modern forestry advocating “developing bamboo in place of plastic, timber and steel substitute”, it is important to accelerate the utilization and research
