Normally, the 3- to 5-year-old bamboo could be harvested for manufacturing of some industrial products (Scurlock et al. Bamboos are one of the fast-growing and renewable non-timber plants with good mechanical properties. Keywords: Moso bamboo Modulus of Rupture Compressive strengths Three-layer structure AgeĬontact information: a: School of Forestry and Landscape Architecture, Anhui Agricultural University, Hefei 230036, China b: Co-Innovation Center of Efficient Processing and Utilization of Forest Resources, Nanjing Forestry University, Nanjing 210037, China *Corresponding author: has abundant bamboo resources and ranks first in both the area of bamboo forest and the annual yield of bamboo produced in the world. Ge Han, a Rongrong Li, b and Chuangui Wang a,* These results provide an important basis for the bamboo used in engineering.Įffects of Three-layer Structure and Age on Mechanical Properties of Moso Bamboo However, the inner layer of bamboo is relatively brittle, which has negative effects on its flexural strength. The outer layer of bamboo with high toughness and flexibility played an important role during bending. However, for the samples without bamboo inner layer, the parallel-to-grain compressive strength remained unchanged, but the flexural strength increased. For the moso bamboo with same age, the flexural and parallel-to-grain compressive strengths decreased for the samples without bamboo outer layer. The mechanical strength of moso bamboo increased with the increased age of moso bamboo. The results showed that the age of moso bamboo was positively correlated with the flexural and parallel-to-grain compressive strengths. The regression analysis was completed to evaluate the relationship between mechanical properties and bamboo age. The ages of 1-, 3-, and 5-year-old bamboo were chosen to make test samples, and specimens from each age of moso bamboo were divided into three groups (raw bamboo, bamboo removed from outer layer, and bamboo removed from inner layer) for evaluation of modulus of rupture and parallel-to-grain compressive strength. The effects of a three-layer structure and age on the mechanical properties of moso bamboo were investigated.

She is also Principal Coordinator and chief scientist of the National Key R&D program of China.Han, G., Li, R., and Wang, C. Recently, she has been awarded with the Women's model by the State Forestry Administration of China. She has served at prestigious positions in academia including as Dean of Forestry department in Anhui Agricultural University, Vice Director of Taiping experimental station, and Principal Scientist of ICBR. WONG, and won several awards by China Forestry Society, and national awards including the Ten million talents project of State Forestry Administration. She has been honored with special allowance recipients of Anhui Provincial Government, Fellowship from DAAD-K. Her current area of research includes genome and transcriptome analyses in bamboo, mainly toward deciphering molecular mechanism of bamboo flowering and bamboo shoot fast growth. Jian Gao is an internationally reputed scientist with an illustrious professional career of spanning over thirty-four years and original contributions in the fields of plant genomics, molecular ecological physiology, and molecular breeding leading to the publication of more than 150 quality research articles and reviews, more than 10 chapters have been written for several books, including those published by FAO and edited five books. This book appeals to graduate students, post-graduate students, research scholars, researchers, and industry players in the field of plantation bamboo in general, bamboo processing and bamboo garden owner and fans of bamboo culture in particular. Altogether, the book comprises eleven chapters covered over 200 pages authored by the researchers involved in genomic science, molecular biology, and breeding. This book is the first comprehensive compilation describing the botanical traits, genetic resources, whole genome sequencing, Mitochondrial genome, transcriptomes of different organs with developmental stages, transcription factors, delineating gene evolution of gene family in Bambusoideae, alternative splicing (AS) and polyadenylation, case studies for economically important traits such as internode length, shoot fast growing, flowering, ageing and stress-resistant genes and small RNAs-mediated gene regulation of moso bamboo flowering and other developmental stages.Īpplications of transcriptome and genome approaches in moso bamboo in general and the prospects of transgenic breeding and genome editing technologies in bamboo are also discussed.
