毛竹（Phyllostachys pubescens）是中国亚热带森林生态系统中重要的非木材林产品（NTFP）。在这项对幼竹的研究中，通过 13 C 核磁共振 (NMR) 技术测定了高度、生物量和碳积累的动态变化，并分析了组织样本。结果表明，从竹笋萌发到形成幼竹的时间为35~40 d。幼竹生物量和碳的积累主要取决于地径和竹笋发芽后的时间长短。组织样品的NMR谱表明，O-烷基碳在组织碳中占主导地位，约占70%。不同碳形态的相对比例随着幼竹的生长没有显着变化，表明不同碳形态在幼竹生长过程中的碳积累是稳定的。
Moso bamboo (Phyllostachys pubescens) is an important non-timber forest product (NTFP) in the forest ecological system of subtropical China. In this study of young bamboo, dynamic changes in height, biomass, and carbon accumulation were determined and tissue samples were analyzed by13C-nuclear magnetic resonance (NMR) technology. Results showed that the time from the bamboo shoots sprouting to the formation of young bamboo was 35–40 d. Accumulation of biomass and carbon in young bamboos depended mainly on ground diameter and the length of time after the bamboo shoots sprouted. NMR spectroscopy of tissue samples showed thatO-alkyl carbon was found to dominate the tissue carbon, and it accounted for approximately 70%. The relative ratios of different carbon forms did not significantly change with the growth of young bamboo, suggesting that different carbon forms were stable with the carbon accumulation in the growth period of young bamboo.
