Snow damage is problematic when cultivating bamboo shoots, and “Uradome”, the practice of removing the tips of new shoots, is used as a preventative measure. Producers perform “Uradome” at empirical times, but there is no scientific basis for this. We hypothesized that differences in the structure and composition of the cell wall might affect the optimal timing of "Uradome" and analyzed the cell wall components of the “Uradome” portion. The lower plant sections broken by the “Uradome” had larger cellulose and lignin depositions than the upper sections. However, there were no differences in the lignin structure or ratio between the upper and lower nodes of the broken sections. This suggests that differences in the degree of cellulose and lignin deposition have significant effects on “Uradome” sites, and that the timing coincides with the development of one or two juvenile branches, which growers empirically consider to be the appropriate time. These results are considered to be new findings that scientifically support the cultivation management of bamboo that has been conducted empirically.

评估细胞壁组成对毛竹中“ Uradome”最佳阶段的影响

栽培竹笋时，雪灾是一个问题，因此，使用“ Uradome”（一种去除新芽梢的做法）作为预防措施。生产者在经验时期执行“ Uradome”，但是这没有科学依据。我们假设细胞壁结构和组成的差异可能会影响“ Uradome”的最佳时机，并分析了“ Uradome”部分的细胞壁成分。被“ Uradome”打碎的下部植物部分比上部植物具有更大的纤维素和木质素沉积。但是，断裂部分的上节和下节之间的木质素结构或比率没有差异。这表明纤维素和木质素沉积程度的差异会对“ Uradome”位点产生重大影响，时机恰好与一到两个幼年分支的发展相吻合，从经验上讲，种植者认为这是合适的时间。这些结果被认为是新的发现，科学地支持了凭经验进行的竹子栽培管理。
