三个竹属植物的成熟茎上的基因分布受一个隐藏的普遍规律支配，在竹笋阶段可以通过竹笋的基部直径来确定。摘要：竹子具有独特的结构特性，使其区别于大多数木本植物。最显著的特性之一是，长空心秆被一系列的节分隔成许多小室。节点沿茎的分布一般在茎中部稀疏，在茎末端密集。本文研究了毛竹属（Phyllostachys pubescensMazel ex Houz） 3种植物节点分布的种内和种间变异。,植被类型nigravar。不同茎粗的竹属植物（henonisys, phyllostachys nigramo）。通过归一化过程，节点分布遵循单一拟合曲线，表明存在一个隐藏的普遍规律，该规律支配着三种物种的节点分布，尽管它们的外观不同。研究结果还表明，在竹笋期，竹节沿成熟茎的分布可以通过竹笋基部直径来确定。
Key messageNode distribution along the mature culm of threePhyllostachysspecies is governed by a hidden universal law and can be determined at the bamboo shoot stage by its base diameter.AbstractBamboo exhibits unique structural properties that distinguish it from most other woody plants. One of the most remarkable properties is that the long hollow culm is separated into many small chambers by a sequence of nodes. The node distribution along the culm is, in general, sparse at the mid-culm and dense near the ends of the culm. In this study, we examined the intraspecific and interspecific variation in the node distribution of three species of the genusPhyllostachys(Phyllostachys pubescensMazel ex Houz.,Phyllostachys nigravar.henonisandPhyllostachys nigraMunro) with different culm sizes. The node distribution followed a single fitting curve via the normalization procedure, indicating the existence of a hidden universal law that governs the node distribution of the three species, despite their different appearances. Our findings also suggest that the node distribution along the mature culm could be determined at the stage of bamboo shoot by its base diameter.
