Variation in internode length patterns: a data analysis of internode length and serial number in three bamboo species
IntroductionBamboo is one of the fastest-growing plants on earth, and its young culms are formed by the elongation of internodes. However, the mathematical intricacies of its internode elongation are not well understood.MethodsThis study investigated the internode length growth of Phyllostachys edulis, Phyllostachys iridescens, and Pseudosasa amabilis at ten different culm height developmental stages (G1–G10).Results and discussionThe tempo of internode elongation from the culm base to the tip generally followed a “slow-fast-slow” growth rhythm. The internode length and the serial number relationship showed a right-skewed curve. As the bamboo grows taller, the longest internode moves from the base to the middle of the culm. The relationship between relative internode number (RIN) and relative cumulative internode length (RCIL) displayed a typical S-shaped growth curve. The modified Brière (MBE) sigmoid equation achieved better goodness-of-fit than the logistic, power, and third-order functions in fitting the RIN-RCIL curves with the smallest average root mean square error (RMSE). The elongation rates of internodes varied not only with the growth of culm height, but also with the position of the bamboo culm from base to tip. In addition, as the bamboo grows in height, more internodes gradually contribute to the culm height growth. At G1 development stage, 24.01–38.23% of the internodes contributed 65.27–73.59% of the culm height, whereas at G10 stage, 49.28–61.07% of the internodes contributed 66.70–78.18% of the culm height. Our findings provide new insights into the mathematical characterization of bamboo internode elongation patterns involved in the rapid culm growth.
期刊介绍:
Frontiers in Ecology and Evolution publishes rigorously peer-reviewed research across fundamental and applied sciences, to provide ecological and evolutionary insights into our natural and anthropogenic world, and how it should best be managed. Field Chief Editor Mark A. Elgar at the University of Melbourne is supported by an outstanding Editorial Board of international researchers. This multidisciplinary open-access journal is at the forefront of disseminating and communicating scientific knowledge and impactful discoveries to researchers, academics and the public worldwide.
Eminent biologist and theist Theodosius Dobzhansky’s astute observation that “Nothing in biology makes sense except in the light of evolution” has arguably even broader relevance now than when it was first penned in The American Biology Teacher in 1973. One could similarly argue that not much in evolution makes sense without recourse to ecological concepts: understanding diversity — from microbial adaptations to species assemblages — requires insights from both ecological and evolutionary disciplines. Nowadays, technological developments from other fields allow us to address unprecedented ecological and evolutionary questions of astonishing detail, impressive breadth and compelling inference.
The specialty sections of Frontiers in Ecology and Evolution will publish, under a single platform, contemporary, rigorous research, reviews, opinions, and commentaries that cover the spectrum of ecological and evolutionary inquiry, both fundamental and applied. Articles are peer-reviewed according to the Frontiers review guidelines, which evaluate manuscripts on objective editorial criteria. Through this unique, Frontiers platform for open-access publishing and research networking, Frontiers in Ecology and Evolution aims to provide colleagues and the broader community with ecological and evolutionary insights into our natural and anthropogenic world, and how it might best be managed.
