A distance measure between plant architectures

چکیده
In many biological fields (e.g. horticulture, forestry, botany), a need exists to quantify different types of variability within a set of plants. In this paper, we propose a method to compare plant individuals based on a detailed comparison of their architectures. The core of the method relies on an adaptation of an algorithm for comparing rooted tree graphs, recently proposed by Zhang in theoretical computer science. Using this algorithm a distance between two plants is defined as the cost of transforming one into the other (using basic “edit operations”). We illustrate this method in three application fields and then compare it with other methods for quantifying plant similarity. topological structure of plants / plant comparison / analytical method Résumé – Définition d’une distance entre architectures de plantes. Dans de nombreux domaines de la biologie (arboriculture, sylviculture, botanique), il est nécessaire d’étudier différents types de variabilité au sein d’une population de plantes. Nous proposons, dans ce papier, une méthode de comparaison des plantes basée sur une comparaison détaillée de leur architecture. Cette méthode est une adaptation d’un algorithme de comparaison d’arborescences, proposé récemment par Zhang en informatique théorique. Cet algorithme nous permet de définir une distance entre deux plantes comme le coût de la transformation de l’une en l’autre (à l’aide d’opérations élémentaires d’édition). Cette méthode est illustrée dans trois domaines d’application et elle est comparée à d’autres méthodes de quantification de la ressemblance entre plantes. structure topologique des plantes / comparaison des plantes / méthode analytique

متن کاملHigh-Resolution Laser Scanning Reveals Plant Architectures that Reflect Universal Network Design Principles.
Transport networks serve critical functions in biological and engineered systems, and yet their design requires trade-offs between competing objectives. Due to their sessile lifestyle, plants need to optimize their architecture to efficiently acquire and distribute resources while also minimizing costs in building infrastructure. To understand how plants resolve this design trade-off, we used h...
متن کاملPlant architecture comparison methods: A review of existing algorithms and examples of application
Introduction Among a number of generic tools that have been developed in the last decade to measure, explore, analyze, model and visualize plant architecture in 3-dimensions, this paper focuses on methods dedicated to the comparison between plant architectures. After a first step that has been reached with the comparison of branching sequences along axes (Guédon et al., 2003), Ferraro and Godin...
متن کاملEvaluation of Distance and Quadratic Indices for Determination of Plant Species Distribution Pattern in Khoosef Rangelands, Birjand, Iran
One of the major issues examined in the quantitative ecology is the spatial distribution pattern of plant species. Knowledge of the spatial distribution patterns is essential to measure the level of uniformity in the surrounding environment, plant reproduction, and distribution of the seedlings, plant behavioral patterns, coexistence, allelopathic relations, and competition. Therefore, the aim ...
