It has the capability of representing tree growth within a virtual space where the development of individual organs depends on geometrical traits. The purpose of this research is to investigate the influence of apple trees' architectural variability on their light interception efficiency. The STAR, i.e. the silhouette to total area ratio, of leaves, was chosen to evaluate the level of such efficiency. The strategy is to integrate MAppleT with the light interception model provided by the Fractalysis module of the VPlants software library. Target values of four major traits (internode length, leaf area, branching angle and top shoot diameter), are varied in range previously observed in a segregating population of apple hybrids. A sensitivity analysis based on polynomial and generalized additive models was performed for highlighting the most influential trait on light interception. The contribution of stochastic processes that control tree topology in MAppleT is also investigated in the sensitivity analysis. This study not only provides a time- and resource-saving alternative for data collection, but also sets a methodology for ideotype definition and further genetic improvement of apple trees.","PeriodicalId":117786,"journal":{"name":"2012 IEEE 4th International Symposium on Plant Growth Modeling, Simulation, Visualization and Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121475067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many modelling efforts have thus concentrated on correctly capturing its complex shape at different stages and use them as scalable geometric primitives. Still, additional control of such objects is needed in the context of Functional Structural Modelling. The objective of this work is to propose a plastic and dynamic 3D leaf model that is well suited for such uses, still able to capture a variety of observed static shapes. Leaf shape is modeled by a parametric surface describing leaf midrib curvature, leaf width variation, undulation of leaf margins and twist along the midrib. Meshes can be generated from these surfaces, and reduced using a decimation algorithm. The model can be fitted with data or with curves drawn by user interaction. Morphological operators are defined and allows for plastic deformation of the control curves. The dynamics of shape acquisition can also be specified, and combined with morphological operators to simulate various scenarios of evolution and responses to stresses. The capabilities of the model are demonstrated through several cases of use. Future directions of research are thought to be a better integration of mechanical or physiological constraints that would reduce the model plasticity but avoid user-induced unrealistic simulation.","PeriodicalId":117786,"journal":{"name":"2012 IEEE 4th International Symposium on Plant Growth Modeling, Simulation, Visualization and Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124759472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The work has focused on a case study, namely the irrigated district of Cherfech located in the governorate of Ariana, 25 km away from Tunis. The analysis concerns 63 farms covering an area of 850 ha during the 2010-2011 crop season. The achievement of this analysis was made possible using the MABIA-REGION software. Thus, daily Penman-Monteith reference evapotranspiration (ET0), effective precipitation (PE), dual crop coefficients (Kc=Ke+Kcb), potential and actual crop evapotranspiration (ETc and ETa) and net and gross irrigation requirements (NIR and GIR) were estimated for the different study levels (plot, farm and district) using spatially distributed parameters on the climate, crop, soil characteristics, irrigation system, growing season and basic irrigation management practice. These different outputs were also spatially represented using the GIS-Mod tool implemented in MABIA-REGION. The results obtained show that the irrigation's practice was seasonally variable. Thus, during the winter season, the irrigations practiced was far exceeded the irrigation water requirement estimated by MABIA-Region. While during the summer season, the irrigations carried have merely covered 44% of irrigation water requirements. Also, the study reveals a high variability in the practice of irrigation between different cultures and different farms.","PeriodicalId":117786,"journal":{"name":"2012 IEEE 4th International Symposium on Plant Growth Modeling, Simulation, Visualization and Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129275795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we propose a novel method to characterize the cell organization in light microscopic wood section images. It aims to identify automatically the cell file in a context of mass treatment. The originality of the proposed method is our cell classification process. Unlike many supervised methods, our method is self conditioned, based on a decision tree which thresholds are automatically evaluated according to specific biological characteristics of each image. In order to evaluate the performances of the proposed system and allow the certification of the cell line detection, we introduced indices of quality characterizing the accuracy of results and parameters of these results. Those are related to topological and geometrical characters of the cell file at both global and local scales. Moreover, we propose an index of certainty for selective results exploitation in further statistical studies. The proposed method was is implemented as a plugin for ImageJ. Tests hold on various wood section well contrasted images show good results in terms of cell file detection and process speed.","PeriodicalId":117786,"journal":{"name":"2012 IEEE 4th International Symposium on Plant Growth Modeling, Simulation, Visualization and Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128175993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its architecture is defined by Rauh's model, which comprises the rhythmic growth, and consequently, the existence of growth units. The aims of this study were to define the mathematical functions for growth unit formation related to various morphological parameters, to interpolate the 3D reconstructions for two-year period and to calculate the leaf/fine twig production of males and females cultivated in two contrasting environments (monoculture - and forest understory). For this purpose, InterpolMateS1, one deterministic and empirical model, has been developed. It interpolates the structural reconstructions of plants in 3D based on several known growth stages, and estimates the plant production for beverage industry. Various morphological characters were defined to parameterize the InterpolMateS1: metamer number, individual leaf size, main axes elongation, leaf number increase per axes, total leaf area, leaf shed per axes and branching. The VPlants and PlantGLViewer software were used for plant codifying and 3D reconstruction, while the modules of InterpolMateS1 were written in NetBeans IDE (Java). The cubic splines functions fitted correctly with the observed values of morphological characters during four growth flushes in two-year continuum. The out-put of useful biomass production in InterpolMateS1 was related to mock-up leaf area, fine branch volume and various forest productive parameters (i.e., specific leaf area, specific wood mass). The next steps in development of this forestry/agronomy useful software consider the coupling of yerba-mate mock-ups with carbon gain and storage on plant and landscape scale for two environments - monoculture and forest understory.","PeriodicalId":117786,"journal":{"name":"2012 IEEE 4th International Symposium on Plant Growth Modeling, Simulation, Visualization and Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123489246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
