An improvement in cold tolerance would allow earlier sowing and thus a better fit of the crop growth cycle to the environment. A field experiment with two planting dates was conducted using four maize inbred lines of temperate or highland-tropical origins. Early sowing had a major effect on plant growth and light interception, both during and after the cold period. Less striking effects were observed on phenology, mean leaf angle and radiation use efficiency. 3D virtual plants coupled with a radiative model are proposed as a tool to analyze the quantitative impact of genetic variability in different traits on light interception of early sown crops. The potential contribution of virtual plants to drive genetic studies and plant breeding for cold tolerance is discussed.","PeriodicalId":315124,"journal":{"name":"2006 Second International Symposium on Plant Growth Modeling and Applications","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127717955","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 proposed approach splits the plant geometry into clusters. On each plant primitive, ambiant occlusion approximation is then defined from statistical inner cluster properties and a fast outer cluster occlusion. The implementation achieves flexible ambient occlusion effects with linear complexity.","PeriodicalId":315124,"journal":{"name":"2006 Second International Symposium on Plant Growth Modeling and Applications","volume":"360 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115906829","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}

First, 2D photos are adopted as the input to improve its practicability and efficiency. Then, the binary tree model is used as the topological structure of the tree skeleton to accelerate the reconstructing method. And the IFS is employed to reconstruct the three- dimensional trees, especially, thin twigs to enrich the details of the tree. At last, the simulation shows the validity of the method. It is a general method and can be spread to the similar system.","PeriodicalId":315124,"journal":{"name":"2006 Second International Symposium on Plant Growth Modeling and Applications","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115565426","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}

A 50 days experiment was realized to compare, at organ level on NB, tiller pruned NB and Phyllo, morphogenesis, sugar partitioning and assimilation rate. Phenotypic data were used to optimize Greenlab parameters, considered then as process based traits. Experimental analysis showed weak modifications of pruned rice morphogenesis occurred. In contrast, Phyllo showed quicker organogenesis, small organs, no tillering, half the assimilation rate of NB, modified root sugar metabolism. Greenlab fittings on observations were good except for NB, mainly because of the difficulty of correctly optimizing numerous small leaf sinks (generated by process) compared to a single big root sink compartment. However, Greenlab successfully sensed the phenotypic differences underlined experimentally, in particular, modified carbon sink to source relationships for Phyllo. Modeling analysis of rice tillering cases shows that Greenlab has a great potential as heuristic approaches to be applied to plant phenotyping, more case studies are proposed to testing the model as a suitable tool to assist to screen plant phenotype.","PeriodicalId":315124,"journal":{"name":"2006 Second International Symposium on Plant Growth Modeling and Applications","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125020856","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}

It predicted the number and basal area of trees for 5 species groups (spruce, balsam fir, other softwood, soft hardwood and hard hardwood) and 10 diameter classes. Upgrowth, ingrowth and mortality models were established with explanatory variables representing tree size, stand density and stand structure. The model was based on 305 sample plots with inventory periods from 2 to 9 years. The majority of the data (80%) was used for model development, and the rest (20%) was used for model validation. It was concluded that the model is a reliable and fairly accurate tool for short-term prediction of growth of spruce-balsam fir forest in Canada.

Individual plants were observed infield trials throughout their growing period and their 3D architecture (AM) was reproduced at all growth stages. The crown envelope of the GM was represented by an ellipsoid. The ellipsoid content consisted of foliage elements randomly dispersed in a planophile distribution. The radiative transfers of both plant representations were simulated in the PAR range using the ARCHIMED simulation platform. Different ellipsoid envelope and foliage element sizes were investigated. With an appropriate set of sizes, light interception calculated using GMs tallied well with that obtained using AMs. It can be concluded that a simple turbid medium model is sufficient for modelling GM content without needing to introduce a clumping factor.","PeriodicalId":315124,"journal":{"name":"2006 Second International Symposium on Plant Growth Modeling and Applications","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126780145","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}

Growth results from light interception and photosynthesis, taking respiratory losses into account. Carbon partitioning and source-sink relations determine the growth rate of simultaneously growing organs. Development can be described as a temperature dependent rate of progression through the life cycle, but needs to include organogenesis and the fate of buds if the model addresses plant structure. The most important concepts used in modelling are highlighted, making a distinction between proces-based (crop) models and functional-structural models. It is stated that truly functional-structural models, that integrate aspects of plant structure and plant function, need extended knowledge of the factors responsible for dormancy or outgrowth of each bud.","PeriodicalId":315124,"journal":{"name":"2006 Second International Symposium on Plant Growth Modeling and Applications","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126385573","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}

This idea is implemented in a new simulation platform (CrossTalk) illustrated here with a simulation linking a soil water-transport model (WAVE, Fortran), a shoot architecture model (MacTom, C) and a root architecture model (RootTyp, Java), none of which had been designed with the intention to be used as Lego blocks in a larger simulation framework.","PeriodicalId":315124,"journal":{"name":"2006 Second International Symposium on Plant Growth Modeling and Applications","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132419015","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}

Merr.] plants grown under five management strategies differed significantly in their geometric structures, and were classified with 75 to 100% correct classification, based on differences in their fractal dimension (Do), midday differential canopy temperature (dT), and canopy light penetration [Log(UIo)]. Single soybean plants grown under a conventional system using moldboard tillage developed complex geometric structures, with significantly larger Do (1.477) values and grain yield (11.2 g per plant) as compared to plants grown under an organic system with strip tillage (Do =1.358, and grain yield = 2.32 g per plant). Across management strategies, Do of single plants was a function of stem perimeter, circularity, and volume, and plant dry weight; whereas grain yield m was a function of Do, plant dry weight and volume, and stem circularity. Knowledge of how plants respond to single and multiple management strategies will help agronomists develop better predictive models and will help farmers refine management practices to optimize yield.","PeriodicalId":315124,"journal":{"name":"2006 Second International Symposium on Plant Growth Modeling and Applications","volume":"156 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121449932","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}
