“…With the development and applications of virtual reality and visualization technology, virtual plant has become a hot topic in the scientific domain and industrial application of agronomy and forest management. At present, the studies on longan tree paid more attention to either functional models or 3D 978-1-4673-0070-4/12/$31.00 ©2012 IEEE 371 morphological simulation of longan tree [2]. There are few models, which integrated the two aspects knowledge.…”

A longan (Dimocarpus longan Lour.) growth and development s i mulat i on model was created by i ntegrat i ng ex i st i ng knowledge of d i fferent aspect of the Longan arch i tecture and physiology. F i eld i nvestigation and measurements were conducted i n longan orchard i n order to acqu i re arch i tectural character i stics of longan tree. The three d i mensional canopy model of longan i s consisted of trunk, branches and leaves. The basic un i t of stem i s a parameter i zed segment. The 3D segment was descr i bed with cone. The leaves were depicted using parametric NURBS surface. The 3D canopy was presented by connect i ng the elements according to the tree arch i tecture and topology. Hourly photosynthesis per leaf under var i ous env i ronmental conditions was calculated, and the total photosynthesis assimilation of the young longan in growing season was estimated. Based on source-sink partition i ng theory, the biomass was allocated among organs accord i ng to the organ expansion rate and age. Tree growth i s dr i ven by the ava i lable photosynthetic products after resp i ration losses. The development of longan was reshaped by expand i ng of ex i st i ng organs or generat i ng new organs correspond i ng to the i ncrements of ass i m i lation. Thus, the s i mulation of the dynam i c growth processes of young longan under certa i n env i ronmental factors was real i zed. A Tree growth s i mulation prototype system was i mplemented. It i ncludes model i ng of tree morpholog i cal structure, accumulat i ng and partition i ng ass i m i lation products among d i fferent organs, and visual i z i ng the partition i ng outcome. The s i mulation of fruit tree growth i n v i rtual plant env i ronment w i ll be useful to understand the longan growth and to develop strategies to i mprove fruits production.
