“…Accordingly, we targeted adult trees and did not address the development of tree architecture, which is a major modelling object of FSPM models such as L-PEACH (Allen et al 2005;Lopez et al 2008) or MAppleT, where it is enriched by a biomechanical perspective . Modelling this development leads to realistic simulations of tree shaping (Lopez et al 2008). Instead, we used tree architecture as an input of QualiTree, which opens the way to combining it with tree architecture models.…”

This article presents QualiTree, a generic fruit tree model that can simulate the effects of various cultivation practices on the development and within-tree variability of fruit quality. These practices include fruit thinning, summer and winter pruning, irrigation and tree training. Combining both agronomic and physiology viewpoints, the model describes the tree as a set of objects-fruiting units organised into a tree architecture and viewed in detail, and other compartments viewed globally-that exchange carbon and are the targets of physiological functions that can be changed by cultivation practices. The complex effect of shoot removal on tree behaviour was subjected to a special modelling effort using the coordination theory. QualiTree combines existing models of fruit quality development and simple carbon allocation functions. Though parsimonious, it is able to express a high degree of variability of fruit quality criteria. Future developments of QualiTree relative to an extension of the range of fruit quality criteria and the effects of cultivation practices are also discussed.

“…The distance between 0 P and 3 P is the length of fruit axis, its value is l , the X-axis part of 2 P is half of the max fruit diameter, its value is r , the Y-axis part of 2 P is the max fruit diameter on fruit axis, 1 P is any point on the curve. So the control points of Bézier curve can be deduced by these four type value points.…”

Abstract.To simulate the apple fruit on computer effectively, analyze the characteristics of apple fruit shape and color, cubic b curve is adopted to fit the peripheral contour curve and then a model based on geometric method that use less parameters is put forward to construct apple fruit shape curve and calculate the coordinate points.The 3D simulation of the model proved that this model can construct apple fruit quickly and effectively.

“…In these simulations, mechanistic models of plant function specified at various levels of abstraction have been applied to simulate various plants. For instance, the allocation and transport of carbon has been considered in peach (Allen et al 2006, Lopez et al 2008; the relationship between plant structure, fruiting patterns and environment, and the effect of defoliation on plant structure have been addressed in cotton Hearn 2002, Thornby et al 2003); and the impact of light has been considered in various coniferous and deciduous trees (Mech and Prusinkiewicz 1996;Renton et al 2005a and2005b) and in clover (Gautier et al 2000). In the present study, we developed a mixed approach based on stochastic models for representing plant topology and mechanistic model for the geometry.…”

Construction of architectural databases over years is time consuming and cannot easily capture the event dynamics, especially when both tree topology and geometry are considered.The present project aimed to bring together models of topology and geometry in a single simulation such that the architecture of an apple tree may emerge from process interactions.This integration was performed using L-systems. A mixed approach was developed based on stochastic models to simulate plant topology and mechanistic model for the geometry. The succession of growth units (GUs) along axes and their branching structure were jointly modeled by a hierarchical hidden Markov model. A biomechanical model, derived from previous studies, was used to calculate stem form at the metamer scale, taking into account the intra-year dynamics of primary, secondary and fruit growth. Outputs consist of 3D mockups geometric models representing the progression of tree form over time. To asses these models, a sensitivity analysis was performed and descriptors were compared between simulated and digitized trees, including the total number of GUs in the entire tree, descriptors of shoot geometry (basal diameter, length), and descriptors of axis geometry (inclination, curvature). In conclusion, in spite of some limitations MAppleT constitutes a useful tool for simulating development of apple trees in interaction with gravity.
