A revised dual-scale automation was developed to simulate plant architecture of a desert shrub, Haloxylon ammodendron, according to its morphological characteristics. The above-ground part was simulated by a basic structural unit of shoot which was simplified from the internodal segment and squama (the degraded leaf). The thermal time, determined by the changes of outer morphology, was used as the...
The topological structural model of root system was developed in this study, which was the first work of developing a functional-structural model of root system. Referring to the equal thermal interval, the basic structural unit of root (UR) was defined, and then the branching density (BD) and branch probabilities branching probability vector (BP) of UR were used to describe the number and type of...
R/FR (red to far-red ratio) is a key light signal for plants to detect the oncoming competition and initiate the shade avoidance syndrome. This study is aim to simulate the R/FR signal received by maize plants based on a 3D canopy radiative model. Optical properties of maize leaf were characterized by an adapted Cook-Torrance model for reflectance and a Lambert model for transmittance. Virtual maize...
Improving plant structure is pivotal for increasing the potential yield of crops. The aim of this paper was to evaluate the influence of leaf angle and leaf area index (LAI) on light interception efficiency and capacity of biomass production of rice using 3-D models. A group of virtual plant types of rice, with different combinations of leaf angles, was designed based on the 3-D data of a real rice...
